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[4][5]. Blanching the leaves removes this hallucinatory component[9]. (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[2][3]. They must be consumed when very young or else they become fibrous[K]. Flowers and flower buds - raw or cooked[2][6]. They 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[9]. Root - raw or cooked[9]. A pleasant nutty flavour.

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[8]. 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[8] but tolerating partial shade. Plants flower less freely in a shady position though the flowers can last longer in such a position[9]. Grows well in heavy clay soils. Succeeds in short grass if the soil is moist[1]. Prefers a pH between 6 and 7[8]. Hybridizes freely with other members of this genus[8]. Unlike the type species, this form does produce viable seed[7]. Plants take a year or two to become established after being moved[8]. Individual flowers are short-lived, opening in the morning and withering in the evening. The plant, however, produces a succession of flowers over a period of about 6 weeks[9]. 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[8].
