Known as Golden Garlic or Lily Leek, this species is an exceptionally cheery border perennial. Its golden yellow, starry flowers appear in clusters on 10-15″ stems above handsome, dark green foliage. The late May bloom is a burst of sunshine regardless of the weather. Plant closely together in clumps (5-10 bulbs per sq ft.) among perennials. The leaves of the Allium will go dormant later in summer when the perennials are in their prime.
Cold-hardy to Zone 3.
