It can grow to 1.5 m in height. The evergreen leaves are 5–10 cm long and 2–3 cm broad, produced in whorls of 4-7 starlike around the central stem. It climbs with tiny hooks at the leaves and stems. The flowers are small (3–5 mm across), with five pale yellow petals, in dense racemes, and appear from June to August, followed by small (4–6 mm diameter) red to black berries. The roots can be over 1 m long, up to 12 mm thick. It prefers loamy soils with a constant level of moisture.

Uses
Rubia cordifolia was an economically important source of a red pigment in many regions of Asia, Europe and Africa. It was extensively cultivated from antiquity until the mid nineteenth century. The plant's roots contain an organic compound called Alizarin, that gives its red colour to a textile dye known as Rose madder.
