A. J. Miller-Rushing and R. B. Primack
What Thoreau Said: Smilax glauca in blossom, running over the shrubbery. Honlcenya peploides, sea sandwort, just out of bloom on beach. The thick-leaved and densetufted, upright plant Salsola Kali, saltwort, prickly and glaucous, ill bloom. Beach pea (hathyrus maritimus) going out of bloom ... Seaside goldenrod (Solidago sempervirens) not nearly yet.
--July 7, 1855
Thoreau described these plants during a vacation to Cape Cod for the July 4 holiday in 1855. He also wrote down that fishermen in Provincetown were selling fresh lobsters for two cents apiece!
Still abundant, but flowering times are shifting. Primack and Miller-Rushing noticed that climate change affects different goldenrod species in different ways âÂ some flower earlier, and some have no change.
