Kalanchoe sexangularis, also known as bushveld kalanchoe, six-angled kalanchoe, or red-leaved kalanchoe, is a species of the succulent genus Kalanchoe, in the family Crassulaceae that is native to Southern Africa.

Description
Leaves
Flowers

Kalanchoe sexangularis is a succulent, perennial that reaches heights of 20 to 100 centimeters. Its single or few, simple, upright, round, reddish shoots are somewhat two-to-six-sided and arise from a woody base. The fleshy leaves are more or less stalked. The rutty petiole is 4 to 45 millimeters long. On the lower leaves it does not encompass the stem, but on the upper leaves it is clearly encompassing the stem.

The broadly elliptical, elongated or egg-shaped, green to deep ruby-red (in full sun) leaf blade is 5 to 13 inches long and 3 to 8 inches wide. Their tip is rounded or blunt. The base of the lower leaves is heart-shaped, that of the upper is wedge-shaped. The leaf margin is roughly notched or wavy-notched or with one to four bluntly toothed lobes.[1]
Inflorescences

A winter-bloomer, its inflorescence consists of flat-topped panicles up to 30 centimeters in length. The upright, green-yellow to bright yellow flowers are on 2 to 7 millimeter long peduncles.

The green calyx tube is 0.5 to 2 millimeters long. The triangular, pointed calyx lobes are 1.5 to 2.2 millimeters long and about 1.2 millimeters wide. The pale pink, square-cylindrical to almost pyramidal corolla tube is enlarged in the lower half and 8 to 13 millimeters long. Their salmon-colored, broadly egg-shaped to almost circular corolla lobes are narrowed or rounded at their tip and have a length of 2 to 4 millimeters and are 1.5 to 3 millimeters wide. The stamens are attached to the tip of the corolla tube. Upper stamens protrude from the flower. The almost circular anthers are 0.4 to 1 millimeter long. The linear-lanceolate, pointed nectar flakes are 1.6 to 4 millimeters long. The carpel has a length of 6.5 to 10 millimeters. The stylus is 1.7 to 4 millimeters long.[2]

The seeds reach a length of 1 to 1.3 millimeters.
Distribution

Kalanchoe sexangularis is common in Zimbabwe, Mozambique and South Africa on rocky slopes in the shade or partial shade of trees or shrubs in bushland.
