Allium atropurpureum

Plant details

A fun drumstick allium, with a ball of tiny, tightly-packed, maroon-purple flowers on top of a stout stem. The head is not one of the showy big kinds, but is about 5cm (2in) in diameter, and altogether much more refined. In the wild it grows in the Balkans, flowering in June and July, and consequently needs a hot spot with free-draining soil. Grow in clumps, to make elegant combinations.
