Nothing creates instant impact quite like the bold flower heads of Allium hollandicum. Strong upright stems are topped with large, perfectly rounded globes packed with hundreds of vivid violet-purple star-shaped flowers, creating a spectacular display in late spring and early summer. The impressive blooms rise above surrounding planting, adding height, structure and architectural elegance to borders while attracting bees and other beneficial pollinators. Their distinctive spherical shape pairs beautifully with softer perennials and ornamental grasses, and the attractive seed heads continue to provide interest long after flowering has finished. Whether planted in generous drifts or dotted through mixed borders, this outstanding ornamental onion brings lasting drama and effortless sophistication. RHS Recommended: Award of Garden Merit. Height: 80cm to 1m (31in to 3.2ft). Spread: 20cm (8in).
