Hi Sandra, this may be a bit of a trek from Lagrangeville, it is for me too, but I find it worth the trip once or twice in a season. Friendly, unassuming place with great selections of native plants, including water plants. Here's the url of their web site:
Firstly, what is your deer situation? Deer have eliminated a lot of our native plants and are going to destroy almost everything you plant unless you stick to a few things they hate - and that doesn't always prevent deer damage. The ecology here has changed drastically since deer have moved in and a lot of our choicest natives have been grazed out of existence. If you are not going to protect against deer, you are fighting a losing battle. I found that out the hard way when I tried to plant our native wild azalea - it never had a chance.
I attended the WCC native plant sale but most of the perennials were gone during a pre-sale.
I also went to the Catskill Native Nursery and they had a diverse selection of perennials, trees and shrubs. I was intrigued about American wisteria (which they are getting in soon) so I have to think where it might go on my property. I have two acres and just about all conditions: shade, part sun, and all day sun. The only condition that is usually absent for long periods is wet.
