Can't remember

I got this at the Burleson RU, but I can't remember from whom or what it's called. Help, please.

Sybil, that is two-leaf senna (Senna roemeriana) for your wildflower/butterfly garden. http://www.wildflower.org/plants/result.php?id_plant=SERO8 I had the pot already sitting in water when I remembered I had not labeled it, and then I forgot to do so later.

Thanks, Patrob. I'm getting my tiller returned to me tomorrow (oh, these kids), and I plan to get my wildflower area ready next week. I'll go ahead and pot the senna, so it can mature a little before it goes into this hard clay. If I'm per usual, I won't get it done next week, but hey, gotta have a target, don't I?
