Pseudowintera colorata

Pseudowintera colorata, also known as the New Zealand pepper tree, horopito or winter's bark, is a species of evergreen shrub in the Winteraceae family. It is endemic to New Zealand and is notable for its biological and cultural significance.

Description

Pseudowintera colorata is a small tree or shrub that grows up to 10 meters in height. The leaves are elliptical in shape, ranging from 2 to 8 cm in length. They are notable for their red coloration, which is more pronounced in exposed situations. The leaves also have a strong, peppery taste, which has led to its use as a culinary herb.

Distribution and habitat

Pseudowintera colorata is found throughout New Zealand, from sea level to the subalpine zone. It is most common in upland and mountain forests, but can also be found in lowland areas. It prefers well-drained soils and is tolerant of both sun and shade.

Ecology

The leaves of Pseudowintera colorata contain a compound called polygodial, which has antifungal and antibacterial properties. This makes the plant unpalatable to many herbivores, and it is often one of the last plants standing in areas of heavy browsing.

Uses

The Maori people of New Zealand have traditionally used Pseudowintera colorata for medicinal purposes. The leaves were chewed or boiled to treat stomach ache and diarrhoea, and the bark was used to treat skin diseases. Today, the plant is used in the production of a range of health products, including herbal teas and supplements.

Conservation

Pseudowintera colorata is not currently considered to be at risk of extinction. However, like all native New Zealand plants, it is protected under the New Zealand Biodiversity Strategy.
