Allium cernuum - 2026

Allium cernuum is an elegant ornamental onion prized for its nodding umbels of star-shaped flowers that create a charming, delicate effect in summer borders and rock gardens. Blooming from mid to late summer, the clusters of pink to pale pink flowers attract pollinators such as bees and butterflies, adding both movement and biodiversity to the garden. Its slender, arching stems rise gracefully above the basal clumps of strappy green leaves, providing vertical interest without overwhelming surrounding plants. This drought-tolerant, hardy perennial thrives in well-drained soil and is ideal for naturalistic planting schemes, cottage gardens, or containers. Low-maintenance and resilient, it adds seasonal charm with minimal care, and its bulbs can be left undisturbed to naturalise over time.
