About the guide
Garden geranium is on the Alert List for Environmental Weeds, a list of 28 non-native plants that threaten biodiversity and cause other environmental damage. Although only in the early stages of establishment, these weeds have the potential to seriously degrade Australia's ecosystems.
Garden geranium, a member of the South African geranium family, was originally planted in gardens for its ornamental value in southwestern Western Australia. It has since become a naturalised weed in peppermint woodland (Agonis flexuosa) 2 km inland from Hamelin Bay in the Margaret River region. Its introduction to Australia is estimated to have occurred in the early 20th century, when a timber settlement was in place.
