|Day-lily flowers are usually bright and showy, but they last but a single day.|
On Saturday, May 26, 2012, I stopped briefly at the garden of Robert Hopper and photographed several of the half dozen or so cultivars of day-lilies that he is growing. Garden day-lilies are derived from species of Hemerocallis, a genus native to Eurasia. One species with orange flowers, Hemerocallis fulva, is an extremely aggressive and invasive pest plant that has escaped from cultivation nearly throughout the United States and eastern Canada. A second species, Hemerocallis lilioasphodelus, with yellow flowers, is almost as widespread outside of cultivation, while Hemerocallis minor has escaped in Oregon. Due to their tendency to escape from cultivation and become invasive, gardeners should not cultivate day-lilies that regularly form seed pods or that form large vegetative colonies from underground rhizomes. Fortunately, modern hybrid cultivars have less of a tendency to become invasive since they usually do not readily form seeds and they commonly grow in better behaved clumps.
|This day-lily cultivar has cheery yellow flowers and is growing with the native Florida greeneyes (Berlandiera pumila).|
