The Quarry Gardens are glowing right now with 14 species of goldenrod in various stages of bloom. If that seems like a lot, know that solidago, or goldenrod, is a genus of 100–120 species of flowering perennial plants in the aster family (Asteraceae), and most may be found in North America.

The most prominent species at the overlook platform is Gray goldenrod, Solidago nemoralis, seen above and in the highlight photo.

Nine species are QG legacies—found here in the pre-garden surveys of biota. Among those legacies is Pineywoods or Small’s goldenrod, Solidago pinetorum, pictured below, about 3 feet tall, discovered only weeks ago as a volunteer along the walk from the Visitor Center through the pine woods—a Nelson County first.

Other legacy goldenrods:

  • Tall goldenrod,Solidago altissima, (to 4 feet)
  • White goldenrod, Solidago bicolor
  • Blue-stemmed goldenrod, Solidago cassia
  • Slender goldenrod, Solidago erecta 
  • Gray (or Field) goldenrod,Solidago nemoralis
  • Anise-scented goldenrod, Solidago odora
  • Stiff goldenrod,Solidago rigida var. rigida
  • Wrinkle-leaf goldenrod, Solidago rugosa

The Slender goldenrod at left is definitely a legacy but the Stiff goldenrod at right, found in the overlook prairie, might have sneaked in with purchased seeds of other plants.

​New to the site are five more species—native to the immediate area—that Rachel and her CUH crew have added:

  • Early goldenrod, solidago juncea, greets visitors from the prairie planting at the entrance gate.
  • Showy goldenrod, Solidago speciosa, may be found among the thousands of plants in the prairie over the original filled-in quarry pit between the two quarry pools.
  • Stout goldenrod, Solidago squamosa, is in the North Quarry’s waterside pollinator patch.
  • ​Zig-zag goldenrod, Solidago flexicaulis,may be found in the dry shade near the Whispering Waters

They are often difficult to distinguish from one another

​G​oldenrods are among the most important late-season pollinator plan​t. Honeybees collect ​the nectar for winter, and other bees use the pollen to supply late-season nests.

​No honeybees in this ​photo, but at least a dozen species of bees and wasps were working the plants when it was taken.


Here are some things from Wikipedia of interest about goldenrod:

  • Although frequent handling of goldenrod and other flowers by florists can cause allergic reactions, goldenrod is inaccurately blamed for hay fever: the blame for that lies with the ragweed that often grows in proximity and blooms at about the same time.
  • Goldenrod does make a spicy honey, but it sometimes has a rank odor and taste until fully processed (by bees). It is not a big commercial success, but apparently has its followers.
  • Thomas Edison and Henry Ford experimented with growing goldenrod for its rubber content before and during World War 2, anticipating a need for synthetic rubber. Ford even gave Edison a Model T with tires made of it in late 1920s. After Edison died in 1931, Ford enlisted the aid of Washington Carver, a well-known agronomist, and they succeeded in producing a hybrid goldenrod that yielded as much as 12 percent rubber. Unfortunately, it was not very good rubber, and by the time that first Carver and then Ford died by 1947, the project was abandoned.
