Thanks for the compliment, I used the dried out frog moss you find at petsmart. I think the company is T-Rex that packages it. So far mine has stayed green for about a month, but I soak it down 2x a day. It's just pushed in a crevice between the wood and background. No adhesive. I hope it will grow there. The mass on the floor will most likely get covered with leaf litter at some point. They say that it's hit or miss. So far so good!
