Prostanthera incisa

Prostanthera incisa, also known as the Cut-leaf Mint Bush, is a species of flowering plant in the family Lamiaceae. It is endemic to Australia, specifically in the states of New South Wales and Victoria.

Description

Prostanthera incisa is a small shrub that typically grows to a height of 0.5 to 2 meters. It has narrow, elliptical leaves that are approximately 15-30mm long and 2-5mm wide. The leaves are dark green on top and paler underneath, with a strong minty aroma when crushed. The flowers are tubular, approximately 10-15mm long, and are typically a vibrant purple color, although white and pink varieties also exist.

Taxonomy

The species was first formally described by botanist George Bentham in 1834. The genus name Prostanthera is derived from the Greek words 'prostheke' meaning an appendix, and 'anthera' meaning anther, in reference to the appendage found on the stamens of plants in this genus. The species name 'incisa' is Latin for 'cut into', referring to the serrated edges of the leaves.

Distribution and Habitat

Prostanthera incisa is found in a variety of habitats, including heathland, woodland, and forest, usually in rocky or sandy soils. It is most commonly found in the coastal and near-coastal regions of southern New South Wales and eastern Victoria.

Cultivation

Prostanthera incisa is popular in cultivation due to its attractive flowers and pleasant aroma. It is a hardy plant that can tolerate a range of conditions, including frost and drought. It prefers a sunny or partly shaded position with well-drained soil. The plant can be propagated from cuttings or from seed, although the latter can be difficult to germinate.

Uses

In addition to its ornamental value, Prostanthera incisa has been used by Indigenous Australians for medicinal purposes. The leaves have been used to treat headaches and colds, and the plant is also used in bush food cooking for its minty flavor.

Conservation Status

Prostanthera incisa is not currently considered to be at risk in the wild.
