About plant names...

Geraniums are natives of Europe and Asia. Geranium ‘Rozanne,’ originally found growing in Donald and Rozanne Waterer's retirement garden in Somerset, England, was cultivated and sold for gardens. It is a natural hybrid of G. wallichianum ‘Buxton’s Variety’ x G. himalayense. It is not found in the wild.

Identification: Plants form mounds 18-24" (45-60 cm) in height. Deeply divided leaves are 1-2" (2.5-5 cm) around. Purple or blue-violet flowers appear singly or in small clusters, each with five rounded petals.
