Ornamental Onion 'Purple Sensation' – 120 flower bulbs (bulb size 10/12)

These 120 ornamental onion bulbs, Allium 'Purple Sensation', 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. Bulb size 10/12 indicates the circumference of the bulbs in centimetres; a larger bulb contains more energy reserves for flowering.
