Somewhere warmer (but not too hot). Britain is a wonderful country to garden in. Tresco would be good I think, though I've never been there.
What is your favourite public garden?
I never tire of the greats - even with the crowds, though I try to go midweek always. Sissinghurst, Great Dixter, Hidcote, Beth Chatto's of course. Giverny was a great influence - ordinary plants used to extraordinary effect. The times I have been there it got quieter in the garden over lunchtime - I wonder if that still happens. Beningbrough Hall and Piet Oudolf's Scampston in North Yorkshire, and his Millenium garden at Pensthorpe in Norfolk....It's impossible to choose. I refuse to choose!
