Allium neapolitanum Cowanii Group (ornamental onion bulbs)

Position: full sun Soil: fertile, well-drained soil Rate of growth: average to fast Flowering period: April to May Hardiness: fully hardy Bulb size: 4/5 Open clusters of pure white flowers appear in late spring or early summer, creating a soft, lacy effect. The flowers of this allium last for ages after being cut and the bees will find them very attractive, so try to plant them in large numbers. In smaller gardens, they look great in pots where they can sit on a sunny patio.
