Allium x 'Globemaster'
Guaranteed to arrive healthy. details →
Globemaster produces violet-purple spheres up to 10 inches across on stems near three feet, and they hold that shape for weeks. Allium 'Globemaster' grows 32 to 34 inches tall and 12 to 18 inches wide in full sun to part sun, hardy from Zone 5 through Zone 8.
Bloom comes in late spring, and each sphere is made of hundreds of small star-shaped flowers that bees visit steadily. The dried heads stand well into summer and hold their form, so leave them up.
The strap-shaped basal leaves yellow and die back as the flowers open, which is normal. Plant something leafy in front to cover them.
Alliums want full sun and sharp drainage, and they rot in ground that stays wet, particularly over winter. They handle drought once established, and the onion scent in the foliage is what keeps deer, rabbits, and voles away from them.
