Dennis, give it a try! So far so good with mine in the buckets! I know that this isn't going to be their permanent residence, but it is working great for now. None of them have bloomed this year, but I wasn't expecting them to after being yanked out of the ground and scolded.
I know nothing about growing them, so I just hope they survive until I can get a better spot to put them in the ground. At least for now, I've got more daylily room!
