Kim Fisher has been involved in floral design, décor styling, and creative consulting since 2000, and if you want an air-plant hanging on your wall, she's the one to ask. Fisher's Etsy store sells half-enclosed 22-inch hanging wall planters that are specially made for succulents and air plants. $212.50 USD gets you one planter and two plants.

Air-plants are typically of the Tillandsia genus and absorb water and nutrients through their leaves; over 700 species exist, and most use their roots to anchor them in place.
These hanging gardens are available on Etsy.
