Allium Purple Sensation – Bulbs

Allium Purple Sensation is one of the most striking ornamental onions, producing tall stems topped with dense, spherical heads of vivid violet florets. Flowering in late spring to early summer, it brings bold structure and long-lasting colour to borders and mixed planting schemes.

The dramatic, globe-shaped flowers are highly attractive to pollinators and remain ornamental even as seed heads, providing extended interest. Excellent as cut flowers or dried for arrangements, they are versatile both in the garden and indoors.
