Bay? It tolerates shade.
Or mint.

Bay is good, and as I mentioned in another post, we do have
a bay in a pot that needs planting out. I'd just be worried
that it would be a bit close to the house for what is
essentially a tree.

Mint is something neither of us are particularly fond of in
our food, so wouldn't be that useful to us.
