It is a perennial plant with short spreading roots, erect to decumbent stems 15–90 cm (6–35 in) high, with fine, threadlike, glaucous blue-green leaves 2–6 cm (3⁄4–2 1⁄4 in) long and 1–5 mm (0.04–0.20 in) broad. The flowers are similar to those of the snapdragon, 25–33 mm (0.98–1.30 in) long, pale yellow except for the lower tip which is orange, borne in dense terminal racemes from mid summer to mid autumn. The flowers are mostly visited by bumblebees. The fruit is a globose capsule 5–11 mm (0.20–0.43 in) long and 5–7 mm (0.20–0.28 in) broad, containing numerous small seeds.
