I just finished up work on the big Dwell on Design show coordinating the outdoor section and working closely with a lot of plant people (nice people!). I was struck by the amount of air plants (or Tillandsia) that were used throughout the show and as accessories in modern interiors. Could Air Plants be the new Terrariums?
Tillandsia can grow without soil and with little water (though they like humidity and do not like direct sun). You can keep them alive by either misting them or soaking them once a month. I loved seeing a bunch of air plants as accessories in a bowl on a table and, in a more dramatic play, as an ethereal sculpture in the center of the Outdoor Section (see images 3-5). The Tillandsia shower at Dwell on Design was concepted by Shades of Green, a landscape architecture firm in Sausalito.
Because they're so hardy, they could definitely vie for a place in our list of foolproof plants that can almost survive the dark. And if you're looking for a place to buy them, check out the online shop, Rainforest Flora.
Here are some of our other favorite ways to display airplants (and yes, Terrariums are a good option):
