Why We Love It

Allium ‘Purple Sensation’ is one of the most dramatic and reliable ornamental onions, much loved for its tall stature and vibrant spherical blooms. Each flower head, up to 10cm across, creates a striking architectural presence in the garden and makes an excellent cut flower for arrangements.

Ideal for planting in groups or weaving through perennial borders, these alliums bring height and rhythm to planting schemes, complementing early summer perennials and roses. Their upright habit also makes them perfect companions for ornamental grasses, creating a modern, textural look.

As well as being stunning, they are also resilient and easy to grow, a low-maintenance choice for long-lasting impact.
