].
The plant is harvested from the wild for local use as a food and medicine. It is used in breeding programmes with the common onion.
Population reduction is suspected to have occurred in this species, and the causes are ongoing due to habitat loss which is cited by Sharma and Gohil (2008) as a particular pressure on this species and well as the issue of sterility limiting population expansion. Furthermore, the local use of the species is reported to be resulting in over-consumption so current and potential levels of exploitation are suspected to be high. The plant is classified as 'Near Threatened' in the IUCN Red List of Threatened Species(2013)[

Cultivation Details


Species in this genus generally prefer a sunny position in a light, well-drained soil.
This species suffers from intrinsic stress in the form of sterility, which is due to meiotic irregularities and chromosomal heteromorphism, which is common in wild populations of this species. This can be counteracted by propagation by bulbs, but this is seriously hindered in nature by a lack of dispersal mechanisms and results in small, restricted subpopulations with little chance of expansion[

Propagation

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.
