ALLIUM Purple Sensation

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).
