Pelargoniums are indeed a varied group, and Pelargonium oblongatum is one of the more unusual species. Over time in forms a large cuadex at its base, an attraction without it even flowering. A cuadex is a thickened woody stem that stores water.
It will flower, usually in late winter, to spring. Pretty pale yellow flowers held well above the caudex make a fascinating display.
A little shade in the afternoon and a frost free position, moist but well drained. If you are going to grow this, we suggest a container where conditions can be monitored and the wonderful caudex of Pelargonium oblongatum can be displayed.
Propagation is from seed or by cuttings. Originally from South West Africa (Namaqualand.) , this is a rare species you may need to grow from seeds, if you can find them.
The best places to buy rare species will be at Pelargonium and Geranium garden show, held annually in most states. See our garden show and plant fair index for details.
