Once grouped with the true lilies, this small genus of 15 species of fleshy-root perennials from temperate East Asia is now the type genus for its own family, the Hemerocallidaceae. The plants form clumps of grassy or irislike leaves with funnel- to bell-shaped flowers held aloft on sturdy stems. Flowers come in a variety of forms and in shades of warm yellow, apricot, red and mauve. Individual flowers last only a day-hence the common name of daylily-although the plants do produce a succession of blooms lasting from late spring until autumn. All parts, especially the buds and flowers, are edible and may be added to salads or used as a colorful garnish. Stamens can be used as a saffron color substitute.
CULTIVATION
Hemerocallis plants are hardy and are easily grown in a sunny or partly shaded position with fertile, moist, well-drained soil. The flowers turn to face the sun, which is an important consideration when positioning the plants in the garden. Propagation is usually by division.
Top Tip
Every few years it is a good idea to lift and divide clumps of daylilies as this will help to maintain vigor. Evergreen daylilies should be divided in spring.
