Dicksonia antartica though rated zones 9 and 10 can winter over in warmer zone 8 portions of the Pacific Northwest. The trunk needs protection. Having said that mine is in a pot and goes into the greenhouse in winter. I can see protecting it while small but as a tree I don't think I could. I plant the pot in the ground in the spring and dig the pot up in late fall. Grows fairly fast. I am thinking of trying another one outside next to the house just to see if it will work with no extra protection. ###################################### Debra Teachout-Teashon Pacific Northwest Gardening Fuchsias Grow Great in the Pacific Northwest! http://www.suite101.com/topics/page.cfm/416 #######################################
