In the meantime, I am seeking out palms growing nearby for ideas on what will do well. So far, I am up to two (2) species: Chamaerops humilis and Trachycarpus fortunei. I have found flowering specimens of both in the area, which I take as a good sign.
Today I was at Seaside, Oregon (46oN latitude) and found small palms planted out front of a sea-side hotel that fronts right on the beach. On this "hot" July afternoon, air temp was about 15oC; water about the same. Steady winds NW.
Fronds were wind-tattered but otherwise fine; one Chammie was in bloom.
Palms were small--I would have figured an expensive hotel would have paid for big trunked palms.
