Allium Christophii (or Cristophii, or Allium albopilosum) is known as the Star of Persia for good reason. A compact variety of ornamental onion, with star-shaped flowers held in a globe cluster of 20cm diameter in early summer. The soft lilac flowers look like sparklers, and appear to have a metallic sheen to them. Curled, strappy mid-green leaves will have already begun to wither before then, so plant amid other perennials to conceal the leaves.
Attractive to butterflies and bees, this hardy perennial bulb has a long flowering season. Plant in the middle of the border, so the umbrels can grow through other foliage such as paeonies; it can take over from tulips. Also ideally suited to gravel gardens or prairie style planting.
The flowers and the attractive seed-heads are both the first choice allium for flower arranging, making this a good all-rounder for your garden.
A recipient of the RHS AGM (Award of Garden Merit), for all round excellence in the garden.
