It's been Solidago season here for a while, but fortunately it lasts a long time, so this post is still timely.
I have fond memories of Solidago, goldenrod being one of the first plants I remember learning a name for, and particularly one occasion when I came across a small but steep slope (a hill next to a ditch, if I remember correctly) that had goldenrod growing all up and down it. Though I was less impressed with the plant than I was with the number of pollinators, as I recall.
The only thing I don't like about them is that the bright golden yellow color is fleeting, and turns very quickly to a dull crappy brown, which makes everything look that much deader and sadder. And since it's the end of the summer, things already look pretty damned dead and sad. I suppose we can't really hold the Solidago responsible for summer ending, though.
I mean, we could hold them responsible, but it would be unfair. I'm sure they're not happy about it.
