I have an area in my garden that I really don't plant in. I think I'll do it up in milkweed. I adore butterflies and they seem to love my morning glories. I do appreciate the heads up on this.
I just ordered from that site. Very easy to do. I like the idea that I can order and have them donate half to folks who can't afford them. Help the butterflies AND the people. Nifty!
