Allium nigrum bears pretty cream-white semi-globular white flower heads with a central green eye, over tall, sturdy stems, in late spring to early summer..
It's a fantastic choice for sunny borders, and works well when planted in drifts with ornamental grasses and other alliums. Grow it in sunny herbaceous borders or gravel gardens. It makes a wonderful cut flower.
For best results, plant Allium nigrum bulbs in fertile, well-drained soil up to three times their diameter. Grow in well-drained soil in full sun.
