Horticultural Group

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. Pinch out the growing tip when the plants are 15-20cm tall to encourage free-flowering, bushy plants. Staking and deadheading are not usually required. Plants should survive outdoors in milder areas especially if protected by a thick mulch. In 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
