Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water regularly, keeping the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings. Reduce watering in cooler months or when the plant is dormant.
Good drainage is crucial to prevent root rot.
Prune back leggy stems in late spring or early summer to encourage bushier growth and more flowers. Deadhead spent blooms to promote continuous flowering.
Light pruning can be done anytime to maintain shape and remove dead or damaged foliage.
Propagate from stem cuttings taken in spring or summer. Dip the cut end in rooting hormone and plant in moist potting mix.
Alternatively, it can be propagated by seed sown in spring, though cuttings tend to produce plants true to type.
Repot young plants annually in spring to provide fresh soil and more space for root growth. Mature plants can be repotted every 2-3 years or when rootbound.
Use a well-draining potting mix and a pot that is only slightly larger than the current one.
