Discussion

Packera tomentosa is common throughout most of its range. The basal and proximal cauline leaves are held at about 45 degrees to the stems.

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.
