Description.
An upright or clump-forming herb or sub-shrub, occasionally reaching 60 centimetres in height. Leaves are silver-grey and densely hairy. Each of the many branches carries a single yellow, √ębutton√≠-like compound flower. Flowers are followed by a feathery crown of seeds, each of which possesses a plume of bristles which enables it to disperse by wind.
Propagation.
Seed germinates without pre-treatment but seed quality appears to be variable and germination rates are correspondingly low.
Flowering.
Chiefly spring and summer, but may produce some flowers year-round.
Locations.
Belfrayden. Grows in heavy soils on flood-plains.
