In your database, I can verify that all you say about 'Best Wishes seems true, but it is mystifying to me that you neglect to mention that is is one of the only roses to show cream variegation on the leaves.
I bought mine in 2009 from a reputable specialist in Norfolk, UK who said he was unaware of any other such, and that it was possibly unique. It is certainly the rose's most noticeable attribute, yet not vaunted by garden.org. Why?
