Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Hemerocallis thunbergii Family: Hemerocallidaceae Author: Bak. Known Hazards: Large quantities of the leaves are said to be halucinogenic. Blanching the leaves removes this hallucinatory component[205]. (This report does not make clear what it means by blanching, it could be excluding light from the growing shoots or immersing in boiling water[K].) Mature Height: 0.5 Mature Width: 0.5 Habitat: Mountains in C. and S. Japan[58].
Cultivation Notes: 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].
Plants take a year or two to become established after being moved[200]. They increase by means of runners[205] and form loose spreading clumps[K]. The roots are not swollen[233].
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].
The fragrant flowers are very short-lived, they open in the late afternoon and die in the morning[200, 205]. However, plants produce a succession of flowers for several weeks of the summer, each scape carrying between 4 and 20 blooms[205].
