Any edibles for fairly deep shade at all?

[Fucksandflowers]

The back garden is going to take a while.
I keep coming back to the idea of a 100% edible potager design.

Trouble is, I have a patch with overhanging trees which obviously casts some shade and don't know what, if anything I could plant there.

Currently, I have two gooseberries and a morello cherry tree in this shaded area but I need some sort of ground cover....

There is Ajuga there which is obviously non edible and my (non edible) plan was hellebores and Japanese anemone with it.

I already have a full herb garden in the front so not interested in herbs.

I was planning on putting dwarf raspberries and blackberries in the two sunny borders.
Unless they would produce a decent crop in the shade..?

Is there anything at all edible suitable for shade?

Alpine strawberries are what cover my shady areas. Tedious to pick, but intense strawberry taste. They're best added to other stuff - sprinkled on cereal, mixed with cream and used to sandwich a sponge cake together, for example. If you have any left over, they freeze better than full sized strawberries.
