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.
- Garden care: Plant bulbs 10-15cm deep and 10-15cm apart. Avoid excessive mositure from late summer when they become dormant. Over-large clumps can be lifted and divided in autumn or spring.
