Pelargonium peltatum (L.) L'Hér. ex Aiton
Pelargonium peltatum, commonly known as ivy-leaved geranium, is a succulent climber.
Pelargonium peltatum was already described and the name validly published by Carl Linnaeus. It was Charles Louis L'HÃ©ritier de Brutelle, however, who reclassified it into todays valid botanical systematics in 1789.
Pelargonium peltatum is a species in the genus Pelargonium which contains approximately 62 to 1479 species and belongs to the family of the Geraniaceae (Geranium Family). The type species of the genus is Pelargonium hirsutum.
The climbers reach heights of 50 to 200 centimetres. The plants reach a width of 30 to 60 centimetres.
Pelargonium peltatum is evergreen. The mid-green, simple leaves are alternate. They are palmately lobed, entire and petiolate. The surface of the leaves is glabrous.
Flowers and Fruits
Pelargonium peltatum produces umbels of pink five-stellate flowers from April to October.
The climbers produce schizocarps.
Pelargonium peltatum is native to South Africa, Lesotho and Swaziland.
The climbers prefer a sunny situation on fresh to moist soil. The substrate should be sandy loam. They tolerate temperatures down to -7Â°C (USDA zone 9). Under glass use loamy potting compost.
In summer the plants prefer protection from hot midday sun. In winter the plants prefer not too bright light.

Maintenance and Propagation
- Remove withered flowers.
- Repot as necessary at the beginning of the growing season.

- Water moderately in summer, give little water in winter.
- Lightly cut back at the beginning of the growing period.

Pests and Diseases
Distorted, discoloured or dead leaves and flowers are a sign of a bacterial infection. Generously cut out affected parts. Improve hygiene and control insects that may spread the infection.
Sudden wilting and pale green discolouration indicate a fungal infection (phytophthora). Remove infected plants. Avoid by improving drainage and over-fertilization.
