Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water sparingly once established. Allow the soil to dry out completely between waterings. Overwatering is detrimental and can lead to root rot, especially in well-draining soils.
Reduce watering significantly during winter dormancy to prevent moisture buildup.
Prune lightly after flowering to maintain shape and encourage bushier growth. Remove any dead or leggy stems to improve air circulation and appearance.
Avoid heavy pruning, as it can stress the plant and reduce future blooms. Aim for a natural, rounded form.
Propagate from semi-ripe cuttings taken in summer. Insert cuttings into a well-draining compost mix and keep moist and warm. Alternatively, sow seeds in autumn or spring in a cold frame.
Germination can be erratic, so patience is key.
Repot young plants annually or when root-bound, preferably in spring. Use a gritty, well-draining compost mix.
Established plants are generally happier in their pots and can be repotted less frequently, or even grown in situ if conditions are suitable.
