Hey everyone,

Just curious who is growing london plane tree in zone 4 or zone 5. The city that I grew up in planted 3 of them as a trial and all died in a zone 5b winter. I tried one many years ago and it lost the top half and died the next winter in a zone 5 winter. Am I missing something here? I have seen many sites saying it is zone 4 or zone 5 the worst but it couldn't survive a low of -25?
