Geographical Distribution of Pelargonium in Africa. Source Wikipedia. Updated on 26th March 2019.
General Information and Agronomic Aspects
Pelargonium sidoides is indigenous to South Africa and Lesotho but now also grown commercially in Kenya.
The pelargonium is a tender evergreen perennial, however commercial interests are based on root extracts of this medicinal herb.
Climatic conditions, soil and water management
Pelargoniums like a sunny exposure, but in very hot areas they benefit from partial shade. They grow well in average soil that is well drained. They are very drought resistant.
Propagation and planting
Propagation is from cuttings, sometimes from seeds. Cuttings can be taken any time of the year except for the coldest months. Choose a compact side shoot about 10 cm long and pull off a small "heel". Remove the lower leaves and press into wet sand. Keep protected and damp until rooted. Plant 90 cm apart, as the rose-scented varieties grow very quickly (Margaret Robert's A-Z Herbs).
