Orange daylily is a popular ornamental that has escaped to invade natural and disturbed areas throughout the United States. Plants are 2-4 ft. (0.6-1.2 m) tall with round stems. Leaves are grass-like, bright-green, 1-3 ft. (0.3-1 m) long and curve toward the ground. Flowers develop in the summer and are large, showy, and orange in color. Flowers occur in clusters of 5-9 at the apex of the stalk. Flowers in a cluster open one at a time and only for one day each. Flowers may have spots or stripes. Many cultivars of daylily now exist in a wide variety of sizes and flower colors. Orange daylily infestations often occur adjacent to plantings or at old homesites. Areas invaded include meadows, forests, floodplains, ditches, and forest edges. Once established, the thick tubers make control difficult. Orange daylily is native to Asia and was introduced into the United States in the late 19th century as an ornamental. |
