Uses

Toxicity

Toxicity warning. The historical record reports a hazard for this plant. Do not use it to decide which parts are safe to eat or use medicinally.

This section contains historical Plants For A Future notes marked noncommercial.

Large quantities of the leaves are said to be hallucinogenic. Blanching the leaves removes this hallucinatory component[4]. (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].)

Edible uses

This section contains historical Plants For A Future notes marked noncommercial.

Leaves and young shoots - cooked[4]. They must be consumed when very young or else they become fibrous[K]. Flowers and flower buds - raw or cooked[2]. The flowers can be up to 12cm long[4]. The flower buds contain about 43mg vitamin C per 100g, 983 IU vitamin A and 3.1% protein[4]. If this species has swollen roots then they can be eaten raw or cooked.

Propagation

This section contains historical Plants For A Future notes marked noncommercial.

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[K]. Division in spring or after flowering in late summer or autumn[3]. Division is very quick and easy, succeeding at almost any time of the year[K]. 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.

Cultivation

This section contains historical Plants For A Future notes marked noncommercial.

Succeeds in most soils[1], including dry ones, preferring a rich moist soil and a sunny position[4]. 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[4]. Succeeds in short grass if the soil is moist[1]. Prefers a pH between 6 and 7[3]. According to the Flora of China, this species is no more than a synonym for H. citrina[6]. It is, however, seen as a distinct species in other treatments and so is maintained here as a separate species[K]. This species has not yet been grown in Europe (1994) so its hardiness is not known[4]. Hybridizes freely with other members of this genus[3]. Individual flowers only live for one day, however there are 50 - 80 flowers produced on each scape[4]. Plants take a year or two to become established after being moved[1]. Plants seem to be immune to the predations of rabbits[5]. The plants are very susceptible to slug and snail damage, the young growth in spring is especially at risk[3].
