Prostanthera rotundifolia is a small shrub that typically grows to a height of 0.5 to 2.5 meters. It has round, aromatic leaves that are about 10 to 20 millimeters in diameter. The leaves are green on top and paler underneath. The flowers are tubular, about 15 to 25 millimeters long, and are typically purple or mauve in color, although white-flowered forms are also known.

Taxonomy

The species was first formally described by botanist Robert Brown in 1810. The genus name Prostanthera is derived from the Greek words 'prostheke' meaning an 'appendage' and 'anthera' meaning 'anther', referring to the appendage on the stamens of plants in this genus. The species name rotundifolia is derived from the Latin words 'rotundus' meaning 'round' and 'folium' meaning 'leaf', referring to the shape of the leaves.

Prostanthera rotundifolia is found in a variety of habitats, including heathland, woodland, and forest, usually in rocky or sandy soils. It is often found in the understorey of Eucalyptus forests.

Cultivation

Prostanthera rotundifolia is cultivated as an ornamental plant for its attractive foliage and flowers. It is also used in traditional medicine for its antimicrobial properties. The leaves can be used to make a tea that is said to aid digestion.

In its native range, Prostanthera rotundifolia is not considered to be at risk. However, like all native Australian plants, it is protected under the National Parks and Wildlife Act 1972.
