Hoya carnosa makes faintly succulent shoots with smooth, pale gray, and bare surfaces that twine and climb. The perennial leaves are stalked with about 1 to 1.5 cm long stems. The blade is wide oval to longitudinal oval or heart-shaped. The leaves are slightly succulent, fleshy with a waxy glossy surface. The leaves, ovate or elliptical, are 3-5 cm wide and 3.5-13 cm long, with a petiole of about 1-1.5 cm. The spindle-shaped fruits measure 6 to 10 × 0.5 to 1.5 cm
