The creeping saxifrage grows as a perennial herbaceous plant and reaches heights of 8 to 45 centimeters. It develops long thread-like runners with scale-like leaves. The stem is hairy glandular.
The basal leaves, which are distributed on the stem, are divided into a petiole and a leaf blade. The petiole is 15 to 21 inches long and hairy glandular. The leaf blade of the basal leaves is green on top, with silver-gray nerves and hairy glands and reddish on the underside. With a length of 1.5 to 7.5 centimeters and a width of 2 to 12 centimeters, it is almost heart-shaped, kidney-shaped or circular with a somewhat truncated, rounded or heart-shaped base, a blunt or pointed upper end and an irregularly notched-sawn shape Edge. The stem leaves and bracts are lanceolate with a length of only 6 millimeters and a width of 2 millimeters.
Generative characteristics
The loose, paniculate inflorescence contains 7 to 61 flowers.
The hermaphrodite flowers are zygomorphic and five-fold with a double flower envelope . The expanded or thrown back sepals are 1.5 to 3.5 millimeters long and 1 to 1.8 millimeters wide and ovate with three nerves and glandular hairy on the underside and on the edges. Two of the five white petals are characteristically longer than the rest. The two longer petals are 6 to 15 millimeters long and 2 to 4 millimeters wide and lanceolate-oblong, keeled with a pointed upper end. The three smaller petals are ovate and red or yellow with a length of 2 to 4.4 millimeters and a width of 13 to 2 millimeters. The ten stamens are 4 to 5.2 millimeters long. There is an almost ring-shaped nectar disc . The Upper constant, ovoid ovary is bright yellow. The two styluses are free along their entire length.
The capsule fruit opens with two fruit valves and contains many seeds.
In China, the flowering period extends from April to November, and the fruits ripen in the same months.

The number of chromosomes is 2n = 30, 36 or 54.
