About
A clump-forming perennial reaching 80-9cm tall. Flowers are borne on upright, branched, leafy stems in late summer to early autumn and are made up of narrow, quill-like, butter yellow ray florets surrounding a central dark chocolate brown cone. The green, lance to oval-shaped, toothed leaves have a mild, sweet aroma and are softly hairy.
