I am building an outdoor turtle pen for my gulf coast box turtle and the area I am building the pen in has these plants and I'm not sure what they are or if they're harmful to my turtle.
I agree, it sure looks like Carolina Cranesbill (Geranium carolinianum) but I have no idea if it would be harmful to turtles. It always sprouts up in my lawn this time of year.
