Safety & Hazards

Large quantities of the leaves are said to be hallucinogenic. Blanching the leaves removes this hallucinatory component[1]. (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[PFAF].)

Cultivation Details

HabitPerennial
Growth—

Succeeds in most soils[2], including dry ones, preferring a rich moist soil and a sunny position[3] but tolerating partial shade[4]. Plants flower less freely in a shady position though the flowers can last longer in such a position[1]. Grows well in heavy clay soils. Succeeds in short grass if the soil is moist[2]. Prefers a pH between 6 and 7[5]. Hybridizes freely with other members of this genus[5]. This species is closely related to H. micrantha and H. plicata[1]. Individual flowers are short-lived, opening in the morning and withering in the evening, but the plant produces a succession of blooms over several weeks. Each scape carries between 75 and 100 blooms[1]. The flowers are smaller than most other species in the genus and are slightly fragrant[6]. Plants take a year or two to become established after being moved[5]. Plants seem to be immune to the predations of rabbits[7]. The plants are very susceptible to slug and snail damage, the young growth in spring is especially at risk[5].

Propagation

Seed - sow in the middle of spring in a greenhouse. Germination is usually fairly rapid and good. Prick out the seedlings into individual pots when they are large enough to handle. Grow the plants on for their first winter in a greenhouse and plant out in late spring[PFAF]. Division in spring or after flowering in late summer or autumn[5]. Division is very quick and easy, succeeding at almost any time of the year[PFAF]. Larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-21. <temperate.theferns.info/plant/Hemerocallis+multiflora>
