Description

Compact, striking, and loved by pollinators, Allium ‘Ostara’ is a standout spring bloomer that brings sculptural form and rich colour to borders and containers. Its deep purple, globe-shaped flowers sit proudly atop sturdy stems above neat, strappy foliage—ideal for small spaces or layered planting schemes.
