Can you see it...in the back of the container is the bright green sweet potato vine I've been nursing along, but in the front is a ball moss, tillandsia recurvata.
Ken's mom used to call this a resurrection plant, because it would look greybrown and totally dead, and then when it gets wet, it greens right back up! A miracle! The oak trees around our campsite were thick with them.
This is an epiphyte - not a parasite. (That means it lives on the tree but doesn't harm it or take anything from it, besides a home).
I am a good Girl Scout, so I know the rule about "take nothing but pictures...leave nothing but footprints." I waited until we got OUT of the State Park to pick this one up off the ground. I have it in my St. Francis garden...eager to see how it does here. We don't have the same humidity that they do in Austin, but WE have irrigation. :)
