Hemerocallis lilioasphodelus, commonly known as the lemon daylily, yellow daylily, or custard lily, is a species of flowering plant in the family Asphodelaceae. It is native to Asia, particularly found in areas of China, Korea, and Japan. This perennial plant is well-regarded for its ornamental value in gardens and landscapes across the world.

Description

Hemerocallis lilioasphodelus grows to a height of 60–90 cm (24–35 in). It forms clumps of arching, blade-like leaves that are green in color. The plant produces tall scapes, which are leafless stems, that bear clusters of fragrant, trumpet-shaped flowers. The flowers are typically a bright lemon-yellow color, about 5–8 cm (2–3 in) in diameter, and bloom in early to mid-summer. Each flower lasts only for a single day, hence the name "daylily," but the plant produces many buds that open on successive days.

Cultivation

This species prefers full sun to partial shade and thrives in well-drained soil. It is tolerant of a variety of soil types and conditions, making it a versatile choice for gardeners. Hemerocallis lilioasphodelus is also known for its drought resistance once established, making it suitable for xeriscaping. Propagation is typically done through division of the root clump, ideally performed in early spring or after the plant has finished flowering.

Uses

Beyond its ornamental use, the flowers and buds of Hemerocallis lilioasphodelus are edible and have been used in traditional Chinese cuisine. They can be added to salads, soups, or used as a garnish, providing a mild, sweet flavor. In traditional medicine, parts of the plant have been used to treat conditions such as insomnia and inflammation, although scientific evidence supporting these uses is limited.

Conservation

While Hemerocallis lilioasphodelus is not currently listed as endangered, its natural habitats are under threat from urbanization and agricultural expansion. Conservation efforts are important to preserve its wild populations and the biodiversity of the regions it inhabits.
