Bukhara fleeceflower, Fallopia baldschuanica

Bukhara fleeceflower is a twining vine, more popular traditionally than currently for garden trellises. I find the name Bukhara curious. This plant originated in that general area of the world, but why focus on the fifth largest city in Uzbekistan? It is located on the silk road. Did Marco or one of the many other travelers through that area bring it from there to Europe? It was his writing that brought him to our attention, and separated him from the others. Perhaps he mentioned it? Anyway, some fanciful thoughts for a fanciful-looking flower. Plants with papillate flower stems are sometimes separated as F. aubertii. Either way this has been reported from CA, CO, MA, MD, MI, NJ, NM, NY, OR, PA, UT, VA, and WA. Cultivated, Leelanau Co MI, 9/13/12. Knotweed family, Polygonaceae.
