Growing daylilies (Hemerocallis) has been a pleasure for gardeners for centuries. From the 15 or so original species found in the Orient and Central Europe, we now have approximately 35,000 hybrids from which to choose and more are coming every year. Older, traditional plants die back during winter, but there are new semi- and evergreen varieties. While their beautiful flowers last only one day, a mature clump can produce 200-400 blooms over the course of a month or more. Planting daylilies as single specimens or en masse as a ground cover for a slope, these lovelies will make a welcome addition to any garden, but are of particular joy to the weekend gardener who simply doesn’t have time for fussier plantings. Caring for daylilies is so easy and these plants are so hardy, that some seem to even thrive on neglect!
