I have two pots of Red Bugs, and they've always had this mossy stuff growing on top of the soil, which I think is nice. But the other day when peepin' my plants, I saw these leaves. I tried picking one up to see the underside, but it's like they're attached to the moss. Or maybe the moss is attached to it. I got a chunk off (maybe not a good idea?), and it almost seems like a fabric-y plant. What in the world is this?
