Common Daylily
COMMON NAME:
Common daylilySCIENTIFIC NAME:
Hemerocallis fulvaORIGIN:
AsiaDESCRIPTION:
Daylilies produce clusters of 5-9 large, showy orange flowers. Each individual flower exists only for one day. The flowering stalks grow 2-4 ft., while the long, grass-like leaves will grow to be 1-3 ft. long. Daylilies will spread through rhizomes, and will grow in dense clumps.HABITAT:
Introduced in the 19th century as an ornamental, and valued for being adaptable and “low maintenance”, daylilies are able to thrive in a variety of habitats. They can be found in human-dominated sites such as abandoned fields and roadsides, but will also invade natural habitats such as forests and meadows.THREAT:
Daylilies spread rapidly, producing clones through rhizomes. They form mats of tubers below ground and dense foliage, preventing any native plants from sprouting within a daylily patch.MANAGEMENT:
Daylily patches can be dug out of the ground. All the tubers must be removed and disposed of in a landfill. Herbicides may also be used through foliar applications.
