min. spring temp for calla lilys?

Denver, CO(Zone 5b)

Any one have any suggestions? I have some that are just getting too big for their pots, Im sure the ground wont freeze anymore, but we may get one or two more frosts.

I divided mine in mid-February, which is probably close to the temps you're having now. They're thriving, especially with the addition of some coffee grounds and the rain we've just had.

Just put something over them if it's going to be cold enough to frost. Mine stayed in the ground in TN all winter and didn't freeze.

Mine are blooming in the greenhouse. I think it is time for them to go outside.
