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 wild.

Cultivation Notes: Prefers a sunny sheltered position in a light well-drained fertile soil[1] but tolerates most soils. Tolerates a pH in the range 4.5 to 8.3. The potato onion was at one time fairly widely grown as a vegetable, but it has now fallen into virtual disuse[16]. There are still some named forms available[183]. This is a genuinely perennial form of A. cepa, the bulb grows deeper in the soil and divides to produce a number of underground bulbs each year in much the same way as shallots. Large bulbs divide to form 5 - 15 bulbs whilst smaller bulbs grow into one large bulb[160]. According to one report, the bulbs should be planted fairly deeply[1], whilst another report says that they should be planted just below soil level[4]. Onions grow well with most plants, especially roses, carrots, beet and chamomile, but they inhibit the growth of legumes[18, 20, 54]. This plant is a bad companion for alfalfa, each species negatively affecting the other[201]. Members of this genus are rarely if ever troubled by browsing deer[233].
