Kalanchoe rotundifolia is a perennial , occasionally annual , completely bare, frosted plant that reaches heights of 20 to 200 centimeters. Their usually simple, stalk-round shoots are erect or basal prostrate. The leaves are petiolate to sessile. The almost cylindrical petiole is up to 1.2 centimeters long and easily detached from the shoot. The pale green or blue-green, elongated, lanceolate, elliptical, spatulate or triangular leaf blade is 1 to 8.5 inches long and 0.5 to 5.5 inches wide. Its tip is pointed to rounded, the base wedge-shaped. The leaf margin is entire, cupped, serrated, notched or more or less deeply three-lobed.

The lanceolate or triangular, pointed calyx lobes are 0.5 to 2 millimeters long and 1 millimeter wide. The deep red to orange corolla is yellowish to greenish in the lower part. The urn-shaped corolla tube, spherical in the lower part, is 6 to 10 millimeters long. Your lanceolate or elliptical, strongly pointed, spreading corolla lobes have a length of 2.5 to 5 millimeters and are 1 to 2.5 millimeters wide.
