I really should have recorded the names of the plants when I was snapping photos at Meijer Gardens. It's not like it would be difficult or time-consuming. I'll have to remember next time to take a picture of the name plaques next time we visit.
It looks like moss -- sort of. It also kind of looks like juniper needles. It's a rather primitive plant, I would guess.
It's too bad there weren't any botany or biology courses available at Lawrence Tech University.
