This taxon is not universally accepted as a distinct species. It is treated as a synonym of Allium spirale Willd., in the Flora of China[
It is closely related to the domesticated species Allium nutans[
Allium austrosibiricum is a herbaceous perennial plant growing from an underground bulb; it produces a cluster of 4 - 6 grass-like leaves and a flowering scape that is 15 - 40cm tall. The bulbs are produced on a shortly-creeping rhizome, developing in time into a dense cluster of bulbs[
The plant is harvested from the wild for local use as a food.
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[
Asia - southern Siberia, northwestern Mongolia
Species in this genus generally prefer a sunny position in a light well-drained soil[
The plant is used as a vegetable and source of vitamins[
]. No more information is given, but Alliums in general have more or less edible bulbs, flowers and leaves[
Allium species usually grow well with most plants, especially roses, carrots, beet and chamomile, but they inhibit the growth of legumes[
]. They are, in general, bad companions for alfalfa - each species negatively affecting the other[
Members of this genus are rarely if ever troubled by browsing deer[
Although no specific mention has been seen for this species, the juice of most species in this genus (especially those with a strong onion or garlic smell) can be used as a moth repellent[
The whole plant is said to repel insects and moles[
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 of the clump. Individual bulbs or larger clumps can be separated from the main clump - individual bulbs can be planted directly into their permanent position, but are probably best grown in pots or a nursery bed until established. Larger divisions can be planted direct into their permanent position.
