Tillandsia, also known as Air Plants, are the most amazing plants!
They require virtually no maintenance!!! No soil, no sunshine, just air and fluorescent/artificial lighting. That means they can just chill inside and thrive. =) And what about water?? Every couple of days just dump in a bucket, hold it under the tap, spray it with a garden hose,whatever is the most convenient way you can think of to get it wet. Then, PRESTO, you have the coolest looking, everlasting plant around!
