Bransford, W.D. and Dolphia
Geranium robertianum L.
Herb Robert, Robert geranium
USDA Symbol: GERO
Paired, pink to lavender flowers on stalks rising in axils of intricately divided leaves on hairy, reddish, branching stems.
This European introduction, naturalized in North America, is an especially attractive member of the geranium family, but the leaves have an unpleasant odor when crushed. It is variously reported to have been named for Saint Robert of Molesme, whose festival date in April occurs at about the time the flowers bloom in Europe, or for Robert Goodfellow, who is known as Robin Hood.
