About Prostanthera decussata F.Muell.
Prostanthera decussata, commonly known as dense mintbush, is a dense, compact, strongly aromatic shrub that usually reaches a maximum height of 2 meters (6 feet 7 inches). Its leaves are egg-shaped, measuring 4 to 7 millimeters in length and 1 to 3.5 millimeters in width. The leaves lack a stalk or sit on a petiole that is up to 0.6 millimeters long; they are dark green on the upper surface and paler on the underside. Flowers grow in leaf axils near the tips of branchlets, with 2.5 to 3 millimeter long bracteoles at their base. Sepals measure 3.5 to 4 millimeters in total length, forming a tube 1 to 1.5 millimeters long with two lobes, where the upper lobe is 2 to 2.5 millimeters long. Petals are mauve to violet, occasionally pinkish, and 6 to 8 millimeters long. This species flowers from October to March. It grows in heath, forest, and woodland habitats across the eastern half of Victoria, the Australian Capital Territory, and mainly the south-eastern part of New South Wales.
