Cardamine hirsuta (bittercress)?
You beat me to it, Eva! Bittercress, for sure. 🙂
Go, Eva! You are correct about this being a bittercress. Specifically it is Cardamine hirsuta — also known as hairy bittercress. It’s one of those late winter/early spring edible plants. And . . . lots of gardeners dislike this plant because when the seed pods dry, they FLING their seeds everywhere. You don’t even have to touch the pod. Just stand nearby and listen carefully for the mini-explosions (especially when there’s a breeze).
