Medicinal uses(Warning!)

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].

Propagation

Seed - sow spring in a greenhouse. The seed can also be sown as soon as it is ripe 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 plants in summer as they die down. The divisions can be planted direct into their permanent positions if required.

Cultivation

Prefers a sunny position in a light well-drained soil[9].

Plants are not hardy in the colder wetter conditions of N.W. Britain and are probably best grown in a bulb frame in most parts of the country[10]. The sub-species A. geyeri tenerum forms bulbils in its flowering head[10]. The bulbs should be planted fairly deeply[9]. Most members of this genus are intolerant of competition from other growing plants[10]. Grows well with most plants, especially roses, carrots, beet and chamomile, but it inhibits the growth of legumes[11][8][12]. This plant is a bad companion for alfalfa, each species negatively affecting the other[13].

Members of this genus are rarely if ever troubled by browsing deer[14].
