About
A biennial or short-lived perennial, to around 50cm high in flower, forming a low mound of lobed and toothed green leaves. Leafy, branching, upright stems bear clusters of bright yellow, poppy-like flowers that open in succession from late spring to late summer, followed by long, silver haired seed capsules that explode when ripe to scatter seed.
