You can see here what I mean about the goldenrod. I'm not good enough at quick identification to tell you if this is Prairie Goldenrod or Canada Goldenrod or another species, but this is as yellow as it gets and the brightness fades quickly like the plants in the background here.
Between the bad press given to goldenrod, and the happy beaming face of the Maximilian Sunflower, I've got to choose the sunflower every time. And so, it seems do the bees. The only insect I've ever seen on goldenrod around here are the goldenrod soldier beetles.
