Kent, you're right, it's baptisia. I had moved that plant to another location, and I must have missed some, as it came back. Oh well, it must like it there.
Brad, I don't know if I sent you any of those two or not, but I had a huge clump of Mexican Holiday that I dug up. I moved two rhizomes to a new bed, and got rid of the rest. It's a good grower. If not, I will get some to you next summer.
