G. E. Crow
Native probably to South America, this is a small, free floating aquatic with rosettes of densly hairy leaves ca. 10–15 cm in diameter that grows very quickly and can blanket substantial areas during the growing season. Though presumably unable to survive Michigan winters, it is commonly cultivated in water gardens and may be regularly re-established each growing season through dumping of excess plants into waterways, or perhaps accidental dispersal. Documented in 2015 in the Detroit River in Wayne Co., by B. Luukkonen and A. Spenski.
