Daylilly : Hemerocallis

One of the most diverse groups of perennials with more than 34,000 types available in the US. Single or double flowers of almost every color appear in succession through the summer, each fading after 1 day. Easy-to-grow, heat- and drought-tolerant, use in dry or water gardens, containers or mass on slopes. New varieties are always being introduced, some of dwarf height, with more intensely-colored flowers, more vigorous growth or longer blooming seasons. Some are semi-evergreen. In China, the buds and dried flowers are an edible delicacy.
Remove old flowers daily to prolong bloom. Don't over-fertilize as more foliage than blooms appear.
