How to Identify

An onion family bulb plant. It grows to 30 cm high and spreads to 12 cm across.

How to Grow

Prefers a sunny position in a light well-drained dry to moist soil. The bulbs should be planted fairly deeply. 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.

Propagation: Sow seed in spring in a cold frame. Prick out seedlings into individual pots once large enough to handle, or place three per pot to produce clumps more quickly. Grow on in the greenhouse through at least the first winter before planting out in spring once vigorous and large enough. Division is best done in spring, though plants can be divided successfully at any point during the growing season. Pot up divisions in a cold frame or greenhouse until well established, then plant out into permanent positions.

Medicinal Uses

No specific medicinal uses have been recorded for this species, but like other members of its genus it makes a healthy addition to the diet. It contains sulphur compounds that give it its onion flavour, and eaten regularly it can help reduce blood cholesterol levels, support digestive health, and tonify the circulatory system.

Other Uses

The juice of the plant can be used as a moth repellent. The whole plant is also said to repel insects and moles.
