Daylilies were formerly counted among the Lily family, but they were given their own Daylily family, which was comprised of some twenty species. In the last re-shuffle two other families were combined to this to create the Grass Tree (Xanthorrhoeaceae) family, of which daylilies area a subfamily. As their name suggests, daylilies’ flower lasts only a day, but there are always new ones coming up to take over, so in this way it blooms for several weeks. Daylilies are native to eastern Asia, China and Japan. They are known to have been cultivated in Chinese gardens 2,500 years ago. They were not originally ornamentals, however, rather the young leaves and flowers were eaten as vegetables. The root and leaves were also used medicinally.

Daylilies are not known to grow ferally anywhere, but they seem to have originated from the Far East. The species arrived in Europe in the 16th century, and probably in Finland in the 19th century. Orange daylily has established itself in Finnish flower-beds and is especially common in old gardens. Old native varieties will happily grow from one year to the next in the same place with any need for re-planting or any other kind of care. The few fragile root shoots that are planted in the beginning can mature over the years to become a great abundance of leaves with dozens of flowering stems. Its leaves help it survive among weeds, but it cannot survive if the soil becomes too poor, as is often the case in old abandoned gardens.

Lemon Daylily & Citron Daylily (Long Yellow Daylily)

Hemerocallis lilio-asphodelus & Hemerocallis citrina

Lemon daylily (name also lemon lily or yellow day-lily) is the other popular daylily species. It has bright, pale yellow, fragrant flowers and narrower leaves than orange daylily. This perennial species is also easy to care for and thrives in rich, clayey ground, where its dense stands will gradually spread, even if all that is left of the garden it was originally planted in is a few mossy stones. Nowadays perennial flower beds are also filled with weaker varieties which disappear quickly without a trace if they are not looked after.
NOT TRANSLATED YET. Syyspäivänlilja on melko vaikea erottaa keltapäivänliljasta pelkän ulkonäön perusteella. Syyspäivänlilja on kuitenkin yökukkija ja sen kukat ovat erityisen tuoksuvia.
Tarhapäivänliljalajikkeita (H. Hybrida group) on lukuisia ja kukkien värit vaihtelevat valkoisesta monivärisiin.
