Plant Story--the Strawberry Tree, Arbutus unedo

I was a tourist in Portugal and only caught the end of the guide's tale, "...strawberry tree." 

Strawberry tree?! Strawberries don't grow on trees! 

And, that's true, strawberries don't grow on trees, but there is very definitely a tree whose English name is strawberry tree.

strawberry-tree fruit, Arbutus unendo

It is Arbutus unedo, generally called the strawberry tree in English. It is in the heath family, Ericaceae, related to rhododendrons, blueberries, and cranberries, not at all closely related to strawberries, which are Fragaria species in the rose family, Rosaceae.

Plant Story-- A Little Bit about Cranberries, Vaccinium species

Cranberries (usually Vaccinum macrocarpon, heath family, Ericaceae) are a major crop. The tart red berries are usually made into cranberry sauce, served on or with meat, not used as a fresh fruit or even a jam. They are a common and handsome red fruit drink, which is usually sweetened or mixed with juices like apple and grape because a juice that is pure squeezed cranberries is so tart only a few people will drink it. Cranberries are the fruits of small, sometimes viney shrubs that grow in cool boggy places.
