Cultivation Details

Allium giganteum is a plant of semi-arid areas, and can tolerate cold winters with temperatures going below zero - at least down to -5°c without protection in our winter-wet garden in Cornwall, England. However, it grows best when given a dry period in the summer and autumn when it is dormant and so, even in very freely-draining soils, does not usually 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, though it might be sufficient to simply place a cloche over the plant after it has flowered and then remove it when new growth appears in spring[

Medicinal

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[

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 in spring. The plants divide successfully at any time in the growing season, pot up the divisions in a cold frame or greenhouse until they are growing well and then plant them out into their permanent positions.
