Thimbleberry (Rubus parviflorus) is common in western North America but only isolated populations exist in the Great Lakes region. At one time its range may have been uninterrupted, only to be broken up by repeated glaciations and climate change.
The species name, parviflorus, means small flowered in Latin. That is an obvious misnomer since this plant has one of the largest flowers in the Rubus genus.
