Narrow-leaf cattail is commonly found along ponds throughout North America, recognized by its tall, narrow sword-shaped leaves and the brown fuzzy cylindrical fruit that looks like a hotdog on a stick. It is so ubiquitous in wetlands that it was beleived by many to be native to North America. Our native species is Typha latifolia, which has broader leaves. Narrow-leaf cattail is now considered an invasive species, and it hybridizes with the native species. Its use in ponds is no longer recommended.
