La renouée du Japon = Reynoutria japonica = Fallopia japonica Polygonacées (Rhône, France)

classée invasive ; une vraie nuisible pour les milieux qu'elle envahit

it may be invasive, but in the photo it brings such great color to a colorless part of the world, the cement and sidewalk.

i lived in arizona for awhile where we had to beg things to grow. i prefer having an abundance that needs to be held back. (i totally get the problems of invasive plants however! we deal with English Ivy overtaking our wooded areas and killing trees, a constant struggle to keep it at bay.)

thanks for adding to my groups!
