Allium Purple Sensation is a striking ornamental onion that adds bold colour and structure to the late spring and early summer garden. Its large, rounded flower heads are packed with vivid purple florets, creating a dramatic display that looks stunning planted in groups through borders or dotted among perennials. An RHS Award of Garden Merit winner, this variety is loved not only for its beauty but also for its reliability and ease of growth.

Flowering in May and June, Allium Purple Sensation is highly attractive to pollinators, providing valuable nectar for bees and butterflies. Standing tall at around 90cm, it is ideal for the middle or back of borders, where its vibrant blooms add height and texture. The flowers also make excellent, long-lasting cut blooms and retain their beauty when dried for arrangements.
