General Description

A wild species of daylily with a tremendously expansive native range, the yellow daylily is elegant but simple in its midsummer flowering season. Native to easternmost Europe all the way to China, Korea, Japan, Mongolia and Siberia, this herbaceous perennial grows into a clump of rope-like roots and long, arching green leaves. In mid- to late summer, upright flower stems - called scapes - grow barely as high as the mound of foliage. Six petal-like tepals comprise the flower that is fragrant. While most other wild daylily's flowers last no more than 24 hours, this species' blooms last one to three days. The scape tip bears flower buds that first open in the mid- to late afternoon. Plants die back on the return of frosty fall weather.

Grow the yellow daylily in any fertile soil that is average to well-drained. Full sun promotes the best flowering display, but partial shade is acceptable. Cut off the old flowers to tidy the flower clusters, and cut back the scapes once the season is over. Plant the daylily in a mixed border or meadow or massed as a tall, billowy groundcover. In China, this plant's flowers were traditionally steamed and dried to eat later.
