Typha latifolia has been found in a variety of climates, including tropical, subtropical, southern and northern temperate, humid coastal, and dry continental. It is found at elevations from sea level to 7,500 feet (2,300 m). Typha latifolia is an "obligate wetland" species, meaning that it is always found in or near water. The species generally grows in flooded areas where the water depth does not exceed 2.6 feet (0.8 meters). However, it has also been reported growing in floating mats in slightly deeper water. T. latifolia grows mostly in fresh water but also occurs in slightly brackish marshes. The species can displace other species native to salt marshes upon reduction in salinity. Under such conditions the plant may be considered invasive, since it interferes with preservation of the salt marsh habitat. Learn more about Cattail
