Genus

Pelargonium can be perennials, sub-shrubs or shrubs, sometimes succulent and mostly evergreen, with palmately lobed or pinnately divided leaves and clusters of slightly irregular, 5-petalled flowers

Name status

Accepted

Horticultural Group
Unique pelargoniums are shrubby perennials with often pungently scented, rounded, lobed or more deeply cut foliage and clusters of single, funnel-shaped white, pink, red, orange or purple flowers to 3cm across

How to grow

Cultivation

As with all pelargonium cultivation, plants enjoy good light and frost-free conditions. A regular high potash feed through spring and summer promotes flowering

Propagation

Propagate by softwood cuttings in spring or summer

Suggested planting locations and garden types
  • City and courtyard gardens
  • Patio and container plants
  • Flower borders and beds
Pruning

Cut back old plants by half in early spring to promote flowering; deadhead regularly

Pests

Generally trouble-free, but may suffer from aphids in spring

Diseases

Generally disease-free, but may be susceptible to grey moulds, pelargonium rust and pelargonium viruses
