How to Grow

Cultivation

Grow as bedding, in containers that can be moved indoors over winter, or as a houseplant. Plant in moist but well-drained soil or peat-free, loam-based potting compost, and position in part shade or bright filtered light; direct sun may scorch the leaves. Water moderately when in active growth, and sparingly in winter. See houseplant cultivation for more advice

Propagation

Propagate by softwood cuttings using stem tips in spring or summer, rooting in peat-free cutting compost or water, then pot up into peat-free, loam-based potting compost
