Allium backhousianum 'Green Craze'

A deciduous, bulbous perennial, producing strap-shaped mid-green leaves and densely packed, spherical heads of white flowers on straight stems to 1m (39in) tall, in July and August. The flowers are extremely attractive to bees and other pollinating insects, making the plant a wonderful addition to a wildlife garden. The flowers are followed by large ornamental seed-heads initially green but eventually turning brown. They can be used either for cutting or to provide interest in the winter garden.
