Hylotelephium erythrostictum reaches on average a height of 30–70 centimetres (12–28 in). The stem is simple and the leaves are opposite, sessile, oblong, and succulent, about 5–7 centimetres (2.0–2.8 in) long. The flat cymes bear many white or pale pink tiny flowers of about 1 centimetre (0.39 in) of diameter, with lanceolate petals. The flowering period extends from September through October in the Northern Hemisphere.
