Geranium robertianum: flowers

Geranium robertianum, known in English as herb Robert, redshank, bloodwort, fox geranium, or red robin, and in French as herbe à Robert, is an annual or biennial native to North America. Unlike the plants commonly known as "geraniums" (which are really Pelargoniums), this wild geranium has finely divided somewhat fern-like leaves and single dainty five-petaled pink flowers.

I suppose it's cheating to include this photo in this blog as it was taken in Almonte, in eastern Ontario, rather than Toronto, and growing wild rather than in a garden. But it certainly could be grown in Toronto gardens...
