Japanese Knotweed or Mexican Bamboo (Fallopia japonica)
This pretty flowering plant has been dubbed an invasive plant and is illegal to sell in many parts of the USA due to it's ability grow rapidly. It is very difficult to eradicate, therefore it tends to choke out more desirable plants. This photo was taken in the back yard of my parents house in Kane PA.
