Plant details

A superb, low-maintenance perennial, flax is short-lived but self-seeds and slowly naturalises itself around the garden among other plants, but never enough to become a nuisance. The short, wiry stems support huge quantities of wide-open 2.5cm (1in) flowers, as intensely blue as a summer sky. Each lasts for a day, but there are always lots more buds opening. Leave self-sown seedlings that appear in suitable situations. If left undisturbed, these are much more drought-tolerant and self-sufficient than transplants. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).
