Wild Flowers of Pittsburgh

Coltsfoot (Tussilago farfara)

Every year we give the Coltsfoot flowers their honored place among the first wild flowers of spring. Here we have a good collection from a colony growing in open woods in Mount Lebanon, where they were blooming in early April. In these close-up pictures taken just as the flower heads were opening, we can see the individual star-shaped disk flowers clearly.

Gray describes the genus and the species:

TUSSILÀGO [Tourn.] L. COLTSFOOT. Head many-flowered; ray-flowers in several rows, narrowly ligulate, pistillate, fertile; disk-flowers with undivided style, sterile. Involucre nearly simple. Receptacle flat. Achenes slender-cylindric or prismatic; pappus copious, soft, and capillary. — Low perennial, with horizontal creeping rootstocks, sending up scaly scapes in early spring, bearing a single head, and producing rounded heart-shaped angled or toothed leaves later in the season, woolly when young. Flowers yellow. (Name from tussis, a cough, for which the plant is a reputed remedy.)

T. farfara L. — Wet places and along brooks, e. Que. to Pa., O.,and Minn. (Nat. from Eu.)
