How to grow

Cultivation

Will grow well in a frost-free environment, in well-drained fertile neutral to alkaline soil, preferably in full sun but will tolerate some partial shade, in borders or containers. Irrigate moderately from spring to summer, and sparingly in winter allowing the compost to dry up between waterings. Apply a balanced liquid fertilizer during the growing season and switch to a high potassium fertilizer when flowering starts. Overwinter in containers before the first frost in autumn. See Pelargonium cultivation for further advice.

Propagation

Propagate from softwood cuttings from spring to autumn.
