Allium 'Globemaster'
When it comes to making a statement, 'Globemaster' is in a class of its own. This magnificent variety boasts some of the largest flower heads available—enormous, 8-10 inch globes packed with thousands of star-shaped, purple florets. What makes 'Globemaster' truly special is its incredibly long bloom time; as new florets open from the center, the flower head continues to expand, maintaining its perfect spherical shape for weeks on end. It’s a living sculpture for your garden, providing a powerful focal point that commands attention and inspires awe. Even after the colour fades, the dried seed heads provide architectural interest well into the winter.
