Last year I saw Hirt's at eBay had a collection of several different spider plants that were not potted. It was around late July-August. I wish I could remember how many different types they offered. I passed on those and bought a nice curly one and a wide leafed green one. They had a reverse variegated one can Ocean, I believe. I did pass on that one. Hirt's is also now selling on Amazon.
The curly one I purchased is now doing better with more light thanks to pupleinopp/Tiffany and was repotted earlier tonight after following Lin's advice to check the root system. The roots were packed like people in coach airplane flights, or, uh, okay - maybe sardines!
