Imrie also told the BBC, "We think the exhaust from the house's heating system, which comes out nearby, has raised the temperature and helped it grow."
The windmill palm (Trachycarpuspus fortunei) originated on the island of Zhoushan, which is south of Shanghai. Windmill palms thrive in parts of Britain, and they have also been grown in Bulgaria and Switzerland. Windmill palms have been grown in Seattle and Vancouver.
