Requires a sunny position in a light well-drained soil. The bulbs should be planted fairly deeply. Most members of this genus are intolerant of competition from other growing plants. Grows well with most plants, especially roses, carrots, beet and chamomile, but it inhibits the growth of legumes. This plant is a bad companion for alfalfa, each species negatively affecting the other. Members of this genus are rarely if ever troubled by browsing deer.

Bulb - raw or cooked. An onion substitute. The plants are as pungent as garlic. The bulbs are rather small, about 10 - 20mm in diameter, and are produced in clusters on a short rhizome. Leaves - raw or cooked. The stems and leaves are eaten, they are much favoured in Japan. Flowers - raw or cooked.

Seed - best sown as soon as it is ripe in a greenhouse or cold frame. It germinates quickly and can be grown on in the greenhouse for the first year, planting out the dormant bulbs in the late summer of the following year if they have developed sufficiently, otherwise grow on in pots for a further year. Stored seed can be sown in spring in a greenhouse. Division in summer after the plants have died down. Fairly easy, though we have found that it is best to pot up the divisions until they are growing away strongly before planting them out into their permanent positions.

Rocky and stony places in mountains, usually on calcareous soils.
