This term refers to the winter behavior of daylily leaves. A hybridizer will register a cultivar as either dormant, semi-evergreen or evergreen. This indicates how the cultivar's foliage passes winters in the hybridizer's garden, but is not necessarily an indication of how it will behave elsewhere under differing environmental conditions. Note that hardiness and foliage habit are inherited separately, thus not all evergreens are tender and not all dormants are hardy. |
