I don't have one of these. I did once - I guess it must be blooming somewhere now. I ordered a LOT of plants from Ratcliffe the first summer I was growing and at the time their free special was St. Swithins and I got three! The last one they really nicely traded for a Susan Booth, but it was big and not a favourite so I think I sold it or traded it to Ron Rayher. Come to think of it, I think he may have posted a photo recently on OSF.
Anyway, yours is lovely, thanks!
