In Japan there is a concept called ma — the art of negative space, the meaning carried by what is not there, the pause that makes everything around it more than it would have been alone. The Ghost Succulent understands ma in a way that most plants do not. The Pea Green Ghost Succulent is a ceramic wall succulent, 4.3 inches across, one screw, no water. Pea green is the color of something that has just decided to exist. The ghost part is the space around that decision. In Japan that space is not empty. It is the whole point.
