As their name suggests, these beautiful flowers bloom for only one day, but the sheer delight of their colours and size make them a beautiful feature in the summer garden. The botanical name Hemerocallis is derived from the Greek words for ‘beauty’ and ‘day’, emphasizing its shortlived sensation.

Native to meadows in Asia, a few species have become naturalized in Europe and North America, and thousands of cultivars and hybrids are available, ranging in numerous colours, shapes, sizes and flowering times. These popular perennials vary in size from 60 cm to 2 m, although most are less than 1 m.
Fun fact | Daylilies are edible! A popular ingredient in Chinese and Korean cuisine, daylily flower buds are used to flavour stews and soups.

Daylilies are so easy to grow and continually produce flowers throughout the warm season to add colour and interest to your garden. One of their many attractions is their adaptability. These flowering beauties can grow in sun or partial shade and don’t need much special attention but do grow best in moist, fertile soils in sunny positions.
Daylilies are not only waterwise but also drought-resistant, and, depending on the variety, able to tolerate frost. Daylilies can be dormant, evergreen or semi-evergreen. Dormant varieties die back in winter whereas semi-evergreen varieties partially recede, except in warmer climates.

In South Africa, daylilies have their peak flowering time in November to mid-January. Be sure to select early, midseason and late-blooming varieties to give you an extended flowering period throughout the summer months.
Whether planted en masse, in perennial borders or in a container, daylilies make an immediate impact in any setting. Plant them as groundcovers or combine them with roses, or other perennials like Bearded irises, lavender, Shasta daisies and Buddlejas, for a colourful display.

Daylilies also make for beautiful, short-lived cut-flowers.

Growing daylilies

Give your daylilies a good start by digging plenty of organic matter into the soil before you plant them and add a layer of organic mulch once established. Apply a low-nitrogen fertiliser in spring to encourage flowering. During the flowering season, deadhead regularly to keep the plant neat.
Tip | Plants grown in sun produce more flowers than those grown in the shade.
Daylilies reproduce by forming clumps and, after a few years, can become overcrowded resulting in fewer flowers. If you find your daylilies are becoming congested, dig the plant up, divide and replant in fresh soil. Daylilies can be divided at any time of the year, but best is after flowering.
