We fell in love with this allium as soon as we saw it. In early to midsummer each upright stem is crowned with a rounded cluster of small flowers, each with a ruff of rounded white petals that surround a prominent blueberry-purple centre. They are great for adding structural interest to the border, and their flowers are ideal for cutting.
Garden care: Plant bulbs 15cm deep and 15cm apart to enjoy the full effect of the flowers. Avoid excessive moisture from late summer when they become dormant. Over-large clumps can be lifted and divided in autumn or spring.
