* Outside zones 3 to 9, the hardiness range our sources give for daylilies. Plants there may not survive the winter or get enough winter chill, and are usually grown as annuals or in pots.

Where frost is rare

In Florida daylilies can go in the ground in any month, but spring and fall plantings succeed best. In central and south Florida, choose evergreen types, because dormant (deciduous) types may not get enough winter chill to grow and flower well. Florida bloom starts around March for early cultivars and mid-May for late ones.
