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 not usually required. There is no need to deadhead. Should survive outdoors in most areas especially if protected by a thick mulch. In very cold areas lift the crowns and store in a greenhouse, raising fresh plants from these each year
Propagation
Propagate by softwood cuttings taken in spring
Suggested planting locations and garden types
- Cottage and informal garden
- Cut flowers

Cut back to near ground level in the autumn.
