Tillandsia stricta “Green” is huge. And it has purple blooms! What more could you want? You could want for nothing more. I assure you.
People ask us how do you take care of airplants? And I tell them to keep them in bright indirect light, a little direct sun is OK but not too much. Mist 2-3 times per week, or dunk in water once per week – I usually run my under a faucet weekly and then shake it off. Always make sure they dry out within about 4 hours of watering them or they might rot. And finally you should add nutrients to the water once per month. We use an organic Liquid Seaweed at low strength.
