Cultivation Details

Allium macropetalum is a plant of semi-arid areas with hot, dry summers and cool, moist winters. It can tolerate winter temperatures dipping occasionally to between -5 and -10°c or lower 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[

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.
