Hi all! I have been spending the last couple days weeding an existing mulch bed containing shrubs, and I keep running across this weed (or plant) growing throughout the mulch. I have never seen this weed anywhere on my property other than growing in the mulch. The plant almost appears fern-like, but I don't know. Just wondering what plant this is? I've been looking around online, but haven't had any luck. I am located in south-eastern Wisconsin.
