Prime Plants for Nature: Backyards for Nature 2015 Native Plant Awards

By Edie Parnum

Each year we select two native plant species with exceptional ability to support wildlife.  These plants will contribute significantly to the web of life in your yard.  They host insects, offer nectar and pollen, and produce fruits, seeds, or nuts.  Birds, butterflies, and other insects and animals will feed and prosper.  The Prime Plants will provide shelter and nesting places, too.  Our selections, all native to southeastern Pennsylvania, are easy to grow and will make attractive additions to your landscape.  They are readily available at native plant nurseries or native plant sales. We offer awards in two categories: Trees and Shrubs and Perennials.

Our selections for the 2015 Prime Plants for Nature Awards are:
