Divide the plants, as cultivars do not come true from seed. When they become overcrowded, begin to flower less, or in the early spring or early fall, you can divide.

The entire plant is edible, and flowers can be safely used as a garnish or in salads.

Daylilies are hardy, long-lived perennials. They like full or partial sun, and will turn to face it.

The funnel-shaped blooms last for only one day, but new blooms continue for weeks or months from late spring through the summer. The flowers bloom on tall stalks, starting at the top. When used as cut flowers, a single bloom will fade after one day, but the other buds will flower on subsequent days.

Daylilies do best in rich, fertile, moist, well-drained soils, but some cultivars can grow in sandy soil as well. Keep soil moist during dry weather for better blooming.

Once established, you can fertilize the plants lightly, with a mix low in Nitrogen. Use mulch in the summer to help retain moisture and regulate the soil temperature.

Remove the top of the stalk daily, to the point of the spent flower. In the autumn, cut back to the ground.

Beware slugs and snails which will leave the foliage unsightly. Aphids, thrips, spider mites, and hemerocallis gall midge can also cause problems. In areas with high humidity and temperatures above 90F, crown rot becomes a major issue. After a cold winter of freezing and thawing, bacterial leaf and stem rot can occur in the spring.
