About
A bushy annual, up to 50cm high, with rounded, shield-shaped ('peltate') leaves up to 8cm across, edged with tiny teeth where the veins meet the leaf margin. Rich orange or reddish orange flowers, with pointed tips to the petals and sometimes with purple veins or with red blotches at the base, are borne singly in the leaf axils from early summer into autumn.

Care notes
CultivationBest grown in poor, well-drained soil; if the soil is too rich foliage will be produced at the expense of flowers. Will tolerate light shade but flowering is better in full sun
PruningNo pruning required. Deadhead to encourage further flowers
PropagationPropagate by seed, sown under glass in spring and planted out after danger of frost has passed. May self-seed in place in good conditions, but germination is often too late to produce good flowers
