Compare your seedling to Gleditsia triacanthos, honey locust.

Jeanne, I did some research on the Goog and I really don't think these seedlings are Gleditisia triacanthos, Honey Locust. It took me a while but, I finally found a honey locust seedling image to view. They don't look the same. The honey locust doesn't have those little pointy things at the tips of the leaves like the ones I have pictured. It's probably going to turn out to be some type of weed. I shoveled some soil in that bed that came from the woods across the street. There must have been some seeds in that soil. I've spent a lot of time in the woods for the past month or so trying to clear out ivy, honeysuckly & wild grape vines. I haven't run across any plant or tree that has a mimosa-type leaf.

Jeanne, you're a trooper for trying to help me and I thank you so much. You're tops in my book!!!

Senna herbacea or similar species.

Thanks to your lead, Saltcedar, by accident I ran across the Virginia Tech website and believe I have an answer. It seems that my little seedlings are some type of Hemp Sesbania. The plant has a pretty bloom. Once again I'm not familiar with this plalnt and still am not sure if it's a weed or wildflower. I'll keep looking on the web. Anyway, I'm pretty sure this is Sesbania.

Jeanne & Saltcedar, thank you so much for your help. I really appreciate it.

Bon
