  • Question

    Working on the goldenrods on the Joppa Flats property in Newburyport. Could this be S. canadensis? The teeth on the leaves of S. ulmifolia seem bigger. Not sure of the importance of the branching of the stem.

    Answer

    Dear chaffeemonell, you are certainly in the correct group. You have either Solidago canadensis or Solidago altissima, which you can separate by measuring the flower heads or examining the density and distribution of hairs on the lower side of the leaf. I hope this is helpful.
