The flowers on this allium are quite papery, which means they last longer than many of the other varieties. In spring the first sign of growth is the appearance of the strappy foliage. This has usually died off by the time the flowers appear in late spring. The pinky-purple, bell shaped flowers emerge in clusters of up to 20 at a time on top of single stems. A great plant for an alpine bed or to add colour to the front of a mixed border. - Garden care: Plant bulbs 5cm deep and 5cm apart in clumps or drifts. Avoid excessive soil moisture and split and divide large clumps in autumn or spring.
