Common Name: Black-Violet Leek

General Information

Allium atroviolaceum is a herbaceous perennial plant growing from an underground, globose bulb up to 25mm in diameter. The plant forms a single, flowering stem 60 - 100cm tall with 4 - 5 leaves sheathed around it. The bulb forms numerous bulbils at its base, in time becoming a dense cluster of growth[, ].
The plant is harvested from the wild for local use as a food. It is grown as an ornamental in gardens
Allium atroviolaceum is known to be locally common in parts of its European range, but overall information is lacking in most areas in which it is known to grow. The plant is classified as 'Data Deficient' in the IUCN Red List of Threatened Species(2013)[].

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[].

Agroforestry Uses:

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[].

Other Uses

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[].

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.
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.
