Mentha australis

Mentha australis, also known as the Australian mint, is a species of mint native to Australia. It is a perennial herb that grows in damp or wet habitats, including swamps and riverbanks.

Description

Mentha australis is a robust, aromatic herb that grows up to 50 cm in height. Its leaves are opposite, lanceolate to ovate, and range from 2 to 6 cm in length. The plant produces small, white to lilac flowers in summer and autumn. The flowers are arranged in whorls around the stem, forming a terminal spike. The fruit is a small, brown nutlet.

Distribution and habitat

Mentha australis is found throughout Australia, with the exception of the arid interior and the coldest mountain regions. It is particularly common in the eastern states, where it is often found in wetlands and along watercourses. The plant prefers damp or wet habitats and is tolerant of both sun and shade.

Uses

The leaves of Mentha australis are used in traditional Aboriginal Australian medicine and are also used as a culinary herb. The plant has a strong minty aroma and flavour, similar to that of peppermint and spearmint. It can be used fresh or dried in a variety of dishes, including salads, sauces, and teas.

Cultivation

Mentha australis is easy to grow and can be propagated from seed or by division of the rootstock. It prefers a moist, well-drained soil and a position in full sun or partial shade. The plant can be invasive and may need to be contained to prevent it from spreading.

Conservation status

Mentha australis is not considered to be at risk in the wild. However, like all native plants, it is protected under state legislation and cannot be collected from the wild without a permit.
