Are you just generally fed up with flowers in your home? Want to break out with a plant that makes your friends go "Huh?"
Low on cash?
Why not grow some air plants!
Step 1: What is an Airplant, and how do I get them?
Air plants do not harm their host, instead using it as support. When attached to trees, they grow root-like tendrils to latch themselves in place, which can be safely broken off if harvesting.
The Genus Tillandsia is the most commonly sold, and the type pictured in this instructable. I suggest starting with one of these.
I bought my air plant at Marfield's, an American garden supply chain, for $4.99. That simple. They can also be purchased online, in greater variety, here.
