Well, that's surprising and disappointing especially for such an illustrious name nursery. I thought they were still exhibiting at the big shows and winning medals - maybe I'm out of date.
I'd better stop being lazy and get the RHS Plantfinder out and see if there are any other major UK growers who have paeonia displays in season.
Talking about displays in season, Ayletts in Hertfordshire has a peerless display of Dahlias at this time of year. The display field is about two miles from the Ayletts garden centre - see
www.aylettnurseries.co.uk/ for details. Their annual dahlia festival is coming up; 11-20 September. No connection disclaimer, they're just a class grower.
