features

Hoya carnosa makes weakly succulent shoots with a smooth, pale gray and bare surface that twist and climb. The shoots are initially soft, but later lignify. The perennial leaves are stalked with stems about 1 to 1.5 cm long. The blade is broad-oval to longitudinally oval or heart-shaped. The leaves are slightly succulent, fleshy with a waxy, shiny surface. The inflorescence is to 30-flowered, drooping or more or upright; it is designed as a stalked shamrock . The stem becomes about 4 cm long. The individual flowers are also stalked; here the stem measures 2 to 4 cm. The corolla has a diameter of 1.5 to 2 cm and is whitish to slightly pink in color. The corolla lobes are broadly oval to rounded triangular. The edge is bent over. Inside the surface is covered with papillae. The secondary crown is colored white. The interstaminal corolla lobes are pointed oval to lanceolate, the top is convex. The outer end is white, the inner end is colored red. The flowers have a strong smell and give off a sticky sap that hangs in drops on the flowers. The spindle-shaped fruits measure 6 to 10 × 0.5 to 1.5 cm.

The number of chromosomes is 2n = 22, less often 33.
