Allium sphaerocephalon Bulb

Allium sphaerocephalon, commonly known as drumstick allium, is a distinctive and eye-catching ornamental onion valued for its dense, oval-shaped flower heads composed of numerous tiny, deep purple to burgundy florets. Blooming in early to mid-summer, these striking flower clusters are held on slender, upright stems above narrow, grass-like leaves. This species thrives in full sun to partial shade and prefers well-drained soil, making it ideal for borders, rock gardens, and naturalistic plantings. Allium sphaerocephalon is drought-tolerant and low-maintenance, providing bold colour and architectural interest to a variety of garden styles. Its flowers attract pollinators such as bees and butterflies, supporting garden biodiversity. The unique shape and vibrant colour of the blooms add dynamic texture and contrast, making it a popular choice for gardeners seeking a dramatic and resilient summer-flowering allium.
