Allium caesium Bulb

Allium caesium is an elegant ornamental allium species known for its striking spherical umbels of pale blue to steel-blue star-shaped flowers that bloom in late spring to early summer. These delicate yet vivid flower clusters rise above slender green foliage on tall, sturdy stems, creating a refined and eye-catching feature in borders, rock gardens, and mixed perennial plantings. Thriving best in full sun with well-drained soil, Allium caesium prefers sheltered locations to encourage robust growth and a longer flowering period. Once established, it is drought tolerant and requires low maintenance, making it suitable for gardeners seeking a distinctive and graceful floral accent. Native to Central Asia, Allium caesium is not native to the UK but is widely cultivated for its cool blue hues and architectural appeal in temperate gardens.
