calla lillies

Question

My calla lillies unexpectedly sprouted and bloomed while wintering them in the basement. We are zone 4 and now I’d like to take them outside, but am not sure how to plant them because of the foliage and flowers.

Answer 1

Go ahead and plant them out as usual. The will be fine, just a little eager for warm weather, like the rest of use cold climate gardeners.
Shelter them just a bit, just like you are hardening off a new plant from the garden center--to help them adjust to the sun.
