Found these coming up quickly in my yard and not sure what they are. I live in Northeast Ohio. Stem starts out red then turns green.
Looks like it could be peony, at a glance. Depending on how happy it is or isn't you might get some impressive flowers, or just foliage. Red start going green and general shape look correct based on mine. They will generally benefit from some support, especially if they are happy enough to bud and flower. Also, don't go nuts killing harmless (perhaps even helpful) ants on the buds.
