Allium acuminatum
Allium acuminatum
Family: Amaryllidaceae
Cultivation
Although capable of tolerating winter temperatures considerable below zero, this species grows in semi-arid areas with a distinct dry season in the summer and autumn, and the bulbs tend to rot when grown in cool wet climates, even if they are given sharp drainage. When growing it in moister environments, the plant needs some protection from the wet - this can sometimes be achieved by simply placing a cloche over the plant after flowering, or by growing it in a frame. Prefers a sunny position in a light well-drained soil.

Allium roylei
Family: Amaryllidaceae
Cultivation
Allium roylei Species in this genus generally prefer a sunny position in a light, well-drained soil. This species suffers from intrinsic stress in the form of sterility, which is due to meiotic irregularities and chromosomal heteromorphism, which is common in wild populations of this species. This can be counteracted by propagation by bulbs, but this is seriously hindered in nature by a lack of dispersal mechanisms and results in small, restricted subpopulations with little chance of expansion.

Allium rubellum
Family: Amaryllidaceae
Cultivation
Allium rubellum is a plant of semi-arid areas in central and eastern Asia, and can tolerate cold winters with temperatures going below zero. However, it requires a dry period in the summer and autumn when it is dormant and so, even in very freely-draining soils, does not do very well outdoors in areas with summer and autumn rain. In such areas it is best grown in a cold greenhouse or bulb frame.

Allium ruhmerianum
Family: Amaryllidaceae
Cultivation
Allium ruhmerianum is native to the Mediterranean region, with its hot, dry summers and cool, moist winters. It can tolerate winter temperatures dipping occasionally to between -5 and -10°c but, even in well-drained soils, can be killed by summer wet. In moister parts of the temperate zone it is probably best to grow the plant in a bulb frame, with water being withheld in late summer.

Allium sativum
Allium sativum
Family: Amaryllidaceae
Cultivation
Garlic was originally a plant of warm temperate areas with a distinct cold season and a change of daylength from short days in the winter to long days in the summer. In Spring, when days are cooler and shorter, the plant focuses mainly on leaf growth, but with lengthening, hotter days the focus moves to bulb production. The plant can be grown in tropical areas, but only really succeeds at elevations above 500 metres, and preferably below 2,00 metres.

The plant is thriving at the Botanic Gardens, Kew, England (zone 7); and so is hardier than the books say. Easily grown in a warm sunny position.

Allium tuberosum
Family: Amaryllidaceae
Cultivation
Garlic chives succeeds in temperate and tropical climates. High temperatures encourage bulb formation, but flower formation and seed production are only possible where the bulbs are subjected to low temperatures. In the tropics, flower and seed formation can therefore only occur at higher elevations, but generally the plants seldom produce seeds in the tropics.

Although capable of tolerating winter temperatures considerable below zero, Allium unifolium grows in areas with a distinct dry season in the summer and autumn, and the bulbs tend to rot when grown in cool wet climates, even if they are given sharp drainage. When growing it in moister environments, the plant needs some protection from the wet - this can sometimes be achieved by simply placing a cloche over the plant after flowering, or by growing it in a frame. Prefers a hot dry sunny position in a light, rich well-drained soil.
