Allium nigrum is a distinctive and ornamental flowering onion with unique features.
Characterized by its striking spherical flower heads, this Allium species boasts tightly packed clusters of star-shaped flowers that range in color from creamy white to light green. The individual florets form a dense umbel, and the entire flower head can measure up to 3 inches in diameter. The slender, arching stems rise gracefully above the basal foliage, which consists of long, linear leaves. Blooming in late spring to early summer, Allium nigrum adds both elegance and contrast to the garden. This perennial bulb is not only visually appealing but also attracts pollinators, making it a valuable addition to the landscape.
