Know before you buy
These bulbs should be planted in the fall. This allows them to establish their root systems before the ground freezes, ensuring they are ready to bloom in late spring.
For the best visual impact and healthy growth, space your bulbs 12 to 24 inches apart. This provides enough room for the impressive 10-inch flower heads to develop fully.
Globemaster Alliums are hardy in zones 5 through 8. If you live within these zones, the bulbs will survive the winter in the ground without needing to be lifted.
Yes, Alliums are naturally unappealing to deer, rabbits, and rodents due to their scent and taste. They are an excellent choice if you have issues with garden pests eating your flower beds.
These are low-maintenance plants, but you should allow the foliage to die back naturally after blooming. This ensures the bulb stores enough energy to produce flowers again the following year.
Absolutely. Their sturdy stems and long-lasting, massive violet globes make them excellent for cut flower arrangements.
