The listing, Allium seeds has ended.
This stunning fashionable plant, with large globes of rosy-purple crowded spherical umbels, Allium 'Purple Sensation' is a darker, richer purple than the mauve of its parent. They are popular in both architectural and formal planting plus the long lasting flowers are ideal for cutting.
Held aloft and rising up to 3ft or so before they break, the buds are like a conurbation of Turkish domes. The dense, rich-purple globes appear in early summer held high on erect stems above strap-like, mid green leaves, they never need staking. Extremely easy to grow, the seedlings have a lust for life and only take three years to flower.
Alliums look spectacular grouped in a pot, or in a sunny border, dotted in groups among ornamental grasses, or as part of a Mediterranean scheme. The plants can be allowed to self-seed to make impressive clumps. Plant en masse to be sure to have cut flowers, they flower earlier in full sun an a little later in shade. The flower stalks dry well and can be used in arrangements or they can be left outside to provide winter interest as they look good covered in frost.
The flowers last a long time and help fill that awkward gap between the later spring bulbs and the perennials. By the time the papery tunic on the alliums has broken, the garden is in full swing and caught between spring and summer
