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
Pest resistanceMay be susceptible to glasshouse whitefly and glasshouse red spider mite and whitefly
Disease resistanceMay be susceptible to virus diseases
