Hi Jim,
Yes indeed, it is a marvel, I know, for England.
We do have palm trees growing, not great big ones, but nevertheless, palm trees.We have them in Torquay,
and some of my neighbours, have them in their gardens!!
They grow mainly, down here in the South-West,
mainly in Devon and Cornwall,which sometimes,
can be many more degrees warmer, throughout the year,
then it is up country!!
Best Wishes,
Keith
