Synonyms: A. anceps. Kellog.
Habitat :Allium platycaule is native to northeastern California, south-central Oregon (Lake County) and northwestern Nevada (Washoe and Humboldt Counties). Itgrows on slopes of elevations of 1500–2500 m.
Allium platycaule grows from a gray bulb two to three centimeters wide. Scape is thin and strongly flattened, up to 25 cm long but rarely more than 7 mm across. It may be thicker along the midrib and much narrower along the sides. The long, flat leaves are sickle-shaped.
It is in flower from May to June. Atop the stem is an umbel which may have as many as 90 flowers in it. Each flower may be up to a centimeter and a half wide but the tepals are quite narrow so as to be almost threadlike. The inflorescence therefore may appear be a dense ball of filaments. The flowers are generally bright pink to magenta with yellow anthers.
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 dry or moist soil.
Prefers 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.
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.
Bulb – eaten raw or cooked. The bulbs are formed in clusters on a rhizome and are about 20 – 35mm in diameter. Leaves – raw or cooked. Used as an onion-flavoured relish. Flowers – raw. Used as a garnish on salads. The seed heads can be placed in hot ashes for a few minutes, then the seeds extracted and eaten.
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.
The juice of the plant is used as a moth repellent. The whole plant is said to repel insects and moles
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[
