Wild Geranium, Geranium maculatum, that is!
The five petaled rose-colored flowers are delicate, but after they fall the seed pod is impressive for such a small wildflower. Those long green things are supposed to look like a crane’s bill, and Ms. Flora, our resident plant squirrel, tells us their shape are how we can tell which of the wild geranium’s this is. (Yes, there is more than one species!)
Because the top skinny part is about half the length of the fat part–where the sees are growing–we believe this is the ‘Wild Geranium’. The leaves also confirm this, but all those geranium leaves look alike to squirrels.
