I pulled these from a rent house we were renovating, stuck in in our beds at home and they flourished. I put them in pots this Feb. for the transpo, gave them a little more sun than they had, and they're all blooming like crazy. Any help with an ID, please? Once they multiply enough in the new place, I can add them to my trade list in small doses.

Really, I am so ignorant about them that I first posted this in the Lilies forum, so any help is appreciated. If I don't respond right away with thanks, it's because we're painting and moving this week. But thank you in advance!
