Many goldenrod species are aggressive/invasive, giving the whole genus a bad reputation. This species is a good clump former, not a runner, and I've never seen it self-sow aggressively.

This is a woodland species and much more shade tolerant than most goldenrods, most of which are meadow/prairie/field plants.

My biggest customer has several spots in her large backyard of this species growing in part-shade with a whole bunch of other plants around them, causing them to lean more than they would. Pretty perennial for yellow late summer and early fall bloom and bluish-green foliage. Liked by a good number of bees and other insect pollinators. It does self-sow around the yard.

My only experience with this plant is seeing it in bloom in the local woods. It is very attractive, differing from the typical goldenrod in growth habit. The flowers are carried along the stem in the leaf axils. They are a rich golden yellow against dark green leaves and a bluish stem. The plant is much more subdued in structure than other goldenrods, and seems to grow well in shady conditions. I hoped to collect some seed and try growing in my shady garden. I will followup with my results.
