Known Hazards:  There have been cases of poisoning caused by the consumption, in large quantities and by some mammals, of this plant. Dogs seem to be particularly susceptible[76].

Mature Height:  1.2   Mature Width:

Habitat:  Not known in the wild.

Cultivation Notes: Prefers a sunny position in a light well-drained soil[1] but succeeds in most soils that are in good condition[16]. Tolerates a pH in the range 4.5 to 8.3. The bulbs should be planted fairly deeply[1]. The tree onion is a genuinely perennial form of A. cepa that is sometimes grown in the herb garden for its edible bulbils. Plants rarely if ever produce seed, instead the flowering head is comprised of a number of small onions or bulbils[16, 33]. Plants are propagated by means of these bulbils or by dividing the main bulb that grows underground[K]. By no means a heavily productive plant, though the bulbils are very well flavoured and the plant is fairly easily grown[K]. Its main problem is that slugs seem to be attracted to it and can eat to death even well-established plants[K]. 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]. Said to be immune to onion root fly[16]. Members of this genus are rarely if ever troubled by browsing deer[233].
