Phlox paniculata 'Nesperis'

Dear Mr C H Garnons-Williams,   
Thank you for your enquiry to the Royal Horticultural Society's Members' Advisory Service. 
On investigation, I have concluded that the phlox labelled as 'Nesperis' in the garden is in fact: Phlox x arendsii 'Hesperis' . 
A search on the internet will generate a great deal of information on this cultivar.
I hope this information is helpful.
Yours sincerely,   

Tony Dickerson
Horticultural Advisor
