Why native plants?
As a Master Gardener I've gradually learned more about the role of our plant choices in providing habitat that is being lost at alarming rates. Though our part of the world often looks very green, the diversity and quality of habitat is in decline. Most of our wooded areas, for example, are full of invasive species replacing the native undergrowth. If each of us tries to plant natives -- canopy trees, understory trees, shrubs, perennials and groundcover -- we can help mitigate native plant losses. --Merikay
Why plant a native tree? Here's just one example. The native dogwood (Cornus florda) supports 117 species of native moths and butterflies. The Asian dogwood (Cornus kousa) supports no native insect herbivores (from Dr. Doug Tallamy, University of Delaware entomologist). Often there are very complex relationships between plants and insects, birds and other animals. When a native plant is no longer growing in an area, creatures dependent on that plant are also lost. The web of life unravels.
Match the right plant to the right place.
If you have a space that is small or large, shady or full sun, soggy or dry there's a native plant that can and will take root if you give it a chance. From trees (large and small), shrubs, perennials, vines, ground covers, these plants will fit the conditions of the area because they are adapted to the weather, pests, soil, and seasons of Eastern North America. They provide habitat for insects and other creatures which have co-evolved often over millions of years in intricate relationships. This is why replacing extensive areas of non-native turf grass with native plants can be so beneficial. A mix of native and non-native plants, particularly if they are diverse, can also be a practical, beautiful and life-providing alternative to turf.
Reduce lawn by adding or extending beds. Remove invasive plants. If you have woods, increase native understory and ground cover and add native shrubs and perennials at the edge.

Some Native Plant Sources
Local nurseries: Plants tagged as native may not be locally native, check. Ask for the source of the plant. Buy nursery propagated vs. nursery grown (may have been wild collected). Don't collect from the wild yourself unless the area is going to be destroyed and plants need to be rescued. Most plants don't survive being transplanted.
