How to grow

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

Propagation

Propagate by softwood cuttings taken in spring from shoots from stored stools

Suggested planting locations and garden types
  • Cottage and informal garden
  • Cut flowers
  • Flower borders and beds
Pruning

Cut back to near ground level in the autumn, before lifting and storing for the winter

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

Diseases

May be susceptible to glasshouse grey mould, powdery mildews and chrysanthemum white rust
