About

Astelia nervosa, also known as mountain astelia or, along with a number of other species, as bush flax, is a herbaceous plant native to New Zealand. A. nervosa has long, flexible, leathery leaves that are light green and grey in colour. The flowers are light brown to red in colour. The mature fruits are generally orange.

It is found in lowland to low alpine areas from the southern North Island south to Stewart Island.

Where it grows

Usually found in the uplands but is an occasional hydrophyte. Astelia likes soil that does not dry out during growing season as they have a high need for moisture in the soil, and they prefer full sun to partial shade. The plant prefers locations with an average monthly rainfall of at least 100 cm. Astelias are typically found in forest locality with a surplus of fog because this is where they flourish. Humus soil where Astelia plants occur is almost always moist, and consists almost entirely of organic matter.
