You need to contact Robin Middleton(Robin's Salvias) or Rich may know also.
I had heard she closed the nursery but don't know that for a fact.

Christine Yeo's nursery is indeed closed....she is a multi-grandmother! I think she still sells her booklets, you can email her at pleasantview@hotmail.co.uk. She can be slow to respond to emails, but you should also find the booklets on Amazon. Although rather out of date, these booklets are invaluable. And if ever you are in the UK...beg and plead to visit her garden, which is now closed to the public.....it is outstanding.

Thanks very much for the information!
