Tillandsias, also called air plants, are not perfect long-term terrarium plants. They prefer to be out in circulating air. That said, these tillandsias lasted a good long time in these glass jars and I loved the way they looked.
This display was an easy and inexpensive way to display these exotic look plants. Each glass tube cost about $3.00 in the candle department of a big box store, and the small bud vases cost $4.00 for all three. Each tillandsia cost $1.50 at a plant fair. The best part was that it took about 10 minutes to put the whole thing together.
Be careful, when cleaning terrariums, to use a mild cleanser. If you use a glass cleaner, make sure to wash off your terrarium and really let it air out before you put plants in it. The fumes from glass cleaner or ammonia can make your plants really unhappy.
