Prefers a well-drained light, rich or peaty soil. Prefers a sandy soil and a sunny position. Prefers a slightly acid soil. Prefers a dry soil. Plants are hardy to about -20°c. Another report says that this species is only suited to the warmer areas of Britain. A very ornamental plant, but it is not easy to establish or to keep in British gardens. Resents root disturbance, plants should be pot-grown from seed and planted out in their permanent positions when young. Plants are particularly at risk from slugs, however, and some protection will probably be required until the plants are established and also in the spring when the new shoots come into growth. The flower can trap insects between its anther cells, the struggles of the insect in escaping ensure the pollination of the plant.

Whilst most parts of this plant have been used as food, some caution is advised since large doses can cause diarrhoea and vomiting - see the notes above on toxicity. Flower buds - cooked. They taste somewhat like peas. Young shoots - cooked. An asparagus substitute. The tips of older shoots are cooked like spinach. Young seed pods - cooked. Harvested when 3 - 4 cm long and before the seed floss begins to form, they are very appetizing. The flower clusters can be boiled down to make a sugary syrup. In hot weather the flowers produce so much nectar that it crystallises out into small lumps which can be eaten like sweets, they are delicious. Root - cooked. A nutty flavor. Some reports say that it is poisonous. An edible oil is obtained from the seed. The seed is very small, however, and commercial usage would not be very viable.

Seed - best sown in a greenhouse as soon as it is ripe in the autumn or in late winter. We have also had good results from sowing the seed in the greenhouse in early spring, though stored seed might need 2 - 3 weeks cold stratification. Germination usually takes place in 1 - 3 months at 18°c. As soon as the seedlings are large enough to handle, prick them out into individual pots and grow them on in the greenhouse for their first winter. Plant out when they are in active growth in late spring or early summer and give them some protection from slugs until they are growing away strongly. Division in spring. With great care since the plant resents root disturbance. Pot the divisions up and place them in a lightly shaded position in the greenhouse until they are growing away strongly, then plant them out in the summer, giving them some protection from slugs until they are established.. Basal cuttings in late spring. Use shoots about 10cm long with as much of their white underground stem as possible. Pot them up individually and place them in a lightly shaded position in a greenhouse until they are rooting and growing actively. If the plants grow sufficiently, they can be put into their permanent positions in the summer, otherwise keep them in the greenhouse until the following spring and when they are in active growth plant them out into their permanent positions. Give them some protection from slugs until they are established.

Dry open sandy and gravelly soils and grassy places by the sides of roads.
