Bluestone used to offer them, but I don't see them listed now- maybe they haven't updated the site?
Jennifer, I found them at 2 garden centers in Lexington last spring, and between the 2 there was a pretty good selection available. One had 4" pots, the other only had gallon pots- I'll let you know what I find- happy to mail some to you if you'd like. Henfield Brilliant is the variety I got last year.
