Latin Name:  Allium triquetrum
Common Name:  Three-cornered leek
Family:  Alliaceae
Author:  L.

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[76].

Mature Height:  0.35   Mature Width:

Habitat:  Hedge banks and waste places on damp soils[17, 90].

Cultivation Notes: Prefers a rich moist but well-drained soil[1, 42]. Shade tolerant[31], it is easily grown in a cool leafy soil[90] and grows well in light moist woodland[203]. Plants are not very hardy outside the milder areas of Britain, they tolerate temperatures down to between -5 and -10°c. The bulbs should be planted fairly deeply[1]. The seeds have an oil-bearing appendage which is attractive to ants. The ants carry the seed away to eat the oil and then discard the seed, thus aiding dispersal of the plant[203]. Grows well with most plants, especially roses, carrots, beet and chamomile, but it inhibits the growth of legumes[18, 20, 54]. This plant is a bad companion for alfalfa, each species negatively affecting the other[201]. The flowers are sweetly scented[245]. The picked flowers can remain fresh for several weeks[89]. Members of this genus are rarely if ever troubled by browsing deer[233].
