Native Vines for Beauty and Wildlife Value

 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.

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, 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.

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.

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.

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.

My Hummingbirds

By Edie Parnum

I watch my Ruby-throated Hummingbirds obsessively.  Beginning in early May flashes of iridescent green zip around my yard.  These tiny sprites hover, fly straight up, down, and even backwards. When the light is just so, I can glimpse the male’s dazzling red gorget.  I’ve seen that red innumerable times, but I’m always mesmerized.

When I hear a zippety-tzit sound, I know that my territorial male is chasing another hummer away from the flowers or feeders. My male often watches for competitors from his favorite perch, usually a small, but conspicuous, horizontal branch.  Like other hummers, he uses a perch to watch for tiny flying insects (an important source of protein), then snags them in mid-air.  On occasion I’ve seen the resident male dive up and down in a pendulum swing for the benefit of a female.

I refer to them as “my” hummingbirds, but they’re not mine at all.  True, they feed at my feeders, which I assiduously clean and fill with fresh sugar water every few days.   They visit the flowers I’ve planted for them–Trumpet Honeysuckle, Trumpet Vine, Bee Balm, Cardinal Flower, Great Blue Lobelia, and Wild Columbine.  Ruby-throats are not particularly shy, sometimes feeding or hovering just a few feet from me.  Once, a hummer tried to get nectar from a pink flower on my shirt.  Another time when one fed just a few feet in front of me, I could see its hyper-fast heart beats (1200 beats per minute while feeding). Nevertheless, most of their lives are unknown to me.

Female nectaring on Trumpet Honeysuckle

Even though I watch intently, I catch only brief glimpses.  Often one will zip behind the deck railing or some leaves, where my view is obscured. Or it simply vanishes.  I try to count the number in my yard.  I can usually spot two or three, but know that there are probably more during midsummer.  I’ve never seen a pair mate.  I’ve never seen a female build a nest, incubate eggs, or feed nestlings in my yard.  After all, they are wild creatures and don’t live their lives for my amusement.  They elude me.

Soon my resident hummingbirds will be gone. Because the adult males take no part in raising the young, they start migrating in the latter part of July.  The local females and young soon follow. During August and September the hummingbirds I see in my yard come from the north.  I persist in thinking of these migrants as mine, too, since hummingbirds evidently use the same stop-over feeding areas year after year.

Female Ruby-throated Hummingbird

Usually I don’t see any hummers in my yard after the third week in September.  By then, I no longer have illusions of ownership. I won’t see them on their non-stop 600-mile trip across the Gulf of Mexico.  And only if I take an unexpected trip to southern Mexico or Central America will I see them during the winter months.  More likely I’ll be deprived of hummingbirds for seven months.  However, I’ll welcome my hummingbirds back to my yard next spring—indeed, some will be the same birds.
