Fun Flower Facts: Daylily (Hemerocallis)


Although it has “lily” in its name, the daylily is not a member of the lily family (Liliaceae); it belongs to the Hemerocallis genus and is native China, Korea and Japan. The plant produces beautiful, showy trumpet-shaped flowers. There are thousands of cultivars available, ranging in colours, sizes and forms. Many of the cultivars are fragrant.  Plants can grow to be 6 inches to over 6 feet tall! The flowers will bloom from early spring to fall, depending on the variety.

The name daylily refers to the fact that the blooms will only lasts one day. The flowers typically will last no more than 24 hours, opening in the morning and dying within the night. As such, daylilies don’t make the best of cut flowers.

Despite its short life, daylilies are nicknamed the “perfect perennial plant” because they are one of the easiest and hardiest perennials around! Once they are established, they are essentially carefree and can survive the coldest of winters and the hottest of summers. Basically, daylilies are suitable for all landscapes and climates.

Plant in masses or as a ground cover on slope for the best visual impact. Grow in full sun or partial shade. Daylilies can also tolerate most soils, but do best in rich loam. Lighter, pastel colours shades, such as yellow, pink, will require a sunnier location to bring out their colours, while darker daylilies, such as some red and purple flowers, need shade because their darker colors will absorb heat.

    Our Daylily Miniature Mix provides a perfect variety of rainbow colored flowers for the daylily lover. Daylilies prefer a sunny location in northern zones, but will grow in partial shade with at least six hours of full sun. Hemerocallis prefer nutrient rich soil, and plants should be fertilized shortly after planting, in the early spring, and again in late summer. Daylililies do well in well drained soil, and prefer a heavy watering once a week rather than frequent light watering. Daylilies are prone to rotting if overwatered. In the fall, a layer of mulch on top of the plant will protect the root system, especially in colder northern climates.
