Can anyone tell me how to distinguish between seedlings of mimosa trees (hardy silk) and sunshine mimosa? Both plants grow wild and prolifically in my woodsy neighborhood, but I can't tell one from the other at the seedling stage. I am constantly pulling seedlings from my yard -- hundreds of them -- but i can't tell what's what. Someone here was looking for sunshine mimosa; maybe others would like the hardy silk. If I could be sure that what I'm pulling is what people are wanting, I would have a lot to offer. (:-)
