Cultivation Details

HabitBulb
Growth—

Allium obliquum is an easily grown plant succeeding in areas with cold winters and also tolerant of heavy rainfall areas[2]. An easily grown plant[2], it prefers a sunny position in a light well-drained soil[3]. Succeeds in damp acid soils and in heavy clay[2]. The bulbs should be planted fairly deeply[3]. This species is closely related to the Welsh onion, Allium fistulosum[2].

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. Very easy, the plants divide successfully at any time in the growing season and the divisions can be planted straight out into their permanent positions if required.
