One cute idea that I used to see sometimes back in Chicago is using cinderblocks turned on their sides as planters. I found an link here from the apartment therapy website on how to make a DIY succulent planter, and thought I'd share their image for inspiration. There's more of a tutorial on the site if you need it, but it seems pretty self-explanatory.
Poetic Home has some really cute ideas on how to repurpose things around your home into planters. I always get a little nervous when people don't allow drainage, no matter how many rocks/pot shards are at the bottom of a pot. But the ideas are so cute and (as long as your plants are small and carefully watered) a great idea for ways to cram plants into every last nook of your home.
And, of course, there's always Crate and Barrel. I've got a few of each of their Hanging Candle Holders and Beaker Wall Vases at home, and they're each great in their own way. My boyfriend keeps his air plant in the candle holder, misting twice a week, and I keep cuttings of pothos or other draping, viney plants in the wall vase. Probably anything that's happy without soil would work, though.
Check out the Flora Grubb website for great ideas on air plant display as well as tons of other fun indoor gardening ideas. Another favorite of mine, the vertical garden, is pictured below. Ms. Grubb is a fantastic source of inspiration, and great floral design happens there, too!
