Description

Prostanthera prunelloides is an erect to spreading shrub that typically grows to a height of 1.5–2 m (4 ft 11 in–6 ft 7 in) and has four-ridged, slightly aromatic branches. The leaves are egg-shaped to circular, 16–65 mm (0.63–2.56 in) long and 9–40 mm (0.35–1.57 in) wide on a petiole 3–14 mm (0.12–0.55 in) long. The flowers are arranged in groups on the ends of branchlets, each flower with bracteoles about 2.5 mm (0.098 in) long at the base but that fall off as the flower develops. The sepals are 5–6.5 mm (0.20–0.26 in) long forming a tube 3–3.5 mm (0.12–0.14 in) long with two lobes, the upper lobe 2–3 mm (0.079–0.118 in) long. The petals are white to pale mauve and 12–15 mm (0.47–0.59 in) long.[2]
