Did you know there is a native goldenrod that thrives in the shade? Zigzag Goldenrod produces long arching stems dotted along their lengths with clusters of yellow flowers. Lovely in a woodland garden. Goldenrods as a group are the top keystone species in Washtenaw County, as they support 135 species of butterfly and moth caterpillars that provide food for a range of other animals. Part-shade to shade; medium-dry to medium moisture. Blooms Aug.-Oct., yellow.
