Question
Goldenrod in Dutchess County NY, similar to Solidago gigantea, but leaves are far larger (on average between 6 and 8" long, and 1 and 2" wide), have only one prominent vein, are nearly glabrous (I counted six hairs on the veins on one leaf), and of a sample of leaves from 14 plants, this had an average of 12.4 teeth, while S. gigantea had an average of 19.5. Plants are clonal and lack basal leaves. Flowering full three weeks later than S. gigantea. Seems to grow only in and around streams.
Answer
Joshuaharkness, the short answer is: I can't identify the goldenrod from the information provided. I would need to see the involucral bracts and have a measurement of the length, and have a better idea of the number and size of disk and ray flowers. If you would like to send a specimen to me, feel free to email me at ahaines@nativeplanttrust.org and we can get this species identified for you. Best wishes.
