Drummond's Onion

Allium drummondii

Drummond's Onion is a bulb for bulb layer, edging, suited to full sun to partial shade and clay or loam, flowering Apr, May, Jun.

Where to use it in a border

At around 25 cm, it sits best along the front edge, where a low, spreading habit reads best. Give it about 10 cm of room to spread, roughly 10 to the metre when planted in a drift. It is hardy across USDA zones 5a to 9b and rated H6 by the RHS, so check it suits your area before planting.

It appears in our lists of full sun, clay soil, pollinator-friendly plants.
