Really useful! A friend and I were walking through Worle village this lunchtime, just a couple of miles from Weston super Mare, and in a front garden was a truly lovely example of Magnolia x leobneri, Leonard Messel. We stood some 3-4 metres away from it trying to puzzle out what it was and we guessed it was of Magnolia family but stuck with that. It was about 2 metres high and the same around, and simply gorgeous in full bloom in the afternoon sunshine.
Thank you so much!
