Allium Firmament
M5005
Description
Dark amethyst stars are produced in dense clusters, forming eye-catching spheres of purple on Allium ‘Firmament’.
A cross between Allium Atropurpureum and Christophii, this striking cultivar boasts the best qualities of both varieties, with tall, strong stems and densely packed, richly coloured flowers.
A brilliant choice for sunny summer borders and for cutting and arranging. ‘Firmament’ looks fabulous in a prairie planting scheme, studding hazy drifts of perennial grasses with pops of purple.
Plant the bulbs in clusters or ribbons for a natural look and for the best impact. Well-drained soil and full sun are essential for this excellent Allium to thrive.
Care Guide
Plant in rich, well-drained soil.
The larger bulbs should be planted 10cm (4”) deep and the smaller ones 5cm (2”) deep; they may be left undisturbed for many years.
