I bought a couple tropical lilies this spring and put them into a couple 300 gallon Rubbermaid ponds (one in-ground and one above ground). They were very healthy plants when they arrived the first week of June. They both had about 6 leaves. Well, we've had much lower than normal temps here in central Indiana and their leaves are sort of dying off with very little new growth coming. Will they start back up when (if) it ever heats up again? My hardy lilies are handling the temps fine, but these tropicals are struggling. Hopefully they just went back to sleep for awhile.

Do you think they will rebound?

Thanks.
