The mother of all air plants, the Xerographica are beautiful, easy-maintenance plants for any space. Though a lot of people think air plants don't need any care, they do, and once proper care happens, they thrive!
Air plants do best with lots of bright, indirect light, but will also thrive under flourescent light. Contrary to their name, they don't actually live off air, and need weekly watering. Give them a 30-minute bath or run water over them for several minutes, shaking off excess water and placing them somewhere they can dry in ~4 hours. They also appreciate regular misting!
Small Xerographicas are between 4-5 inches wide.
Large Xerographicas are between 6-8 inches wide.
