Question
My house came with a patch of 2 meter tall goldenrod. I don't know if it is wild or planted. It is starting to bloom in late July after a lot of rain earlier in the month.
Answer
Dear jfc, the plant is likely Solidago altissima. This is a species with triple-nerved leaves and pubescent stems. To confirm this, I would need to know about the pubescence of the underside of the leaf--if it is pubescent across the surface (not just on the veins), then it is mostly likely that species. The involucral bracts will also be longer than in S. canadensis (when the capitula are present). Best wishes.
