Himalayan Balsam (Impatiens glandulifera)Observer
colleen2Description
This is a terrible first entry! I didn't have my phone on me to take a picture of this plant in situ, and I didn't note if the leaves were opposite or alternate. It was in a ditch in a rural-residential area. I believe it is some kind of non native garden escapee. Any thoughts?
