Goldenrod is in the Sunflower family which is apparent when you get close enough to look at an individual flower head, but they are most impressive to me in large batches. Their particular shade of yellow stands out. In late summer, they are among the yellow-blooming species that seem most prevalent. I've always wondered why the majority of August blooms are yellow.To the average view, this probably looks like dirty or stagnant water. To me, the cyanobacteria remind me of our origins. Our ancestors some 3.5 billion years ago looked a bit like this.
