Tillandsia 'Curly Slim' is a fantastic hybrid that is very popular amongst collectors. It takes after both its parents equaly having the curly leaves and swollen base of streptophylla and the slim shape and viviperous (pup/plant producing) flower stem of Tillandsia intermedia.
This plant can in time get very large and make great twisted, curly specimens. It likes high light levels and regular misting with good air-movement.
Here is one large plant as seen in the image.
