It is a shrub with oblong to lance-shaped leaves and red, yellow and orange flowers over an extended period.
The leaves are arranged in opposite pairs along the stems, 6–12 millimetres (0.2–0.5 in) long, lance-shaped to oval with a blunt tip and with their edges rolled under.
The leaves have obvious oil glands on their lower surface and have a pleasant lemon scent when crushed.
