Unknown conifer like plant
I live in zone5 and as I walking around by my school I stumbled upon some plant I've never seen before. There were groups of them and they were in like clay/rock soil. In the small area that they grow in there's no grass and just one of these plants every foot or so.
Okay so, they look like little pine trees. Like nothing i've ever seen before.
-The tallest ones at the site are about a foot tall.
-The tall ones have black stems.
-They have sharp green needles.
-The needles are in rows around the stem.
-About 8 needles on each row.
-There's a row of needles every inch or so up the stem.
-The needles are about 2-4in long.
If anyone can tell me what these very cool looking plants are called i would great appreciate it.
