Rob,.....try Octararo Nurseries, who grows purely native plants for large scale restoration projects. They are wholesale but will usually sell big orders to landowners.
Thanks for that tip Jeff. Octoraro Nurseries is less than 15 miles from my property. I knew they were wholesale only and figured they wouldn't sell directly to me. I have a friend who is a part-time landscaper that may be able to buy from them. However, I like your idea better and will conctact them directly. They have most of what I need and their inventory and prices are on-line.
The area I want to plant is about 15-20,000 sq ft and varies from really wet to moist to sometimes moist and is partly shaded by some large trees. I have been clearing out the invasive plants, vines and sticker bushes. I'd love to be able to plant some of these bushes and let them take over.
