A very common weed in my neighborhood; here horning in on the space set aside for a botanical garden. I'd guessed it was some sort of mint; several members recognized it at once.

A very common weed in my area. I believe it's the non-native 'cut-leaved geranium' ; certainly it's a real pest locally.
