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. Cylindrical, hollow, grassy, gray-green leaves to 14″ long form a foliage clump in spring. An impressive early summer bloom. Each flower head is a tight, dense, clover-like cluster of tiny florets that emerge deep green but mature to rose-purple. Each flower head displays an interesting bi-color effect as the florets change from green to purple. This species blooms later than most of the alliums.
