Pelargonium is a genus in the family Geraniaceae with more than 250 species, most of which are found in Southern Africa and especially in the winter rainfall area. Some of them are geophytes with a subterranean stem tuber and often root tubers as well. Many of them are from very dry areas and may appear only in a year when there is adequate rainfall. They need to be grown in well-drained slightly acidic soil in an open sunny location. On this page we will only include the geophytic species.
Tuberous Pelargonium was a topic of the week in August 2004. To read David Victor's very interesting introductions, see Part 1 and Part 2
