Isolepis prolifera is a tufted perennial sedge-like plant, and the species is distinct from grasses and rushes by its leafless stems and proliferating flower heads. It grows in damp places in temperate and subtropical regions of the Southern Hemisphere, and is mainly grown as a moisture-loving garden or pond-margin plant.

About

Isolepis prolifera is a species of flowering plant in the family Cyperaceae that grows in temperate regions of the Southern Hemisphere. It has leafless stems up to 90 cm (35 in) tall, and clusters of flowers that often proliferate into branches.

Where it grows

Isolepis prolifera is found in a number of countries around the world, although it is not clear where it is native, and where it is an introduced species. The International Union for Conservation of Nature considers it to be native only to South Africa, where it grows in the Eastern Cape, KwaZulu-Natal and Western Cape provinces. It is also widespread in New Zealand, occurring on the South Island, North Island, and on the Chatham Islands, and may be native there. In Australia, I. prolifera occurs in New South Wales, Victoria and Tasmania, as well as in the Mediterranean-climate region of Western Australia. It is also potentially native to Tristan da Cunha and Saint Helena, and has been introduced to France and California.
