hi we have palm trees growing in gardens everywhere they are a grown in england, hardy
the are best in southwest devon and cornwall thats where i bought mine from, got a red one as well, and a fan palm. they are battered by the winds here. i live by the sea
i grow mine in the back garden where it sheltered as wind gets at them. we where in scotland the other year seen them growing there, tough plants they tolerate -10c i know we got to that temp 5 years ago
