RHS Plants for Pollinators

Allium 'Serendipity' PP32023 CPBRAF

This ornamental onion has attractive blue foliage, above which are produced masses of rosy-purple flowers, much adored by bees and other pollinators. Hardy and easy to grow. Brilliant for patio containers or rock gardens. This plant dies down in winter to regrow in spring.

Plant Care

Keep well watered until firmly established. Plant into any average garden soil, avoiding wet areas.

Planting Instructions

Water thoroughly, or stand pot in a container of water for half an hour before planting. Dig a hole twice the size of the root ball. Remove the pot, place the plant in the hole so that the root ball is level with the surrounding ground and refill, firming if necessary. Keep well watered in dry weather. Feed in spring with a good, general fertiliser.
