Description
With its reddish-purple and bluish-purple to deep pink umbels that stretch two inches across, this exotic Eastern European brings up immediate visions of night falling upon a wild landscape. Bees and butterflies love the taste of Allium atropurpureum, while animals don’t, so it’s an excellent addition to any garden, either in pots or the ground. It adores sunlight and prefers well-drained soil. To create the best effect, make sure to plant the tall and moody Allium atropurpureum in clusters. Their colours also fit in marvellously with perennials such as roses. You’d never think this prize winner was a humble onion, but it is!
