Fallopia japonica, that’s the scientific name for Japanese knotweed. It has got to be the most vigorous, invasive plant that I have ever seen in an urban setting. Everyday that I walk to work, I pass some. It doesn’t matter which route – there it is pushing up through the pavement. And at this time of year, the dry stalks pushing up through the asphalt are clear and stark; no, lush, green growth covers this slow motion drama.
New growth – coming from the crown.
This plant grows all over Nova Scotia and there is a wealth of information online. From images to scientific papers like this one submitted for a MSc at Dalhousie University.
