Which City Would Grow More Subtropical Pittsburgh or Juneau?

You could possibly grow them in the Ketchikan area, at the southernmost regions of the SE Alaska panhandle. Again, relatively low summer temps could be a problem.

Just because a plant is hardy to say -5F and your winter temp never gets that low doesn't mean the plant will grow. That's my experience with bamboo in Juneau. Besides some of the Fargesia species, forget it. They just won't size up during the short, cool summer and eventually will die during winter.

One thing I notice about hardy palms is they do better in more wet climates.

I notice dry and windy weather really damages palms no matter what the temp is.

I think it’s true, they planted sabal minor in St. Louis it did well, it got windy and dry sometimes but not as bad as when they some in Denver which was way drier. Not all died there but surely more than St. Louis.

Juneau is 7a but since it lacks summer heat it is harder to grow them. Also I noticed Juneau is in a cool temperate ecoregion while Pittsburgh warm temperate one, obviously shows which one lacks heat.
