Can a Caterpillar Be Charismatic?

By Edie Parnum

Yes, of course. I was thrilled to discover a brown-hooded owlet in my late October garden. This caterpillar with its glossy yellow, red, blue, and black pattern is beautiful. It is pre-frost as I write, so the leaves of the aster where it’s feeding are still green and evidently tasty.

For three days I’ve watched it feeding and pooping. Thankfully, the nearby hungry birds have not spotted it. Frost is coming, so I hope it will soon crawl down the aster plant where it has been feeding and make its pupa. As a caterpillar this insect won’t live through the winter, but its pupa can survive unseen in the soil or decaying leaf litter. In the spring after undergoing metamorphosis, a drab brown one-inch adult moth will

emerge. This night-flying moth will visit flowers for their nectar and spread the pollen to fertilize other plants. Then it will mate and lay eggs on asters and goldenrods that will hatch into these caterpillars. To complete its entire life cycle, my caterpillar needs humus-rich soil, native asters and goldenrods, and nectar-rich perennial flowers.

The brown-hooded owlet is my favorite caterpillar. I wish more people had favorite caterpillars. They are essential bird food and as adults become excellent pollinators. In the case of the brown-hooded owlet caterpillars, they require native asters and goldenrods as their host plants.

We need beautiful caterpillars and drab ones, too. Without them birds will suffer, plants (including our food plants) will be less plentiful, and our lives less rich. Let’s plant more host plants and leave decaying leaf litter for the caterpillars.

Every year we feature two superior native plant species.  One of the Prime Plants for Nature is a tree, shrub, or vine and the other is a perennial.  Prime Plants are selected based on these criteria:

  1. Native to southeastern Pennsylvania
  2. Offer high wildlife value and contribute significantly to your property’s web of life
  3. Provide food for wildlife by producing nutritious fruits, seeds, nuts, nectar, or pollen
  4. Most host insects that are eaten by birds or other animals
  5. Offer shelter and places to raise young
  6. Easy to grow and make an attractive addition to your landscape
  7. Sold at native plant nurseries and native plant sales. (See list of local sources for native plants at the end).

Our selections for the 2019 Prime Plants for Nature awards are:

Amelanchier canadensis, Serviceberry (also known as Juneberry or Shadbush) A. arborea and A. laevis are closely related species.

Wildlife Value: In the early summer this small tree produces berries relished by American Robins, Gray Catbirds, Cedar Waxwings, and Northern Mockingbirds. Other birds and mammals eat the fruits as well. The popular fruits disappear quickly, often before they are completely ripe. The foliage of Serviceberry is food for 124 species of caterpillars including Striped Hairstreak and Red-spotted Purple butterflies and Blinded Sphinx and Small-eyed Sphinx moths. The nectar-rich flowers attract adult butterflies, bees, hummingbirds, and other pollinators.

Growing Conditions:  Serviceberry is easily grown in sun or part shade.   It prefers moist soil, but will tolerate a variety of conditions. Although sometimes subject to rust or leaf spot, it is normally free of any severe problems. Rust (Apple Cedar rust) can be a problem for anyone who also has nearby Eastern Red Cedar.  It is moderately deer-resistant.

attractive fall foliage is yellow to orange-red.  Amelanchier canadensis, A. arborea, and A. laevis are closely related species that hybridize and are difficult to differentiate unless you are a

botanist.

The Serviceberry should not be confused with Bradford Pear, also known as Callery Pear, an invasive tree with similar white flowers that blooms at the same time.  The Bradford Pear has upright branches and denser, dark foliage. It out-competes native species, hosts very few native insects, and produces fruit that is unpalatable to birds and other wildlife.  For more info about invasive Bradford/Callery Pear in Pennsylvania, click here.

Garden Phlox, Phlox paniculata

Wildlife Value: Garden Phlox is a nectar-rich perennial that attracts native pollinators including butterflies, bees, moths, and hummingbirds. The flower petals are fused into a tube (corolla). To access the nectar, a pollinator inserts its tongue (proboscis) into the bottom of the corolla.

Butterflies and large bees with a long proboscis and hummingbirds can reach the nectar.  Small bees such as Sweat Bees, Yellow-faced Bees, Leafcutter Bees, and small carpenter bees have a proboscis that is too short to reach the nectar.  However, all will pick up pollen as they rub against the anther (male part) at the top of the corolla. Flying from flower to flower, these pollinators carry the pollen to the stigma (female flower part) of each bloom. As a result, reproduction occurs.

Among the insect pollinators using Garden Phlox, Hummingbird

Clearwing Moth is a conspicuous day-flying sphinx moth that is sometimes mistaken for a hummingbird.  Also look for Peck’s Skipper, a small tan butterfly.

Growing Conditions:   Garden Phlox will grow well in sun or part sun in moist to average (tolerates clay) soil.

Appearance: The pink, lavender, or white flowers bloom profusely in late summer and early fall on 3-4-foot plants. Many cultivars (often referred to as navitars) are

available, but some have reduced nectar production.  However, according to studies performed at Mt. Cuba Center, ‘Jeana’ produces nectar abundantly and attracts many pollinators.  Garden Phlox can develop mildew during hot, humid summer conditions.  Removing some of the flower stalks will improve air circulation and prevent mildew.  According to Mt Cuba, the ‘Jeana”, ‘Robert Poore’, and ‘David’ cultivars are mildew-resistant.

Other phlox species:  Woodland Phlox, Phlox divaricata, and Creeping Phlox, P. stolonifera, are spring-blooming phlox species that grow in part shade or shade. They attract a variety of pollinators including butterflies and hummingbirds. The flower structure is similar to Garden Phlox.

Native Vines for Beauty and Wildlife Value

Posted on by

 By Barb Elliot

Vines have a bad rap. Invasive non-native vines like Kudzu, Oriental Bittersweet, Japanese Honeysuckle, Porcelain Berry, and English Ivy grow up and over trees, often smothering whole forest edges.  By making them top-heavy, these vines can damage and pull down entire trees.  However, not all vines are bad actors.  Most locally native vines are attractive and well-behaved.  By providing food, shelter, and nesting places, they add high wildlife value to our habitat gardens.  I have three of these natives and I highly value the roles they play in my garden.

Trumpet Honeysuckle, Lonicera sempervirens

With Trumpet (aka Coral) Honeysuckle in your yard, Ruby-throated Hummingbirds will visit – guaranteed!  This native honeysuckle is not at all like its unruly cousin, Japanese Honeysuckle. Handsome and well-behaved, this vine sports blue-green foliage and coral-red trumpet-shaped flowers.  It’s easy to grow in average, well-drained soils with medium moisture. A twining 10-15’ vine that needs a support, it is striking on a fence or trellis with its profusion of flowers.   It grows in shade, but flowers best in full sun.  Trumpet Honeysuckle begins blooming in April or May and blooms intermittently through summer and into the fall.  In autumn, birds eat the red berries.

Trumpet Honeysuckle provides food, shelter, and nesting locations.  One year, American Robins built a nest in one of my honeysuckle vines.  A vine growing close to my bird feeders provides shelter for birds escaping hawks and other predators. According to Doug Tallamy, this honeysuckle hosts up to 33 species of butterfly and/or moth caterpillars that eat its leaves.  Among them are two day-flying hummingbird look-alike moths. the Hummingbird Clearwing and Snowberry Clearwing.

Trumpet Honeysuckle is truly beloved by hummingbirds.  I love to sit on my deck and watch these flying jewels sip nectar from the long tubular flowers and even fight over the blossoms.  George Washington grew this vine at his Mount Vernon estate where it is still grown today.  In a 1785 diary entry, Washington described planting it around columns and along walls.  Perhaps he, too, enjoyed the hummingbirds that visited his Trumpet Honeysuckle.

Virginia Creeper, not to be confused with Poison Ivy, is a beneficial vine that’s entirely harmless to humans.  To differentiate the two plants, look at the leaves. Poison Ivy always has 3 leaflets per leaf,  but Virginia Creeper has 5 leaflets. Some young Virginia Creeper vines may have a few leaves with just 3 leaflets, but most leaves will have 5 leaflets.  The green leaves are handsome and in full sun turn bright red or purple in October.

Offering high wildlife value, Virginia Creeper hosts 32 species of caterpillars, including the striking Pandora Sphinx and Abbott’s Sphinx moth caterpillars.  These are my most sought after caterpillars, but I have yet to find either of them.  However, as a consolation, I’ve discovered several Virginia Creeper Sphinx moth caterpillars, which I raised to become beautiful adult moths.

In spring, the wildlife-friendly Virginia Creeper’s inconspicuous flowers attract bees and other small pollinators.  Thirty species of birds, including chickadees, woodpeckers, robins, catbirds, warblers, and bluebirdsrelish the dark blue berries in autumn.  Reddish fall foliage and the bright red stems of the berries lure the birds.  Small animals use this vine for cover, especially when it grows along the ground.  A few years ago, Northern Cardinals built a nest in the Virginia Creeper growing on my arbor.

A deciduous woody vine, Virginia Creeper is easy to grow in full sun to full shade in well-drained soil with average moisture.  It will climb brick or stone walls, trellises, arbors, fences, or large trees. One of my favorite ground covers, it will happily cover a stump or wood pile. Although a vigorous grower, climbing 30’ feet or more, it will not smother trees.  If it becomes unruly, it can easily be pulled down or cut off at the base where it will re-sprout.

Virgin’s Bower, Clematis virginiana

Virgin’s Bower, a native clematis, is a superb plant for pollinators.   Its small white flowers have a pleasing, sweet fragrance and cover the foliage from mid-to late-August into September.  The flowers attract many pollinators, including butterflies, bumble and other native bees, plus interesting wasps and flies.  Intent on collecting nectar and pollen from the flowers, they are usually oblivious to my presence.

Predators like spiders and centipedes furtively wait to catchthe unsuspecting pollinators. I have spent hours, both day and night, watching the pollinators and dramas of nature play out on Virgin’s Bower.

Virgin’s Bower is very easy to grow in medium to wet well-drained soil in part shade to full sun.   Although I love this vine, it is not for the faint of heart. It is a vigorous grower, and if given support, will climb to 20’.  When growing along the ground. it can spread into a tangled

mass.  The vines can take root where they touch the ground.  Seeds from its attractive seed heads are windblown, so new plants can pop up elsewhere in your yard.  But if you are diligent and keep this vine in check, you and many pollinators will be well-rewarded by your efforts.

Now is a good time to add these vines to your landscape.  If you have a small space, Trumpet Honeysuckle will work well.   For larger areas, try Virginia Creeper or Virgin’s Bower.  These vines will add texture and interest to your landscape. Pollinators, birds and other wildlife will thrive in your garden.

Wildlife Value: In the fall this shrub produces high-lipid red berries that are valuable formigrating birds including Gray Catbird, American Robin, Hermit Thrush, and other thrushes. The foliage of Spicebush is food for the

Spicebush Swallowtail Butterfly caterpillar.  In fact, this caterpillar species is entirely dependent on Spicebush and its close relative, Sassafras, for its sustenance. Spicebush is also a host plant for Eastern Tiger Swallowtail and Promethea Moth. The flowers are pollinated by small native bees, wasps, beetles, and flies.

Growing Conditions:  This fast-growing, disease-free shrub will thrive in a variety conditions from semi-sun to shade in average to moist soil.  Its natural habitat is the understory of moist woodlands or woodland edge. The leaves, twigs, and other plant parts are spicy when crushed, so deer don’t usually browse this shrub.

Appearance: The Spicebush is a multi-stemmed 6-12’ deciduous shrub. Its blossoms appear in early spring before the foliage emerges. Although the flowers are small, they create a nice show of yellow haze when little else is blooming. Because this shrub is dioecious, male and female flowers occur on separate plants, and the berries form from female flowers. The fall foliage is yellow.

 

Purple Coneflower, Echinacea purpurea

Wildlife Value: Purple Coneflower’s pollen and nectar are magnets for many bees and butterflies.  Bumble bees and short and long-tongued bees such as small carpenter, sweat, long-horned, digger, and mining bees plus long-horned beetles visit the flowers. Butterflies such as swallowtails, sulphurs, fritillaries, Red Admiral, American and Painted Ladies, Monarch, and skippers are attracted also.  Crab spiders may lurk in the flowerheads to capture both beneficial and pest insects.   A few moth caterpillars will eat the flowers and leaves including Blackberry Looper, Camouflaged Looper (adorns itself

with flower parts to avoid predators), Common Pug, and Sunflower Moth.  In late summer and fall the coneflowers’ seeds are eaten by American Goldfinch and other finches.

Cultivars of Purple Coneflower are frequently sold. When purchasing plants, if possible, choose straight native species. Some cultivars selected by breeders change the shape or color of the flowers and possibly reduce the amount of pollen and nectar. For instance, Purple Coneflower ‘Pink Double Delight’ with its double flowers is less attractive to pollinators.

Growing Conditions:   This trouble-free perennial grows in moist to average soil with sun or part sun.  It can survive heat and moderate draught drought conditions.  Because it prefers lean, poor soil, fertilizer and other amendments are not recommended. The parent plant produces seedlings that can be easily transplanted.  The roots of 3-4-year-old plants can be divided and transplanted, too. Normally, neither deer nor pests are a problem.

Appearance: Purple Coneflower with its pinkish-purple flowerheads is one of our prettiest native perennials.  It grows 3-4 feet tall on sturdy stems that do not require staking.  This perennial blooms from July-September.  Cutting back the spent flowers can extend the blooming period.

A Note of Caution:  Many retailers sell plants treated with pesticides containing neonicotenoids.  These long-lasting pesticides are absorbed into the entire plant.  Insects eating the pollen, nectar, leaves, or any plant part are poisoned. According to the National Wildlife Federation, neonics are “found in hundreds of products, including sprays, granules, tree injections and soil drenches (pesticides applied to the base of plants).”  To avoid neonics, “carefully read labels. Steer clear of products that contain imidacloprid, acetamiprid, dinotefuran, clothianidin or thiamethoxam.”  If it’s not apparent that plants are neonic-free, before you buy, ask the seller to verify that neither they nor their grower treat plants with neonics in any way, including growing them from neonic-coated seeds.  See https://www.nwf.org/Magazines/National-Wildlife/2018/Feb-Mar/Gardening/Nixing-Neonics

 

Pollinators Come to a Tiny Urban Yard

By Edie Parnum

A 130-square foot cement-covered backyard —who would expect such a yard could be a haven for wildlife?  The property is on a narrow street of rowhouses in Philadelphia.  The nearest park is several miles away. Nonetheless, this garden is teeming with  butterflies, bees, wasps, moths, and a host of other pollinating insects.

A view of Navin’s small backyard. Photo by N. Sasikumar. Click to enlarge.

Navin, an avid amateur naturalist, moved to this property last fall.  He saw the potential to attract pollinators with native plants in raised beds and containers.   In early spring, he invited me for a Backyards for Nature consultation.  Together we made a list of short and mid-sized perennials that bloom from early spring to late fall and are known to attract a variety of pollinators.

He purchased good quality plants from Good Host Plants, a native plant nursery in Philadelphia. He planted perennials in two raised beds that sit atop the cement.  Others he planted in large, deep containers. He installed two trellises for growing vines.

It worked.  In the spring bees and other insects found the Wild Columbine (Aquilegia canadense), Beardtongue (Penstemon digitalis). and Creeping Phlox (Phlox subulata).  The summer blossoms of Swamp Milkweed (Asclepias incarnata), Butterfly Weed (A.tuberosa), Purple Coneflower (Echinacea purpurea), Joe-Pye Weed (Eutrochium purpureum), Dense Blazing Star (Liatris spicata), Cardinal Flower (Lobelia cardinalis), Wild Bergamot (Monarda fistulosa), Short-toothed Mountain Mint (Pycnanthemum muticum), and Orange Coneflower

(Rudbeckia fulgida) host many butterflies and other pollinators.  The show continues this fall with Grey Goldenrod (Solidago nemoralis), New England Aster (Symphotrichum novae-angliae), and other asters.  Trumpet Honeysuckle (Lonicera sempervirens) and Virginia Creeper (Parthenocissus quinquifolia) will bloom on the trellises.

On weekends Navin observes and photographs the wildlife in his

garden.  He discovered Monarchs laying eggs on his Swamp Milkweed.  An insatiable predator, a Carolina Mantis (our native mantid species) lurked nearby, so he decided to bring the Monarch eggs and caterpillars inside to raise them in safety.  So far, he’s raised and released 34 adult Monarchs.  An additional 47 are either chrysalises or caterpillars and will be released soon for their journey to Mexico.  He’s also rearing BlackSwallowtail eggs and caterpillars that grow on parsley.  According to Navin, nighttime is the best time for spotting the small eggs and caterpillars.

So far, he’s recognized ten additional butterfly species including Eastern Tiger Swallowtail, Red Admiral, and Eastern Tailed Blue.  The biggest surprise was a Giant Swallowtail, a southern species rarely seen in

the Philadelphia area. Other insects are finding his garden, too.  Navin observed a Snowberry Clearwing, a large day-flying moth, nectaring on blossoms like a hummingbird. A variety of bees, wasps, flies and moths feed on nectar and pollen.  With so many insects, predators such as the Carolina mantis as well as spiders,lacewings, and parasitic wasps have located his yard, too.  One day he spotted a lacewing eating aphids.

Navin offers advice to other wildlife gardeners with limited space.   A great many plants can be crowded into small garden plots, raised beds, and large, deep containers.  Prune the plants periodically to keep them short and use stakes before tall plants get floppy. Water frequently in hot weather.

Navin submits his wildlife sightings to iNaturalist, a nature record-keeping app.  He photographs the butterflies and moths (both adults and caterpillars), bees, wasps, flies, beetles—in fact, any creature using his plants.  He uploads these photos and the species names to iNaturalist. The dates and location are automatically included.  When the species is unknown, iNaturalist experts can usually provide the identification.  Scientists and other amateur naturalists can view and study Navin’s sightings and those of the other 137,000 iNaturalist users.

How do so many creatures find this yard?  Certainly, adult butterflies and moths can fly.  They’re wired to find nectar and pollen for their survival.  With their chemical sensors, they can also locate the specific plants they require to lay their eggs.  Other insects have powerful search mechanisms, too.

Navin will keep searching.  He’ll find more creatures.  After all, this garden is only 6 months old.

nourishes our Ruby-throated Hummingbirds. Butterflies and bumblebees use the nectar and pollen. As with other native plants, the foliage is food for native caterpillars, including Spring Azure butterflies and moths such as Hummingbird Clearwing (Hemaris thysbe), Snowberry Clearwing (Hemaris diffinis), Harris’ Three-spot (Harrisimemna trisignata), and Great Tiger Moth (Arctia caja). These caterpillars in turn are food for birds and their nestlings. Songbirds occasionally eat the red berries.

Aster flowers. Sweat bees, leafcutter bees, carpenter bees, mining bees, and bumble bees are attracted to the blooms’ bold, contrasting colors. The flowers are an important nectar source for Monarch butterflies during their fall migration. The foliage hosts 109 species of caterpillars (per Doug Tallamy, Bringing Nature Home: How You Can Sustain Wildlife with Native Plants, 2007) including the Pearl Crescent butterfly. Moth species include Saddleback caterpillar, several geometers, and Brown-hooded Owlet.

of brightly colored blossoms, each 1 ½” across, appears in late summer and persists until fall. The flower rays are bright pink or purple, the central florets yellow-orange. The plant grows 3-6 feet high and may require staking. In a small garden, keep the plant from getting too tall by pinching back the top growth in early June and then again in early July. The flowers are attractive additions to flower arrangements. Cultivars are available in a variety of colors and heights.

Summer Magic in Barb’s Yard

By Barb Elliot

When I leave my house to explore my backyard, whether by day or after dark, I enter another world.  Transported from daily cares, I anticipate experiencing the wonders of nature. What’s happening at this season? What creatures will I encounter?  What mysteries will unfold?  I am rarely disappointed. Life is abundant in my yard because the numerous native plants I’ve planted meet the food and shelter needs of many animals.

This summer I photographed some of what I observed.  Here are highlights.  Enlarge any photo by clicking on it. 

Early Summer

Interesting pollinators gather nectar and/or pollen from my Highbush Blueberry flowers, including a Flower Longhorn Beetle  and an unknown flower fly – a good Yellow Jacket wasp mimic.  A native Green Sweat Bee on a Black-eyed Susan is covered with yellow pollen grains.

Midsummer

In July, I find a variety of beetles.  My favorite, the Dogbane Beetle, is on a Dogbane plant.  A tiny (less than 1/4 inch) colorful beetle, the Mottled Tortoise Beetle  appears during the day (wearing its little translucent skirt!).  A longhorn Ivory-marked Beetle, comes to night lighting.

The right side of the patio area sports both Cardinal Flower  and Great Blue Lobelia . Pickerel Rush grows in the pond on the left. The tall plants with yellow flowers in the background are Cup Plant. Cardinal Flower nectar is enjoyed by a Spicebush Swallowtail that lost part of its left hindwing.  Probably a hungry bird tried unsuccessfully to capture this butterfly.

Cup Plant attracts many pollinators, including bees, butterflies, and moths.  At night I find a Grape Leaffolder Moth sipping nectar.  One of many bumble bees that worked hard gathering nectar and pollen during the day sleeps on a Cup Plant flower.  At night, I often find bumble bees sound asleep on flowers in my garden.

Several types of native bees are busy pollinating my flowers.  Of special interest, bumble bees are performing buzz pollination on my Flowering Raspberry flowers.  Bumble bees vibrate their wings at specific frequencies to get some species of flowers to release their pollen.  Note that bumble bees are used for buzz pollination of a number of crops, including tomatoes, blueberries, eggplants, and cranberries.  The non-native honeybee is not able to buzz pollinate.

I find a small green Nessus Sphinx moth caterpillar on native Enchanted Nightshade (Circaea lutetiana) and decide to raise it in a small enclosure with several inches of loose soil.  I feed it fresh leaves and within a week or so, it grows to over two inches long, molts into a brown caterpillar, and later burrows into the soil to pupate.  I have to wait until next spring to see it emerge as a beautiful day-flying hummingbird-like moth.

One night a strange-looking treehopper, possibly a Buffalo Treehopper, appears near my porch light.  Even more strange and ominous-looking, a very large robber fly the size of a large wasp hunts from a perch above my pond. These flies prey on large insects such as bees and wasps and will hang from one foot while devouring a victim.

Late Summer

A Shadow Darner dragonfly dries and expands its wings after emerging from the pond where it spent its nymphal stage.  The nymph recently crawled out of the pond and shed its exoskeleton. Because I find numerous shed skins (exuvia) during the summer, I know that my pond produces a good number of dragonflies.

Eastern Tiger Swallowtails and Skippers are frequent visitors at my Garden Phlox.  I am happy to find a Monarch, too, but regret that this is the only one I’ve seen in my yard all summer.  It’s a female, so hopefully she laid eggs on my milkweed.

My Virgin’s Bower vine begins to bloom in late August and hosts a myriad of pollinators twenty-four hours a day.

Predators such as harvestmen (“daddy longlegs”) and centipedes linger around the Virgin’s Bower vine to catch unsuspecting victims.  As I watch, a Spotted Orb Weaver spider quickly paralyzes the moth that flies into its web and then wraps it in silk.

By mid-September, I see some fall migrating birds in the yard, including a Northern Parula and Common Yellowthroat.  Both find insects on my native plants that will fuel their journeys to the tropics.

A Red-spotted Purple caterpillar has eaten the tip of a Black Cherry leaf in a pattern characteristic of this species.  I watch it grow for almost a week.  Then one night I make a gruesome discovery.  A spider has found my caterpillar and is in the process of sucking its life fluids.  However, I find another small Red-spotted Purple caterpillar a few feet away.  I’m hopeful this one will successfully overwinter and make it to adulthood.  If so, next summer it will grace my yard as another beautiful Red-spotted Purple butterfly.

Native Groundcovers

Posted on by

By Edie Parnum

A friend enjoys weeding. A peaceful, blissful occupation, she claims. And, the weed-free results please her.  Another friend likes mowing his lawn for reasons I can’t possibly imagine.  Most of us dislike these onerous, time-consuming chores.  We want weed-suppressing, mow-free groundcovers.

Don’t plant Japanese Pachysandra, English Ivy, or Periwinkle. They are popular because they spread aggressively.  In truth, they are non-native invasives that choke out native plants.  They can escape from where you’ve planted them and degrade the wildlife-friendly gardens you’re establishing and even nearby healthy natural areas. If you already have these garden thugs, get rid of them.

Good native plant groundcovers are available. These plants are hardy and shade the ground sufficiently to prevent most weeds from germinating. Selections are available for a variety of conditions including sun or shade and moist or dry soils.  Here are some of my favorites.

Allegheny Pachysandra (Pachysandra procumbens) is a dependable, deer-resistant

groundcover. The evergreen, mottled leaves are handsome. Each plant forms a clump that gradually expands. You can form new plants by dividing and transplanting older plants.  Or, you can pull on a stem to unearth a piece of root with its rhizome; this root cutting can be planted elsewhere. In the early spring this native pachysandra sports white bottlebrush-like flowers that attract bees and other pollinators.

Another favorite, Foamflower (Tiarella cordifolia), grows easily in part sun or shade. The variegated, semi-evergreen leaves hug the ground just as you want in a groundcover. The plant spreads by sending out runners (stolons). These can be transplanted to extend your bed or start a new one. A bed of Foamflowers produces a cloud of pretty white blossoms in spring.  Think of them as fairy wands, if you like.  And, deer don’t usually bother them.

Wild Ginger (Asarum canadense) is an ideal groundcover for a shady spot. The handsome flat, shiny leaves cover the ground, so most weeds can’t penetrate.  This vigorous plant spreads at a moderate pace and is unattractive to deer. A member of the Pipevine family, Wild Ginger is a host plant for the Pipevine Swallowtail butterfly.

Golden Ragwort (Packera aurea) grows well in a sunny area but can handle part-shade, too. In spring a mass of these plants will create a drift of appealing yellow flowers that attract pollinators.  After the flowering season, you can cut back the unsightly dead flower heads.  The plants will continue to shade out weeds. Deer don’t usually bother eating it.

Seersucker Sedge (Carex plantaginea) is named for the crinkled texture of the leaves. These attractive strap-like leaves are arranged in a ground-hugging rosette. Although it doesn’t creep, you can plant them close together to create a groundcover. This sedge is good for edging, too.

 

 

By listing Obedient Plant (Physostegia virginiana) here, I’m stretching the definition of a groundcover. This plant doesn’t hug the ground;  it’s 3-5 feet tall.  However, a clump of this

plant will spread and cover as much area as you like.  In summer it has spikes of beautiful pink or lavender flowers with nectar that hummingbirds, butterflies, bees, and other pollinators relish.  Don’t worry about its aggressiveness; it’s easy to cut out the edges to keep it a manageable.  .

These and other groundcovers (see list below) can fill in anywhere you have patch of bare ground. If the space isn’t suitable for a tree or two, shrubs,or a perennial bed, plant native groundcovers. You can use them instead of turf grass, too.

Establishing a bed of groundcovers can be done gradually and relatively cheaply. Start with a few plants in a small area. After a year or so, divide these plants to form new colonies. To create an attractive combination of multiple species, consider height, color, texture, and bloom time.  The plants will soon touch each other as they do in nature.

.With native groundcovers you’ll have an easy-care garden that’s pretty and appealing to wildlife. As always, with more native plants you’ll observe more birds, butterflies, and other native insects. Also, groundcovers will give these creatures more places to seek shelter. You’ll be pleased to see the vitality of nature in your yard.

Prime Plants for Nature: Backyards for Nature 2016 Native Plant Awards

Posted on by
Reply

By Edie Parnum

Every year we feature two superior native plant species.  One of the Prime Plants for Nature is a Tree or Shrub and the other is a Perennial.  Prime Plants are selected based on these criteria:

  1. Be native to southeastern Pennsylvania.
  2. Offer high wildlife value and contribute significantly to your property’s web of life.
  3. Provide food for wildlife.  Nutritious fruits, seeds, nuts, nectar, or pollen are produced by the plant.  Most host insects that are eaten by birds or other animals.
  4. Offer shelter and places to raise young.
  5. Be easy to grow and make an attractive addition to your landscape.
  6. Sold at native plant nurseries and native plant sales.  (See list at end of article.)

Our selections for the 2016 Prime Plants for Nature awards are:

Black Cherry, Prunus serotina                                                                         

Wildlife Value: This medium-sized deciduous tree delivers exceptional wildlife value.

According to Doug Tallamy, author of Bringing Nature Home: How You Can Sustain Wildlife with Native Plants, it hosts 456 species of moths and butterfly caterpillars.  The foliage-eating caterpillars include Red-spotted Purple butterflies and moths such as Luna, Polyphemus, and Cecropia.  The tree is not defoliated because many migrating and breeding birds including warblers, vireos, and thrushes feed on these caterpillars.  Yellow-billed Cuckoos will eat Eastern Tent Caterpillars.

Growing Conditions: Adaptable to a variety of situations, sun or part sun, dry to moist soil.  Seedlings can be transplanted.

Appearance: Medium to large fast-growing deciduous tree with dark, peeling bark.  White flowers bloom in May on drooping stalks called racemes.  The reddish-black fruits ripen in late summer.

Cardinal Flower, Lobelia cardinalis 

Wildlife Value: If you want to entice hummingbirds to your yard, this is a must-have perennial.  Ruby-throated Hummingbirds are attracted to the Cardinal Flower’s brilliant red flowers and are its primary pollinators. The nectar is very sweet, twice as sweet as a soda.  A hummingbird’s bill is long enough to reach the nectar deep inside the tubular

flower.  The feathers on the head pick up the pollen and carry it from one plant to another. Cardinal Flowers bloom for six weeks in the late summer during the hummingbirds’ southbound migration. Bees rarely visit these flowers because their proboscis is too short to access the nectar.

Large swallowtail butterflies can reach the nectar with their long proboscis but are unable to pick up and transfer the pollen.

Growing Conditions:  Cardinal Flower is a trouble-free perennial that enjoys moist soil.   It will grow in average soil in a shady location. Not a true perennial, the plant and roots die after the growing season. However, the next spring it produces off-sets that will flower or can be transplanted to new locations.  The parent plant also produces seedlings that can be transplanted.  In the late fall, lay the flower stalk on the ground where you want seedlings to sprout in the spring. Appearance:  The striking red flowers are arranged along 8” spikes called racemes.   The plant grows 2 ½ -3 feet high.  The flowers are attractive additions to flower arrangements.

Edie’s Garden—A Place to Discover Nature

Wildlife is abundant in Edie’s yard.  She finds birds, butterflies, moths, dragonflies, bugs,

beetles, bees, wasps, flies, and more – creatures she loves – living among her native plants.

It wasn’t always this way.  I saw the yard when Edie moved to this ¾-acre property in 2007. It was mostly turf grass. Except for a few native trees (Black Cherry, Red Maple, White Pine), no native plants grew here. Consequently, we observed few birds—just an occasional robin or starling—no other wildlife.  She knew she could transform her lifeless property into a healthy habitat for wildlife by reducing the lawn and planting native plants. It could become a place where she could discover, learn, and enjoy nature.

To create a healthy ecosystem on her property she wanted to:

  • Plant a diversity and multitude of native plants
  • Offer conditions for birds and other creatures to thrive and reproduce
  • Provide year-round food sources, water, cover, and places to raise young for wildlife
  • Welcome lots of birds—certainly hummingbirds
  • Create a place of beauty where she could be immersed in nature
  • Learn the species of flora and fauna and how they interact and depend on each other
  • Leave a legacy of nature for future generations with long-lived trees and shrubs

Gradually, year by year, she has succeeded in creating this haven for wildlife.  Eight years later I see thousands of native plants.  They include perennials, grasses, vines, ferns, and woody plants, i.e. shrubs and trees.  She planted densely, letting the plants touch each other as they do in the wild.  Her canopy trees are young, but the oaks and others will be massively productive for wildlife for decades.  Eastern Redbud, Flowering Dogwood, and Shadbush are already filling the understory.  The mature shrubs like Spicebush, Elderberry, and several viburnum species are now luxuriant.  At the ground

level perennials, vines, ferns, sedges, and grasses, are profuse. This diversity of plants offer nuts, seeds, berries, nectar, and pollen.  Even the foliage of the native plants is indirectly a source of food.  Insects eat the leaves and become food for birds and other creatures.

Birds now find what they need to live and thrive. They eat the fruits, nuts, seeds, and nectar produced by the yard’s native plants.  Resident and migrating birds eat the insects hosted by her native plants. For example, Carolina

 

Chickadees can locate the 6, 000-plus caterpillars required to feed their young.  Of course, no pesticides are ever used.

Edie has added other features for birds.  She installed nest boxes for cavity-nesting House Wrens and Tree Swallows.  She allows fallen leaves to lie in many places. Eastern Towhees and Brown Thrashers rummage in this leaf litter to find insects. Carolina Wrens

often locate their insect delicacies in the brush pile. On a snag (dead tree) woodpeckers, including a Pileated Woodpecker, forage for insects in the decaying wood. A Trumpet Vine grows on this snag and attracts hummingbirds seeking nectar from its flowers. A bird bath and small pond offer birds water. The bird feeders supply a small proportion of food needed by some of the birds. Many, many birds (106 species) love this yard.

Her meadow, in my opinion, is the crown jewel of her property.  It is chock full of colorful perennials and grasses.  Birds forage for seeds in late summer, fall, and winter. Numerous butterflies (30 species so far), bees, beetles, and other pollinators are active on flowers

blooming from April through October.  Even at night the meadow is alive with moths, beetles, and other insects and spiders.  Aiming a flashlight into the dense meadow plants, she can see the tiny, shining eyes of moths and other insects.  Bumble bees, too, sleep on the flower heads, resting for the next day’s work.

Edie has created a paradise for herself as well as the creatures that call her yard home. With binoculars and camera, she frequently takes nature walks around the yard.  The birds, whether eating, preening, feeding young, are always interesting.  Mating foxes are less expected.  Mating Garter Snakes, too. Even

better, she loves to discover a caterpillar eating leaves. When she locates other tiny creatures—bees, beetles, wasps, and others—she takes their photos.  At night she uses lights to attract moths.  She photographs these creatures, too.

Using the photos of insects, she can usually make identifications and then figure out their role in this ecosystem. What plants do they depend on?  What plants depend on them? What do they eat?  Who eats them?  Are they parasites?  Predators?

The possibilities for discovery are endless.  Mostly, she revels in success of the healthy ecosystem she has created.
