Here's the best of the story! The prelude involves purple loosestrife, a well known, beautiful but hated invasive from Eurasia. Winged loosestrife is closely related, but is native. In fact, there are several native loosestrifes with pink/purple flowers. They grow in similar habitats, often with the invader. Winged is mostly seen in fens, and is very nicely in bloom now around here. So it's a decorative plant of fens that we can enjoy without guilt, it helps clean our water, and the Cherokee used an infusion of it for kidney problems. It grows in AL, AR, CO, CT, FL, GA, IA, IL, IN, KS, KY, LA, MA, MD, ME, MI, MN, MO, MS, MT, NC, NH, NJ, NY, OH, OK, PA, RI, SC, SD, TN, TX, VA, VT, WI, WV, WY, and ON. Monroe Co MI, 7/22/11. Loosestrife family, Lythraceae.
