Daylilies belong to the genus Hemerocallis and are not true lilies. The name is appropriate since each flower lasts only one day. There are more than 35,000 registered daylily varieties (cultivars) on the market today.
Each daylily plant produces an abundance of flower buds that open over a long period. There are many varieties, a wide range of flower colours, and the flowers continue blooming during the summer.
Plant daylilies in full sun for the most blooms. Daylilies tolerate just about any well-drained soil, but use lots of organic matter before planting for optimal results.
