- Command instant attention with the jaw-dropping, perfectly spherical, intense deep-violet flower heads of this spectacular, multi-award-winning ornamental onion.
- Allium 'Purple Sensation' is the absolute ultimate architectural plant, providing phenomenal, striking vertical accents that look breathtaking when woven through grasses.
- This allium bridges the gap perfectly between spring bulbs and summer perennials, creating a massive, high-impact explosion of color in the early summer border.
- It is an absolute magnet for bees and butterflies, while its subtle onion scent ensures it is completely ignored by deer, rabbits, and other garden pests.
- The stunning, globe-like seed heads persist for months, providing incredible, highly structural interest long after the vivid purple color has faded.
