How to Grow

Cultivation

Pot up cuttings in spring, and restrict to three stems per plant. Stake (see staking perennials) and feed regularly. Put outside in a sunny position once danger of frost is past. For large blooms, disbud. Bring pots into frost-free conditions as it gets colder. After flowering, reduce watering, cut back and store in frost-free conditions

Propagation

In spring, propagate by basal softwood cuttings that were taken from stools overwintered in frost-free conditions
