As urbanites get more and more isolated from the natural world, their desire to maintain some sort of connection has inspired creative new interior design ideas like moss walls to fill their needs. Moss walls are a beautiful and relatively low-maintenance way to bring some beautiful nature into your home.
Though walls like these can be expensive to install, they are easy to maintain – especially if they use lichen instead of moss. As long as you maintain the appropriate indoor humidity and keep them out of the sun, you won’t need to water them. (H/T: Bored Panda)
