Description

Allium ‘Purple Rain’ is a dazzling ornamental onion that combines architectural height with dramatic colour. Its globe-shaped umbels burst into hundreds of starry violet-purple florets in late spring to early summer. A reliable cross between Allium ‘Purple Sensation’ and Allium cristophii, it delivers the best of both: strong upright stems and spectacular display. Perfect for mixed borders, prairie-style planting, or as a focal point among perennials and grasses. Drought-tolerant and adored by bees and butterflies, this allium also makes an excellent long-lasting cut flower. Plant in full sun with well-drained soil and watch the fireworks begin.
