It has also been introduced to Australia.Many parts of the Typha plant are edible to humans. The starchy rhizomes are nutritious with a protein content comparable to that of maize or rice. They can be processed into a flour with 266 kcal per 100 grams. They are most often harvested from late autumn to early spring. They are fibrous, and the starch must be scraped or sucked from the tough fibers.
