Cinda: I'm not sure about the Dietes as a container plant but I'd think with a lot of sun it would do okay. Here in Florida they are landscape perennials and they spread to form huge clumps. I recently moved and I wish I had dug up a division of that one! Next Spring I will have to check out some of the local garden centers for another one, they are usually in abundance at nurseries and garden centers in the spring time.
