Helping You Become a More Successful Gardener

ALLIUM senescens ssp. glaucum
Blue Siberian Onion
Named for its spiraling blue-gray leaves, this North Asian native is also noted for its small dense umbels of cup-shaped lilac-pink flowers, which bloom from mid to late summer. The finger-length, flattened, strap-shaped leaves appear in spring and remain attractive all season. They emit an onion scent when crushed. The leaves and flower stems grow from narrow bulbs clustered on a shallow rhizome.
Blue Siberian onion prefers sun and well-drained soil and tolerates drought once established. Lift and divide the clumps only when they become crowded. Grow this diminutive plant in groups in the mixed border, alpine bed, rock garden, or containers. Deadhead to prevent self-sowing.
