What is this plant? It's growing sparsely (I've flagged around 30-40 of them over ~5 acres) throughout my back yard in northern Ohio.
It is very sharp and has a pretty deep/vertical root system. It's mostly brown right now, but I did find a few that are starting to turn green now (early April).
Size is anywhere from around 2 inch diameter up to this one, which is more like 6-7 inch diameter and seems to be growing fairly horizontally, though I would have been mowing them down all of last year, since I didn't notice them until this year.
When I cut off a piece, it did smell like what I imagine as "pine", but I don't have a super discerning nose.
Tried looking it up via Google, but no luck so far.
Is it a weed? A bush? A tree?
