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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
