The color of the Blue Allium is reminiscent of a clear blue summer sky and is also fittingly called Blue-of-the-Heavens. Dense, 1-2” round bundles of tiny blue flowers set atop sturdy stems and are stunning when planted in groups, mixing in well with other spring flowering bulbs and early blooming plants, such as poppies and forgot-me -nots.
