Nope, I do not think it is a Digitalis. The seed pods are so very different.

Michael, it looks like Rattlebox, a native and yes it's pretty but it's deadly poisonous to livestock. We have some here.

Thank you. That makes sense, the brown pods do rattle. Luckily there are no livestock near us and my dogs have never tried eating plants. Still, if they germinate, I will plant away from where the dogs go.

Crotolaria. They used to plant it as a cover crop in SC, and it escaped everywhere. You should see an whole field of it. So pretty, but really useless. They would plow it under before it went to seed.

The kind they plant as a cover crop is a different variety or species, I think. It's called Sunn Hemp.

This is an interesting article about it

Hmm. So it is a non-native invasive that is being held in check by a moth. Well, I could say, 'I will just remove the seed pods and keep it from spreading, but I think it would kind of be a smack in my own face considering I like to keep my yard mostly native and completely Florida Friendly. I will stash the pods I have until my next biochar burn and add them to the inner retort chamber. Could make for some interesting looking carbon coals.

I didn't realize some of them are invasive. When we had the Extension Service talk about poisonous plants to livestock, they mentioned it and said it was a native, maybe the one they were talking about is. All I know is when I catch it seeding on my property I get rid of the seed pods. I don't have livestock but I have neighbors that do. There are a lot of plants growing wild in FL that are bad for livestock, Lantana, Wild Cherry, Johnson Grass, all of which are everywhere around here.

Yep. We do have two natives, but they are low growing. The tall varieties with apikes of flowers are the invasive ones. Just my luck that I find one of the invasive ones.
