What is a native plant?

The Arboretum's native plants are those species that have evolved on the Delmarva Peninsula over hundreds to thousands of years. They have adapted to grow in the local climate and soils and co-exist with the animals and other plants that occur here. Generally native plants are identified as those that existed here at the time of European settlement. The Arboretum plays an important role in protecting the health of the Chesapeake Bay by preserving and restoring the native flora of the region.

Why are native plants important?

Because native plants have evolved with the local fauna, they provide food and shelter for wildlife. Some butterflies and moths rely only on native plant species for food. Migrating birds depend on the rich berries of spicebush and viburnum. Oaks and hickories provide food for squirrels, deer, turkeys and many other animals. Plants are the base of the food chain, and by conserving these diverse flora we help to conserve the biodiversity of all life in the region. Plant communities also help to hold soil in place, to filter water, and to absorb pollutants. Native flora is beautiful and helps to make the region unique.
