Hemerocallis exaltata (1 Page of 5) The Hemerocallis exaltata plant species is found in E. Asia - Japan, it is only found on Tobishima Island, a small Islet off W. Japan. It is a member of the Hemerocallidaceae family. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Hemerocallis exaltata Family: Hemerocallidaceae Author: Stout. 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: 1 Mature Width: 0.45 Habitat: Meadows[187].
Cultivation Notes: Succeeds in most soils[1], including dry ones, preferring a rich moist soil[200, 205]. Grows well in heavy clay soils. Succeeding in sun or shade, it produces more flowers in a sunny position though these flowers can be shorter-lived in very sunny positions[205]. Succeeds in short grass if the soil is moist[1]. Prefers a pH between 6 and 7[200].
This species is hardy to about -15°c[187].
Hybridizes freely with other members of this genus[200].
Some roots are short and enlarged, others long with spindle-shaped tuberous ends. The plant forms a compact clump[233], but it also produces rhizomes that tend to spread[205].
Individual flowers are very short-lived, they open in the morning and wither in the evening[205].
Plants take a year or two to become established after being moved[200].
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].
