The stems are erect to sprawling and branched, growing 50-120 cm in height, with the lower sections being woody.
Dark green, diamond-shaped leaves are arranged alternately along the stem, 4-8 cm long, with petioles that are less than a third of the length of the leaves. They are paler below, with short, grayish hairs. The top half of the leaves have toothed or serrated margins while the remainder of the leaves are entire (untoothed).
The petioles have small spines (stipules) at their bases.
Delicate flowers occur singly on flower stalks (peduncles) that arise from the area between the stems and leaf petioles. They consist of five petals that are 4 to 8 mm long, creamy to orange-yellow in color, and may be somewhat reddish in the centre.
