Yellow Daylily

Hemerocallis lilioasphodelus, the yellow or lemon daylily, is a spreading perennial with narrow, bright green leaves and fragrant, lemon-yellow flowers. The flowers open in the afternoon and last for a day, bringing scent close to paths and entrances in an early-flowering season.

It suits sunny mixed borders and can be planted in drifts; the foliage may remain semi-evergreen in mild areas. A plant can reach about 1 m tall, and its rhizomatous growth benefits from room to form a clump.

Water regularly in spring while buds form, especially during dry weather. Daylilies are adaptable, but prolonged drought can reduce bloom.

Clear dead foliage when it becomes untidy, then divide the clump about every three years in spring to maintain vigor.
