WHAT IS MEANT BY DORMANT, SEMI-EVERGREEN AND EVERGREEN?
Evergreen daylilies keep their foliage all year round, there will be some natural turnover of leaves and it is a good idea to remove any dead leaves a couple of times a year. Semi-evergreen daylilies will loose some leaves in winter but not die down completely, so you can always see where they are. The degree of leaf lose will vary with the cultivar and climate. It often will be barely noticeable. Dormant daylilies will loose all their leaves in late autumn and then come away with lovely fresh foliage in spring.
