Allium Firmament

(inc. 20.0% VAT)



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.
