Narrowleaf Cattail
It is a perennial herbaceous plant of genus Typha. This cattail is an "obligate wetland" species that is commonly found in the northern hemisphere in brackish locations.
The plant's leaves are flat, very narrow (¼"–½" wide), and 3'–6' tall when mature; 12–16 leaves arise from each vegetative shoot. At maturity, they have distinctive stalks that are about as tall as the leaves; the stalks are topped with brown, fluffy, sausage-shaped flowering heads.
It has been proposed that the species was introduced from Europe to North America. In North America, it is also thought to have been introduced from coastal to inland locations.
