Portulacaria armiana (previously Ceraria armiana), also known as the whipstick-porkbush, is a succulent plant native to southwestern Namibia.[1]
It grows as a low shrub. It can be distinguished from its relatives by its large, grey-green waxy leaves, and its extremely tall inflorescence ("whipstick"), which rises unusually high (up to 8 meters).
Within the genus Portulacaria, it is most closely related to its sister-species Portulacaria namaquensis.[2]
Its natural habitat is the lower reaches of the Orange River valley of Namibia, near the border with South Africa. In this extremely arid, winter-rainfall area, it favours mildly acidic sands on high granite outcrops.
It grows in full sun in extremely well-drained soil, and can be propagated by seed or cuttings.[3]
