I'm sorry that I only now just saw this post. Please let me know if this is the same flower you posted about? I posted it last year as an unknown cranesbill that grows as a weed in my garden. G. ocellatum was suggested as one possibility. It's a small flower on a rangey plant that grows as a perennial, or at least a biennial, in my area.
Yes,that's it's correct name...you probably have the one called Stinking Robert/Bob. Can't think of it's botanical name at the moment. Just up,not enough coffee to kick start the brain yet.Small flower,pale pink flowers,dissected foliage that turn burgundy in the fall?
Fall arrives fairly late in my area, but I'll keep my eyes out and try to remember to report about the color they change to. I seem to recall that they do turn deep red.
The plant flowers heaviest in late spring and then sporadically throughout the summer and early fall. The most outstanding features of the flowers is the almost black centers and the bright green of the sepals (?) that usually show between the petals. It seeds itself readily.
The latin name is Geranium robertianum. Herb Robert is another common name. It is considered to be an invasive, or at least a serious pest. I think it is adorable, but only because I saw it in someone else's garden!
