Dormant, evergreen, and semi-evergreen refers to a daylily’s foliage.
- Dormant daylilies are deciduous.
- Evergreen daylilies, as the name implies, will retain their foliage through the winter.
- Semi-evergreen daylilies are in-between the two, with the overwintering of foliage dependent on climate.
As a general rule, those in warmer climates should stick with evergreen and semi-evergreen daylilies, while those in colder climates should have luck with both dormant and evergreen cultivars.
