  • 'Purple Sensation' is probably one of the most popular of all the alliums. They have a striking silhouette which makes them particularly well suited to gravel or prairie-style planting schemes, but they also look fab in pots or mixed borders. Their densely packed umbels of deep violet, star-shaped flowers appear in early summer above strap-shaped grey-green leaves (which will have already started to die off by the time the blooms form). Therefore, they team up well then with things like herbaceous geraniums or ornamental grasses, which will help mask these leaves as they die off.

  • Garden care: Bulbs can be planted 15cm deep and 15cm apart. Pot-grown plants can be enjoyed as they are while in bloom, but as the flowers fade, they should either be potted up or planted out in the garden. Avoid excessive mositure when the plants become dormant (from late summer) and lift and divide over-large clumps in autumn or spring.
  • Pets: TOXIC if eaten; Humans: Ornamental bulbs - not to be eaten
