Uses

Toxic parts

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[K].)

Edible uses

Notes

Leaves and young shoots - cooked[2][3]. They must be consumed when very young or else they become fibrous[K]. Flowers and flower buds - raw or cooked[1]. The flowers can be dried and used as a thickener in soups etc. The flower buds contain about 43mg vitamin C per 100g, 983 IU vitamin A and 3.1% protein[1].

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[K]. Division in spring or after flowering in late summer or autumn[4]. 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

Succeeds in most soils[5], including dry ones, preferring a rich moist soil and a sunny position[6] but tolerating partial shade[7]. 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[5]. Prefers a pH between 6 and 7[4].

A very cold-hardy plant, tolerating temperatures down to about -25°c[8]. The roots are slender and not swollen[8]. The scapes carry between 4 and 12 blooms[1]. Hybridizes freely with other members of this genus[4]. It is closely related to H. vespertina Hara.[9]. Plants take a year or two to become established after being moved[4]. Plants seem to be immune to the predations of rabbits[10].

The plants are very susceptible to slug and snail damage, the young growth in spring is especially at risk[4].
