Our hardiness zone is somewhere between 5 and 6, I gather. We are only about a thousand miles farther north than Seattle, Washington, a mild climate, and about 600 miles farther south from Fairbanks, Alaska, with notoriously extreme weather.

Alaska is large (According to Wiki: the E-W extension is 2,261 mi (3,639 km); the maximum N-S extension is 1,420 mi (2,285 km) and Juneau is in the panhandle. This low in Alaska we don't have 24 hour sunshine (or darkness); our longest day gives us about 6 hours of sunlight. (Note that I didn't say 'sunSHINE. :) Our weather is typically cloudy/wet and cool.)

I've had a couple of tourists assure me that our climate here in Juneau is not all that different from that of London. I like it- our cheeks are always cool, if not crisp. :)
