I’ve got some shady spots in the landscape, and I’m always looking to convert more of the front yard over to edibles. This sounds like a good fit that will give a few bonus berries and slowly spread to fill out these otherwise unproductive areas.
I’ve got wintergreen. It’s in the back of my yard, growing under and between my remaining blueberries.
It flowers well, but I rarely see the fruit, it tends to be under the foliage. I can recall enjoying chewing on the leaves more than the fruit, not that they are bad just because the leaves are always there. I agree that the fruit is mealy. It stays evergreen (well reddish purple- leaves) year round.
