The leaves of all species of cattails look like large blades of grass. Broad-leaf cattail leaves are longer than the spike that carries the flowers and can reach lengths of 6 to 7 feet. As the name implies, their leaf blades are the widest of all the North American species, reaching up to 1 inch in width. Narrow-leaf and hybrid cattail leaves are considerably narrower, being only a few millimeters wide.
