Crassula peploides is a small plant that has potential for covering ground by forming mats in sunny garden spots. The leaves grow in small, erect rosettes at branch tips. They are narrow, almost cylindrical or barrel-shaped, but flat on the inside surfaces and curving inwards slightly. The leaf surface is rough, sometimes with red mottling and a reddish or blue-green colouring, depending on growing conditions. The tips taper to a slightly rounded or pointed shape.
The trailing stems are pale red (iSpot; www.redlist.sanbi.org).
