Bloomsz Allium Gladiator Flower Bulb (2-Pack) Blooms lasting 3-4 weeks Can be grown successfully in containers and tubs. Use to add interest to cut flower arrangements. Deer resistant. Hardy in Zones 4-10 Grow in full sun to light shade in where the soil drains well. Planting tip: Select a site carefully for your Allium Gladiators. Because they do not like to be moved, permit them to stay where they were originally planted for 3-4 years before moving them to another location. Bulblets often form along the main bulb. When flowers diminish in size, dig the bulbs up in the fall, remove the bulblets and plant them in another location or give them to family members and friends to use in their gardens.
