HanksComment: Rørslett (2012) first showed a European G. robertianum in ultraviolet(1). Here is a North American example found in coastal New Jersey which exhibits a similar UV signature. The plant is native to both Europe and N. America and other regions of the world. Reference:1. Rørslett, B. (2012) Geranium robertianum L. (Geraniaceae) Herb Robert.

Another flower showed 7 petals. In all other respects the plant satisfied the characteristics of G. robertianum. Set 2 below contains an example of the normal 5-petaled flower.
