Every once in a while, we think of moving back up to the Portland area, or somewhere in the Northwest. I’ll greatly miss the palm trees of Southern California, but part of me is interested in seeing what I could get to grow, or how lush and tropical of a landscape I could create, given the colder climate. Of course I envision a yard that is more related to the climate, but I would love to have a patio or courtyard that stays green year-round and has the tropical feel that we have here in San Diego.
This post are some of my notes palms that may be possible to grow in Portland and the Northwest. There are of course palms that grow just fine in the Northwest. For our summer visit, I was impressed how large some of the specimens have gotten over the years. I’ll of course plant some of those, but I am interested in things that aren’t as common.
Bolivian Mountain Coconut
These are supposeadly cold hardy down to 16 degrees, and they look fantastic — exactly the frond type I love. I don’t hear too much about them, but perhaps worth digging into. I guess the following page says that they don’t like damp cold…so they probably won’t do well in the Northwest (although if I had that vacation home in southern Oregon where it’s a bit dryer…). I don’t know, maybe super-well-draining soil?
Many of these probably don’t work in reality, but maybe possibilities for palms in Portland (8b):
Butia X Syagrus
Chamaedorea costaricana (Costa Rica Bamboo Palm)
