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.
Known Hazards
Although no individual reports regarding this species have been seen, there have been cases of poisoning caused by the consumption, in large quantities and by some mammals, of certain members of this genus. Dogs seem to be particularly susceptible.
Distribution
It occurs naturally on low hills in shallow soil that is wet in winter but dry in summer Western North America from Washington to Oregon and Idaho.
Where It Grows
North America, USA,
Cultivation
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.
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.
Notes
There are about 300-700 Allium species. Most species of Allium are edible (Flora of China). All alliums are edible but they may not all be worth eating! They have also been put in the family Alliaceae.
