Daylilies are classic, extremely popular garden plants. They feature long, arching, strappy leaves and long stems of generally 6-petaled flowers, though double flowers are popular as well. Each flower lasts only one day, hence the plant’s common name. Daylilies come in a wide range of colors, from cream and cheery yellow to peach, orange, fiery red, deep burgundy, pink, and purple. Some have contrasting throats and "eye-zones." Daylilies are ideal for a mixed herbaceous perennial border.

This pale-yellow-flowered daylily distinguishes itself with its profuse bloom and compact size (only 16 inches tall), making it good for containers and the borders. It is an early season bloomer with circular flowers that open in late afternoon and last through the night.
