This morning I was walking in Saint-Bruno national park in Quebec, Canada and I happened upon this large patch of ground cover. It was particularly striking as it seemed to be an evergreen herbaceous plant. Apart from conifers I don't remember seeing green anywhere at this time of year in the woods or forests of Quebec.
This leads me to believe it might not be an indigenous plant.
It was located in a zone 5B small deciduous forest that is near a small lake and very close to a suburban area.
