Cattail
Also known as: Typha latifolia, Typha domingensis
Cattails (Typha latifolia and Typha domingensis) are native to most of the United States. They provide nutrient uptake, wading-bird habitat, and shoreline erosion control — until they don't. Cattails reproduce through rhizomes (underground stems), not just seed. Cutting only the visible stalks signals the rhizome network to send up denser regrowth. The two-cut rule — cut below the waterline, cut twice in one season six weeks apart — actually reduces coverage. A managed 3–6 ft fringe is healthy; a 12 ft wall covering 50%+ of the shoreline is a problem.
