Allium nigrum Bulb

Allium nigrum, also known as black garlic, is a stately ornamental onion that produces large, dome-shaped umbels of creamy-white, star-like flowers, each with a distinctive green centre. Blooming in late spring to early summer, its tall, sturdy stems provide strong vertical accents, making it ideal for adding height and structure to mixed borders. This variety thrives in full sun and well-drained soil, where it performs reliably and returns year after year with minimal care. Its soft colouring allows it to blend seamlessly with a wide range of planting schemes, from cottage to contemporary gardens. The long-lasting blooms also make excellent cut flowers and are highly attractive to bees and other pollinators, enhancing the ecological value of the space. Allium nigrum is easy to grow, naturalises slowly, and adds a refined presence to sunny planting areas during the transition from spring to summer.
