It's Arbutus unedo, common name strawberry tree. The fruits are edible, though they don't get rave reviews. I just learned from Arbutus unedo - Wikipedia that they're the basis of the alcoholic drink rakia, which is distilled twice to reduce the amount of methanol.
The species name unedo means "I eat only one" - though they're not quite that bad, actually, I once managed to eat ten at a sitting ツ The red outer skin is rather gritty-textured, and the inside mealy and lacking in flavour, but they're not bitter or astringent or otherwise nasty.
It interests me - esp w reply from person who seems to be in UK that this plant and fruit was featured in UK designer William Morris fabric and wallpaper designs over a century ago (this I think is 1913) - see link below And yet we have Arbutus naturally and uniquely in the Pac NW — are the two related?

Yes, they are both species in the Genus Arbutus. Arbutus unedo is native to Europe, n Africa and w Asia. Arbutus arizonica looks very similar to our Arbutus menziesii. A. menziesii fruit is also edible, but even less desirable. Dry and mealy.
Though I remember seeing a genetic study that showed that the Old World and New World Arbutus species are not each others closest relatives; the Old World Arbutus are more closely related to Arctostaphylos (Manzanitas) than they are to the New World Arbutus. The New World species should really be split off as a new genus, but it hasn't been done yet. Edit: found it - http://online.sfsu.edu/parker/pages/respubs/HilemanEtAl2001.pdf 19 years ago, very odd that nothing has been done about it!
