Ornamental Leek 'Gladiator' – 10 flower bulbs (size 16/18)

These 10 ornamental onion bulbs, Allium 'Gladiator', will add purple colour to your garden or patio from May through June. Ornamental onions bear round flower heads on tall stems and are a popular source of nectar for bees and butterflies. They look beautiful in borders among perennials, in gravel gardens and in large pots; the spent flower heads remain decorative. The bulb size 16/18 indicates the circumference of the bulbs in centimetres; a larger bulb contains more reserves for flowering.
