Packera cynthioides
Packera fendleri
Packera cynthioides blooms later than other Packera species at the same latitudes. It is noted by collectors as usually growing on north- or west-facing slopes in limestone-derived soils. Its cauline leaves are well developed and held at a shallow angle to the stem, giving the plant a more “leafy” aspect than other members of the genus.

Packera fendleri is abundant, almost weedy in the southern Rocky Mountains. It thrives in a wide range of elevations and in a wide variety of habitats; flowering times vary. It frequently grows in close association with other species of Packera and may hybridize with them.
