Common water-hyacinth is one of the world's most aggressive aquatic weeds, especially in the tropics, where it chokes slow-moving streams and ponds, altering habitats and out-competing native species. Native to Brazil, water-hyacinth was introduced to North America in 1884, and its control remains expensive and labor-intensive. It has been collected in Connecticut.
