description
Portulacaria armiana grows as a 50 to 70 centimeter high subshrub with a yellowish brown and peeling bark. The small trunk reaches 3.5 centimeters in diameter. On the gray-green, 9 to 12 millimeter thick, shoots on a 2 to 5 millimeter long stem are obovate to ovate, succulent leaves. These are 3 to 7 inches long and 3 to 3.5 inches wide. The leaf base is wedge-shaped, the leaf tip rounded and the edge slightly wavy.
The upright inflorescence becomes 3 to 5 meters (sometimes up to 8 meters) high and has many delicate, upward-pointing branches. These are 5 to 10 cm and are provided with leaves similar, 3 × 1.4 cm large bracts occupied. Sepals 5 millimeters long are formed on the white flowers. The five elongated petals are 2.5 to 3 millimeters long.
