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


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. The tubular flowers are about 7.5cm long and 13cm in diameter[1]. Each stem carries 6 - 8 flowers[1]. The flowers contain carotene and starch[2][3]. The flower buds contain about 43mg vitamin C per 100g, 983 IU vitamin A and 3.1% protein[1].

Root - raw or cooked. A radish-like flavour but not so sharp[1].



Material uses

The tough dried foliage is plaited into cord and used for making footwear[1].

Unknown part

Medicinal uses(Warning!)

The juice of the roots is an effective antidote in cases of arsenic poisoning[1]. A tea made from the boiled roots is used as a diuretic[1].

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]. Seed is only set if the plant is fertilized by another species, thus seedlings will not be true to the species type[4]. 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[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.

Succeeds in most soils[6], including dry ones, preferring a rich moist soil[1]. 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[1]. Succeeds in short grass if the soil is moist[6]. Prefers a pH between 6 and 7[5].

Hybridizes freely with other members of this genus[5]. The roots have spindle-shaped swellings[1]. The cultivar 'Major' is smaller than the type species, but has larger flowers, it is sometimes cultivated for these edible flowers in Japan[1]. There is some doubt as to whether this cultivar really is a form of H. aurantiaca[1]. Individual flowers are very short-lived, opening in the morning and withering in the evening[1]. Plants take a year or two to become established after being moved[6]. Plants seem to be immune to the predations of rabbits[4]. The plants are very susceptible to slug and snail damage, the young growth in spring is especially at risk[5].

There is some doubt as to the origins of this plant, it might have arisen in cultivation at Kew[1]. It is cultivated in Japan, where it is believed to have come from China[7]. It is quite possibly a hybrid since it is sterile unless fertilized by another species[4].
