Allium triquetrum

Allium (Species) Three Cornered Leek

A complete thug which will take over your garden. Sun or shade, it just doesn't care. A cousin to wild garlic. Rather lovely in late spring. It will disappear in mid-summer and return with new leaves and ferocity next spring. Best of luck trying to get rid of it where you don't want it. Every tiny bulb will grow anew.

Planting

From Late Autumn TO Early Spring

Garlic is planted from bulb segments (cloves), so break up the bulb carefully into individual cloves prior to planting, and then plant the cloves pointed end up with the tips 1" (2.5 cms) below the soil surface, in fertile, dry soil, in a sunny site. Plant 6" (15 cmc) apart, with 1' (30 cms) between rows. Allow 15cm (6in) between individual cloves and 30cm (1ft) between rows. Plant the cloves so the tips are 2.5cm (1in) below soil surface. Deeper planting can encourage better yields on light soils, but do not plant deeply on heavy soils. After planting, garlic needs a cool, one- to two-month period at temperatures of 0-10°C (32-50°F) for good bulb development. Planting in late autumn or in early spring (depending on the cultivar) will provide the necessary chilling period.
