Propagation
Seeds may be sown untreated if kept moist.  Dry seeds need to be stratified for 30 days at 7.2ºC (45ºF) prior to sowing during spring.

Division of suckers from horizontal roots during spring.  Layering during the growing period.

Botanic information
Leaf: The ovate leaves have 3-7 deeply pinnate linear lobes with recurved margins and an obtuse apex. The pubescent upper surface is dark green and the underside is whitish-scaly. They are arranged alternately or in a cluster along the twiggy branches.

Flower: The bisexual cyathiform flowers have 5-ovate sepals and 5-rounded white petals with a cluster of the yellowish thread-like stamens in the centre. After the petals have fallen the persistent ovary has clusters of plume-like lavender styles that are up to 50 mm (2in) long. They are arranged singularly or in a small cluster of three appearing throughout summer.

Fruit: The persistent achene has pink-purplish feathery plumes attached and the small seeds are very viable but the plant may be reproduced vegetatively.
