Wild Flowers of Pittsburgh

Canada Goldenrod (Solidago canadensis)

Solidago-canadensis-2009-09-25-Oakmont-02

Goldenrods are the bees’ best friends. This one, which was blooming in late September, grew in front of a corrugated steel fence near a disused railroad siding in Oakmont. It may be common to the point of superabundance, but there is no more elegant wild flower than Canada Goldenrod.

From Gray’s Manual of Botany: S. canadensis L. Stem rather slender, 0.3-1.5 m. high, glabrous at least below, often minutely pubescent above; leaves narrowly lanceolate, thin, glabrous above, minutely pubescent on the nerves beneath, mostly sharp-serrate, the middle ones 6-13 cm. long, 5-18 mm. wide; heads tiny, crowded in recurved racemes and forming dense broadly pyramidal panicles; pedicels strongly pilose; involucral bracts linear, mostly attenuate, greenish-straw-color. (Var. glabrata Porter.) Thickets and rich open soil, Nfd. to N. Dak., s. to W. Va. and Ky. July-Sept.
