Add a perennial home improvement — Plant Daylilies! Vigorous, carefree and colorful, these daylilies have been developed for their vibrant long-lasting color. In the individual copy, we have indicated which varieties are evergreen, semi-evergreen
and dormant. An evergreen variety's foliage will remain and the plant will not go into a dormant stage, which makes it more susceptible to damage from frost. A light mulch on top of the foliage will protect the plants from this damage. Semi-evergreen
varieties will lose some of their foliage and will go into a dormant stage, and usually do not require any mulching. The hardiest daylilies are those varieties that go completely dormant during the winter.
