Quick Guide: spring/summer, hardy, sun/semi-shade, height: 75cm/30in, width: 45cm/18in

Commonly known as leopard's bane, doronicums bring the first glow of colour to the mixed border in spring, and if regularly dead-headed may produce a second flush of flowers in the autumn. The yellow, daisy-like flowers are excellent for cutting.

GROWING Set out young plants in the autumn, in fertile, moist soil in sun or dappled shade. Remove faded flowerheads regularly. Cut the stems back in autumn.

PROPAGATION Divide established plants in the autumn, using only the healthy outer portions. Replant immediately.
