Allium 'Purple Rain' Bulb

Allium 'Purple Caila' is a striking ornamental onion renowned for its large, dense, spherical flower heads composed of numerous small, star-shaped florets in a vivid, rich purple colour. Blooming in late spring to early summer, these vibrant blooms sit atop tall, sturdy stems, creating a bold architectural feature in borders, rock gardens, or naturalistic planting schemes. The foliage forms a tidy clump of blue-green, strap-like leaves that provide a subtle backdrop, highlighting the intense flower colour.

The flowers attract pollinators such as bees and butterflies, enhancing biodiversity. Its dramatic colour and form make it a favourite for gardeners seeking a strong and reliable summer floral accent.
