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.
