Allium sphaerocephalon Flower Bulbs Flowering later than most with many dark coloured 'bullet' shaped blooms appearing in July and August. In addition, very easy to grow and long lasting.

A genus of great diversity grown for their highly decorative and ornamental flowerheads. They make excellent cut blooms and the larger flowered types are well suited to drying.
