A number of places are hosting native plant sales this weekend in Pennsylvania. I'll be stopping by the Yellow Springs Nursery for some natives and artisinal goat cheese. I was at Bowman Hill last weekend, just for a walk and saw some really beautiful stuff. The Trillium were in full bloom, the lady's slippers were budding out, it's a great place to visit and their native plant sale is tops in the area.
Here is a list of the sales going on.
