A perennial growing to 0.3m by 0.3m The basal fern like leaves are pinnately compound with deeply toothed leaflets that get progressively larger toward the tip end. The flowering stem remains leafless, with the exception of two small dissected leaves near midlength. The flowers normally come in threes. The reddish sepals fuse at the based to form a bowl shaped structure from which the five petals and numerous stamen arise. The yellow to red petals are nearly hidden by the sepals. Long, soft hairs sparely to densely cover the entire plants. As the fruits mature the style become very long and feathery, presenting the appearance of a beard or whiskers. It is in flower from July to August. It grows in large patches in the wild and prefers light (sandy), medium (loamy) and heavy (clay) soils and requires well-drained. moist soil. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade.
Easily grown in any moderately good garden soil that is well-drained. Prefers a rather damp soil rich in organic matter. Plants are hardy to about -20°c.
Division in spring or autumn. This should be done every 3 - 4 years in order to maintain the vigor of the plant. Transplanting is very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.
