Prostanthera ringens is a bushy shrub that typically grows to a height of 2 m (6 ft 7 in) with four-sided, hairy, densely glandular branches. The leaves are egg-shaped to oblong, 6–15 mm (0.24–0.59 in) long and 2–6 mm (0.079–0.236 in) wide on a petiole up to 3 mm (0.12 in) long. The flowers are arranged singly in leaf axils with bracteoles about 1 mm (0.039 in) long at the base. The sepals are 6–8 mm (0.24–0.31 in) long forming a tube about 5 mm (0.20 in) long with two lobes about 2 mm (0.079 in) long. The petals are 14–23 mm (0.55–0.91 in) and pale blue to greenish or yellow, forming a tube about 10 mm (0.39 in) long.[2][3]
