Wisconsin Blackberry

Description

Rubus wisconsinensis is an uncommon North American species of flowering plant in the rose family. It is native to the north-central United States (Minnesota, Wisconsin, Michigan, Iowa, Illinois). The genetics of Rubus is extremely complex, so that it is difficult to decide on which groups should be recognized as species. There are many rare species with limited ranges such as this. Further study is suggested to clarify the taxonomy.  Some studies have suggested that R. wisconsinensis may have originated as a hybrid between R. setosus and R. pensilvanicus.
