Botanical Name: Allium validum
Species: A. validum
Common Names: Swamp onion, Wild onion, Pacific onion, and Pacific mountain onion
Habitat : Allium validum is native to the Cascade Range, to the Sierra Nevada, the Rocky Mountains, and other high-elevation regions in California, Oregon, Washington, Nevada, Idaho and British Columbia. It grows on swampy meadows at medium to high elevations in the mountains.
The Allium validum bulb is three to five centimeters long, ovoid and clustered on the short end. The outer coat of the stout rhizome is brown or gray in color, fibrous, and vertically lined. The stem is 50 to 100 centimeters long and angled. There are three to six leaves more or less equal to the stem and the leaves are flat or more or less keeled. There are 15 to 40 flowers with pedicels being seven to twelve millimeters in length. The flower itself is six to ten millimeters, its perianth parts are more or less erect, narrowly lanceolate, acuminate, and entire with a rose to white color. The stamens are longer than the tepals, and there is no ovary crest.
It is in flower from Jul to August. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees, insects.Suitable for: light (sandy) and medium (loamy) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It prefers moist or wet soil.
Edible Parts: Flowers; Leaves; Root.
Bulb – raw or cooked. The bulb is somewhat fibrous but is very acceptable as a flavouring in soups and stews. The bulb is fairly large, up to 5cm in diameter, and is produced in clusters. The plant has thick iris-like rhizomes. Leaves – raw or cooked. Flowers – raw. Used as a garnish on salads.
Although no specific mention of medicinal uses has been seen for this species, members of this genus are in general very healthy additions to the diet. They contain sulphur compounds (which give them their onion flavour) and when added to the diet on a regular basis they help reduce blood cholesterol levels, act as a tonic to the digestive system and also tonify the circulatory system.
Other Uses: Repellent.……The juice of the plant is used as a moth repellent. The whole plant is said to repel insects and moles.
Prefers a sunny position in a light well-drained soil. This species tolerates much wetter soils than most members of the genus but it dislikes winters with alternating periods of damp and cold and no snow cover, so it is best given a damp though well-drained soil. It requires plenty of moisture in the growing season. This species is not hardy in the colder areas of Britain, it tolerates temperatures down to between -5 and -10°c. 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.
Seed – sow spring in a cold frame. Prick out the seedlings into individual pots when they are large enough to handle – if you want to produce clumps more quickly then put three plants in each pot. Grow them on in the greenhouse for at least their first winter and plant them out into their permanent positions in spring once they are growing vigorously and are large enough. Division in spring. The plants divide successfully at any time in the growing season, pot up the divisions in a cold frame or greenhouse until they are growing well and then plant them out into their permanent positions.
Known Hazards : Although no individual reports regarding this species have been seen, there have been cases of poisoning caused by the consumption, in very large quantities and by some mammals, of certain members of this genus. Dogs seem to be particularly susceptible.
