Alium Cowani (White) – Bulbs (set of 5)
Allium Sphaerocephalon, commonly called round-headed leak or drumstick allium, is a bulbous perennial that is ornamentally grown for its early summer bloom of rose-purple to pink flower heads. This plant is native throughout Europe to the Caucasus, Iran, and northern Africa. Cylindrical, hollow, grassy, gray-green leaves to 14″ long-form a foliage clump in spring. In late spring, sturdy slender flowering stems rise to 24-36″ tall topped with egg-shaped flower heads (umbels to 1″ wide) in an impressive early summer bloom (June-July).
Easily grown in rich, sandy to gritty, dry to medium moisture, well-drained loams in full sun. Plants form dense, slowly spreading clumps over time. Plants perform best with consistent moisture during the growing season but tolerate drought after flowering ends. Plant new bulbs 3-5″ (3 times bulb width) deep and 4-6″ apart in fall. Plants may be grown from seed which is usually sown in fall. Plants will self-seed (sometimes prolifically) in the garden, and if left unchecked will naturalize freely.
Ornamental onion for rock gardens, beds, and borders, cottage gardens, open woodland areas and meadows. Best grown in large groups or massed. Maybe naturalized. Grows well in containers. Cut flowers are excellent for both fresh cut and dried flower arrangements.
