Open clusters of pure white flowers appear in late spring or early summer, creating a soft, lacy effect. The flowers of this Allium neapolitanum Cowanii Group 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.
How to care for Allium neapolitanum Cowanii Group:
Allium bulbs are easy to grow in a sunny spot with freely drained soil, or a good quality potting compost. Ideally they should be planted in September or October, but could also be planted in early November in milder regions. Dig holes roughly three times as deep as the diameter of the bulb and place them at the base, pointy side up before gently infilling and watering to settle them in. In early spring, as growth begins, apply a balanced, slow-release fertiliser, and allow the plants to die back naturally and completely before tidying away.
