Pterostylis lortensis is a small, deciduous terrestrial orchid from south-west Western Australia that grows from an underground tuber and flowers in late winter and spring. It is a wild species of winter-wet sites rather than a common garden plant, so growing it means reproducing that seasonal cycle.

About

Pterostylis lortensis, commonly known as the Lort River snail orchid, is a species of orchid endemic to the south-west of Western Australia. Non-flowering plants have a rosette of leaves flat on the ground but flowering plants usually lack a rosette and have a flowering stem with leaves and a single pale green and white flower with narrow, club-like lateral sepals.

Where it grows

The Lort River snail orchid usually grows in winter-wet places, often amongst sedges. It occurs between Boxwood Hill and Israelite Bay in the Esperance Plains biogeographic region.
