We found some great advice for caring for your new Air Plant (or Tilandsia) at Gardenista.com.
They are so easy and require nothing more than some light and some water on a semi-regular basis. With no roots and no soil to worry about, you can put them in a myriad of different containers or simply leave them sitting on a dish, countertop or window sill.
We have dozens of them in the store, from tiny to large. Easy to add a hit of greenery just about anywhere.
