I'm not sure which binatas they offer for $1 each. The forms that I have seen there are D. binata var. dichotoma 'Giant' and D. binata var. multifida. These are both healthy plants, particularly the giant dichotomas.
I can't remember seeing any normal T-form binatas but they probably have them. I'm sure if they were selling any for only $1 each it would be them.
