I have been buying Hostas from them for the past three or four years and have always been pleased. According to their newsletter and the site these are all grade one roses. Below is a link showing the roses actually being packed and explaining the sizing on tree roses.

I just wish I had some more sunny spots in my garden. I would love to try the Cinco De Mayo and Hot Cocoa roses.
