Broadleaf Cumbungi

Broadleaf Cumbungi (Typha orientalis) is a fast-growing perennial in the cattail family, Typhaceae. It grows as a tall waterside plant, reaching up to 3 metres, and is adapted to full sun and consistently wet or waterlogged ground. It tolerates light sandy, medium, and heavy clay soils, though it is not drought resistant. Its natural range is broad, spanning much of East Asia, including China, Japan, Korea, Manchuria, Mongolia, and the Philippines, as well as parts of Southeast Asia and large areas of Australia and New Zealand. It also occurs on islands such as Taiwan, Sakhalin, Norfolk Island, and the Kermadec Islands, and has been introduced to the Chatham Islands. In these settings it typically grows in marshes, along river and lake margins, and in other shallow freshwater habitats. The plant is edible across its native range, with the flowers, leaves, pollen, roots, seeds, shoots, and stems all used. These parts are reportedly eaten raw or cooked, often boiled or steamed to improve texture and flavour. Beyond food, broadleaf cumbungi is valued for fibre and weaving material, and its fast growth and dense stands make it useful for biomass and erosion control along wet banks. Because it can resemble other cattails and grows in wet environments, anyone considering harvesting it should identify it with certainty and gather from clean water, as wild aquatic plants can accumulate contaminants.
