Does anybody know the cold hardiness of a Chinese Windmill Palm? I heard they were very cold hardy, so I took mine and placed it outside. I live in massachusetts and my windmill palm is a SEEDLING with 2-3 leaves, well I put it outside and for a few weeks it was freezing around here, 30s and 40s. at night it got WELL below freezing EVERY night. One day it was only 3 degrees all day long. I looked at it and the whole thing was frozen outside in its pot. I took it back in a few days ago and it unthawed and there is NOTHING wrong with it. no leaves are gone, no browning or yellow and it looks fine! is this strange or is that just how cold hardy it is? i thought for sure it would die!
