I am a volunteer at a botanical garden in the midwest and I would like to buy 50 or more Tillandsia ionantha to use in the creation of a living wall. The Tillys would be used as fill in for other epiphytic plant material so I am hoping to use inexpensive, medium sized 2-3 clump plants--nothing fancy. Can anyone direct me to a reliable grower with good prices within the U.S.?

Thanks!
