Individual daylily flowers open for one day, but the numerous flowers produced per stem extend the blooming period to three to four weeks. In addition, a plant will produce several stems with flowers. Reblooming daylily cultivars bloom throughout the summer and up to frost.
Daylilies have trumplike flowers.
The wide assortment of flower colors includes pale cream, white, pink, purple, yellow, gold, orange, red and maroon. Some cultivars have flowers with one color for the throat, which is inside the center of the flower, and another color for the petals. The petals of the flowers may have different characteristics. The edge of some petals are daintily ruffled, while others are heavily ruffled and gathered. Still others have smooth edges.
