editGoodenia bicolor is an annual or ephemeral herb that typically grows to a height of 40 mm (1.6 in) and has foliage with soft hairs. The leaves are lance-shaped to egg-shaped with the narrower end towards the base and irregular teeth on the edges, up to 20–50 mm (0.79–1.97 in) long and 6–20 mm (0.24–0.79 in) wide. The flowers are arranged in racemes up to 300 mm (12 in) long on a peduncle 2–5 mm (0.079–0.197 in) long with narrow elliptic bracteoles 2 mm (0.079 in) long at the base, each flower on a pedicel 2 mm (0.079 in) long. The sepals are narrow egg-shaped, 1.5 mm (0.059 in) long and the corolla is yellow or yellow and purple, 5–8 mm (0.20–0.31 in) long, the lower lobes of the corolla about 3 mm (0.12 in) long with wings about 0.8 mm (0.031 in) wide. Flowering occurs from March to June and the fruit is an elliptic capsule 3–4 mm (0.12–0.16 in) long.[2][3]
