Collection: Allium Bulbs

Allium bulbs, the ornamental onions, for big globe flowers in late spring. Choose from giant purple 'Globemaster', tall 'Gladiator' and 'Purple Sensation', round 'Dallas' and 'Pinball Wizard', the starburst heads of 'Schubertii' and the white Allium nigrum.

Plant them from September to November in full sun, about two to three times as deep as the bulb is tall, in a border or a large pot. They are fully hardy and can stay in the ground all year, but the bulbs rot if the soil stays wet through winter, so choose a well-drained spot.

Alliums are popular with bees and other pollinators, and they make good cut flowers. The tall varieties look best rising through lower perennials.

Each bag is listed with the number of dry bulbs inside, and the photos show the flowers in bloom. See also our tulip bulbs, daffodil bulbs and all spring-flowering bulbs.
