Summary

The yellow-flowered H. dumortieri is a vigorous, clump-forming plant and one of the first species to flower in early summer. H. middendorffii is an herbaceous perennial growing to 0.9m. It has linear arching leaves with golden yellow or orange flowers that are slightly fragrant. It can grow in semi-shade (light woodland). Edible Parts include the Flowers and Leaves. Medicinal Uses include: Antidote; Diuretic. Other Uses include: Weaving. The tough dried foliage is plaited into cord and used for making footwear. Hemerocallis species, Daylilies are a flowering plant in the genus Hemerocallis. The flowers are usually large and showy, with six petals. They come in various colours: yellow, orange, pink, red and purple. The daylily is native to Eurasia and is found in many parts of the world. The flowers typically last for one day, hence the name ‘daylily’. They are straightforward to grow, with many forms tolerant of almost total neglect. Daylilies are widely used as a food crop in China and Japan. The genus comprises about 20 species. The Common DayLily H. fulva is more heat tolerant and grows well in drier climates. All parts of the plants are edible, with the flowers used more frequently. Eat the flowers raw when fully open. The petals are thick, crisp and juicy, with a delicate sweetness at their base due to their nectar. They are nutritious, containing reasonable quantities of protein, carbohydrates, iron and vitamin A. They are a great addition to the salad bowl. Cook flower buds; they taste like green beans. In the Orient, the flowers are dried and used as a flavouring and thickener in soups and sauces. The young shoots have a pleasant sweet flavour, making an excellent cooked vegetable. Depending on the species, young shoots are harvested from late winter and for much of the spring. Many species also produce edible nutty-flavoured young roots eaten raw or cooked. Many Hemerocallis species are excellent weed-excluding ground cover, succeeding under and around trees and shrubs. Plant clump-forming species such as H. dumortieri, H. lilioasphodelus and H. middendorffii 50cm (18in) apart. Running species such as H. fulva are planted up to 1m (3ft) apart. Form: Irregular or sprawling. Bloom Color: Yellow. Main Bloom Time: Early fall, Late summer.

Antidote  Diuretic  Vitamin C

The juice of the roots is an effective antidote in cases of arsenic poisoning[205]. A tea made from the boiled roots is used as a diuretic[205].

Other Uses

Weaving

The tough dried foliage is plaited into cord and used for making footwear[205]. Plants form a spreading clump and are suitable for ground cover when spaced about 45cm apart each way[208]. The dead leaves should be left on the ground in the winter to ensure effective cover[208]. (This report was for a plant labelled H. middendorfiana, which I have assumed is a mis-spelling of this species[K]). Attractive flowers. 1. Nectary - Flowers rich in nectar and pollen: Yes – Daylilies produce abundant nectar, attracting various pollinators, including bees and butterflies. 2. Wildlife - Food (Fruit, Seeds, Leaf litter, Shelter, Nesting, Roosting): Yes – The flowers and young buds of daylilies are edible and can be consumed by both humans and wildlife. The dense foliage can provide some shelter for small wildlife, though they are not typically used for nesting. 3. Invertebrate Shelter (Overwintering sites, Leaf litter, Groundcover): Yes – Daylilies can provide ground cover and some overwintering habitat for beneficial insects, particularly in their leaf litter. 4. Pest Confuser (Smell): No – Daylilies do not have a strong aroma that would effectively confuse pests.

Cultivation details

Landscape Uses:Border, Container, Ground cover, Massing, Seashore. Succeeds in most soils[1], including dry ones, preferring a rich moist soil and a sunny position[111] but tolerating partial shade[88]. Plants flower less freely in a shady position though the flowers can last longer in such a position[205]. Grows well in heavy clay soils. Succeeds in short grass if the soil is moist[1]. Prefers a pH between 6 and 7[200]. Hybridizes freely with other members of this genus[200]. Individual flowers are short-lived, but the plant produces a succession of blooms and also flowers again in late summer[205]. The plant has a fibrous root system that does not extend far[205]. Plants take a year or two to become established after being moved but then form large clumps[200, 187]. Plants seem to be immune to the predations of rabbits[233]. The plants are very susceptible to slug and snail damage, the young growth in spring is especially at risk[200]. Special Features: Attractive foliage, Not North American native, Naturalizing, Attracts butterflies, Suitable for cut flowers, Fragrant flowers.

Plant Propagation

Seed - sow in the middle of spring in a greenhouse. Germination is usually fairly rapid and good. Prick out the seedlings into individual pots when they are large enough to handle. Grow the plants on for their first winter in a greenhouse and plant out in late spring[K]. Division in spring or after flowering in late summer or autumn[200]. Division is very quick and easy, succeeding at almost any time of the year[K]. Larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.
