Facts About Daylilies


The daylily is a widely grown perennial flower that blooms continuously through the spring and summer months. Its botanical name is Hemerocallis, which means "beautiful for a day." The name reflects the reality that daylilies’ blooms last for only one day.


  • Of the approximately 32,000 registered daylilies, more than 12,000 types are available commercially, according to Iowa State University Extension. Daylily plants have arching foliage that grows 1 to 2 feet long and flower stalks known as scapes, which spring from the crown of the plant and range from 18 inches to 5 feet tall. Most daylilies are deciduous.


  • Daylilies are planted in borders and flower beds and are used to bind slopes. The plants may produce flowers in a wide range of colors, including yellow, white, pink, orange and purple. The diameter of the flowers ranges from 2 inches to 8 inches.


  • Daylilies require full sun and well-drained soil enriched with organic matter to bloom well. They need a 10-10-10 fertilizer just once a year—in early spring. Feeding too much causes excess foliage and no flowers. Daylilies need weekly watering when there is no rainfall. Mulching with wood chips, grass clippings or shredded leaves is also recommended.
