Allium 'Globemaster' is a spectacular hybrid ornamental onion that produces the largest flower heads of any allium — massive, dense, spherical globes up to 10 inches across, composed of hundreds of star-shaped, violet-purple flowers. Blooming in late spring on tall, sturdy stems, the heads dry beautifully. A showstopper for perennial borders and a magnet for pollinators.
