Piaranthus decipiens is very widely distributed around the arid northern and eastern edges of the Kalahari Desert and this includes parts of Namibia and Botswana where it is occasionally found under trees and shrub.
South African records include the Northern Cape areas of Prieska, Vryburg, Mafikeng and Schweizer-Reinecke
The succulent decumbent stems can grow up to 15 cm long but are usually shorter. The flowers appear in small numbers near the tips of younger stems and are usually brownish becoming paler in the tube. There is quite a bit of variation in the colouring and patterns of the flowers though.
Propagation is from seed or cuttings.
