Allium 'Purple Sensation': The Iconic Spring Statement

Transform your late-spring garden with the world's most popular ornamental onion, Allium 'Purple Sensation'. Renowned for its intense, deep violet colour, this award-winning variety is the gold standard for bridging the gap between spring bulbs and summer perennials. Each sturdy stem is topped with a perfectly spherical flower head measuring up to 10cm across, composed of dozens of star-shaped florets. It is a reliable perennial that returns year after year, providing striking vertical accents that seem to float above the garden bed. Whether planted in tight clumps or drifted through a border, it delivers unbeatable architectural drama at an affordable price.

  • Vivid Colour: Famous for its rich, electric-purple hue that stands out sharply against the fresh greens of May foliage.
  • Award-Winning Performance: A recipient of the prestigious RHS Award of Garden Merit, guaranteeing it is a robust, reliable, and excellent plant for the garden.
  • Pollinator Superfood: The globe-shaped blooms are covered in nectar-rich florets that are irresistible to bees, hoverflies, and butterflies.
  • Structural Seed Heads: Once the colour fades, the seed heads turn into straw-coloured spheres that persist for weeks, adding structure to the summer garden or interest to dried flower arrangements.

Gardener's Tip: Hiding the Leaves

Like many large-flowered alliums, the foliage of Purple Sensation begins to die back and turn yellow just as the flowers reach their peak. To keep your display looking pristine, plant these bulbs behind low-growing perennials such as Hardy Geraniums, Alchemilla Mollis (Lady’s Mantle), or Hostas. These companions will hide the fading leaves while allowing the magnificent purple globes to rise elegantly above them.
