Care notes
- Cultivation
- Grow in a sheltered site in full sun in fertile well-drained soil, enriched with organic matter and general purpose fertiliser. Water freely in dry weather. Pinching out the growing tip when the plants are 15-20cm tall to encourage free flowering bushy plants. Staking is usually required. There is no need to deadhead. In mild areas leave in the ground protected by a thick mulch. Elsewhere lift the crowns and store in a greenhouse, raising fresh plants from these each year
- Pruning
- Cut back to near ground level in the autumn, before lifting and storing for the winter
- Propagation
- Propagate by softwood cuttings taken in spring from shoots from stored stools
- Pest resistance
- May be susceptible to aphids and leaf miners which are common pests. Leaf and bud eelworms can damage stock that has not been heat-treated. Earwigs sometimes damage blooms. Capsid bug and glasshouse red spider mite are occasional pests
- Disease resistance
- May be susceptible to glasshouse grey mould, powdery mildews and chrysanthemum white rust
