Common Name:  Swamp onion
Family:  Alliaceae
Author:  Wats.

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:  0.6   Mature Width:

Habitat:  Swampy meadows at medium to high elevations in the mountains[60].

Cultivation Notes: Prefers a sunny position in a light well-drained soil[1]. This species tolerates much wetter soils than most members of the genus but it dislikes winters with alternating periods of damp and cold and no snow cover, so it is best given a damp though well-drained soil[203]. It requires plenty of moisture in the growing season[203]. This species is not hardy in the colder areas of Britain, it tolerates temperatures down to between -5 and -10°c[200]. The bulbs should be planted fairly deeply[1]. 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]. Members of this genus are rarely if ever troubled by browsing deer[233].
