Allium hollandicum 'Purple Sensation' AGM
One of the best and most majestic Alliums for the late-spring garden bearing spectacular lilac-purple flowers which are beloved by bees. They have a striking silhouette which makes them particularly well suited to gravel or prairie-style planting schemes used very often in the gardens at the Chelsea flower show. 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). Hence they look great planted with herbaceous geraniums or ornamental grasses, which will help mask these leaves as they die off. Avoid excessive moisture from late summer when dormant so plant the bulbs with some sharp sand underneath to help. Ht to 80cm S 10cm.
