Allium 'Purple Sensation' Overview
Allium hollandicum 'Purple Sensation' is one of the most popular Alliums. Its upright, striking, bright-purple round head, is made up of small, densely packed, star-shaped flowers that can grow to 90cm high. This easy to grow bulb needs to be planted in autumn in soil that doesn't get too wet. Allium 'Purple Sensation's' strappy leaves will start dying back before its flower head has fully opened - in early summer - making it ideal for planting in amongst grasses or later growing perennials to give a prairie-style feel. The spent flowerheads will remain for a long time, giving some winter interest or they can be cut for floral arrangements. Allium 'Purple Sensation' is part of the Royal Horticultural Society “Plants for Pollinators” initiative to showcase plants that support pollinator populations by providing ample nectar and/or pollen. A great choice for encouraging pollinating insect wildlife into your garden! It has also earned an RHS Award of Garden Merit.
