Facts

Common wrinkle-leaved goldenrod gets its name from the wrinkled appearance of the leaves, which is due to indentations around the veins.

Subspecies and varieties

Solidago rugosa P. Mill. ssp. rugosa is the more common form, known from CT, MA, ME, NH, RI, VT. S. rugosa ssp. aspera (Ait.) Cronq. var. aspera (Ait.) Fern. is known from CT, MA, ME, NH, RI.

common wrinkle-leaved goldenrod.  19a. Solidago aspera Ait.; S. celtidifolia Small; S. rugosa

• CT, MA, ME, NH, RI, VT. Fields, roadsides, swamps, edges of wetlands.

1a.  Leaf blades thick and firm, low-serrate or crenate to subentire, subacute to short-acuminate at the apex; involucral bracts usually obtuse or rounded at apex (the innermost sometimes acute); capitula with (5–) 6–8 (–10) ray flowers; plants with relatively shorter 
and stiffer pubescence, occurring in relatively drier habitats 
 … 19a. S. rugosa ssp. aspera (Ait.) Cronq. var. aspera (Ait.) Fern.

1b.  Leaf blades thin to moderately thick, usually sharply serrate, short-acuminate to acuminate at the apex; involucral bracts subacute to acute at apex; capitula with (6–) 8–11 (–13) ray flowers; plants with relatively longer and softer pubescence, occurring in relatively wetter habitats 
 … 19b. S. rugosa ssp. rugosa

Subspecies aspera is known from CT, MA, ME, NH, RI. Subspecies rugosa is known from CT, MA, ME, NH, RI, VT. It is much more common on the New England landscape than ssp. aspera.

19×20. Solidago rugosa × Solidago sempervirens → Solidago ×‌asperula Desf. is a rare goldenrod hybrid known from CT, MA, ME, NH. It is known from coastal states where S. sempervirens comes into contact with S. rugosa at the upper limit of coastal marshes and beaches. It can be separated from the former by pubescent stems (at least on the upper portion) and from the latter by leaf blades with shorter teeth and less rugose veins. It can resemble S. latissimifolia, but the hybrid shows more hairs on the stems and ± sheathing petiole bases on lower leaves.
