So it's back to trying to figure out what these trees are if they're not cherries.
Two years ago when I first saw this house, I took pictures of some trees in the yard. Not knowing what the fruit was, I held off on tasting it.
Here's what the fruit looks like on the outside and the inside. They largest are about 1 cm diameter (yes, I know that's very small for cherries. I just thought my soil was inhospitable. Yup, that's me, ignoring facts.)
