Here are several native plants sale here in the Philadelphia and Mid- Atlantic area. In Season also has a full list of native plant sales in the Mid-Atlantic region.
When I attend native plants sales, I find it helpful to take a native plant list with me. I make a list of the plants I have researched and decided to add to my garden. This cuts down but doesn’t eliminate impulse buys. My favorite native plant garden guide for the Mid-Atlantic is Native Plants of the Northeast by Donald J. Leopold along with other books on my list of best books.

Red Bud Native Plant Nursery
Red Bud sells only Mid-Atlantic native plants. I go there a drool. It is the place for flowers, shrubs, ferns and other native plants.

Octororo is wholesale only and sells through environmental centers, plant nurseries and plant sales throughout the region. http://www.octoraro.com
