I believe the post concerning riccia as a carpet is rather misleading. To my knowledge, riccia will not root or otherwise attach to anything, as it has no method of doing so. It will have to be anchored with a monofilament line and pruned regularly. Just my $.02 Scott BTW, what about E. tenellus? I was planning to get some of it for a lawn type plant.
