I love this stuff! What is it? Does anyone know? I grows on big sandstone boulders. When it's wet and cool like the current weather, it turns a rich emerald green like in the photo. When it's hot and dry, it gets a crispier feel and is gray instead of green. It's like thick, thick carpet. In spite of this being in a spot on the property we call rattlesnake hill where poison ivy, briars, thorny and sting producing plants are plentiful, it always makes me want to shed my shoes and go barefooted. Can some of it be scraped off, moved and enticed to grow to grow?
