Although no specific mention of medicinal uses has been seen for this species, members of this genus are in general very healthy additions to the diet. They contain sulphur compounds (which give them their onion flavour) and when added to the diet on a regular basis they help reduce blood cholesterol levels, act as a tonic to the digestive system and also tonify the circulatory system[K].

Other Uses

Cultivation details

Landscape Uses:Border. A very easily grown plant, it prefers a sunny position in a light well-drained soil[1, 203]. It succeeds in clay soils and also in areas of higher rainfall, so long as the soil drains fairly well[203]. A very variable species with forms ranging in height from 8 - 50cm[203]. Closely related to A. carinatum[203]. The bulbs should be planted fairly deeply[1]. Most members of this genus are intolerant of competition from other growing plants[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]. Members of this genus are rarely if ever troubled by browsing deer[233]. Special Features: Not North American native, Naturalizing, Suitable for cut flowers, Suitable for dried flowers.

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 bulbs in late summer or the autumn. Larger bulbs can be planted straight out into their permanent positions, though it might be best to pot up the smaller bulbs and grow them on for a year before planting them out..
