Allium 'Summer Drummer'

Allium 'Summer Drummer' is one of the tallest and most striking ornamental onions, delivering a spectacular highlight in the garden late in the season. Blooming from June to August, it produces large, dense, globe-shaped flower heads in deep purple, each tiny flower tipped with white—creating a lively, almost dotted pattern across the sphere.

The stems can reach up to 180 cm, standing tall and majestic above narrow, blue-green foliage that dies back as flowering begins. 'Summer Drummer' is perfect for adding height, rhythm, and late-season structure to perennial borders or more architectural garden designs, where its dramatic silhouette draws both attention and pollinators. A drummer of the late bloom—rhythmic, bold, and unforgettable.
