What Can I Grow in My Dark Spot?

Evening distinguished horticulturists,

I have a spot in my garden, which is the northern side of my house and light is further blocked by a 5.5ft hedge on one side. It does get some direct light, but only in the mornings and evenings. I successfully grew artichokes there two years ago. This year, I tried growing Babbington's Leek there, which is a largely unexplored perennial leek. These didn't grow much and died in August, which may just be their habit as they use the first year to produce bulbs, which they did. Though I don't want to waste a patch on them next year in case there is not sufficient light.

So, my question is: What can I grow in this patch that will be happy with the low light levels. One thing I am keen to grow is spinach.

I've tried various forms of kale / broccoli but the slugs ate them before they could grow to a decent size 

Have you tried Nemaslug? I've heard good things about it, but not used it myself.

In doing some research, I have come across a plant I already have that can grow in full shade:

Very nice specimens are available from:

This is a good tasting berry that is very similar to bilberry. It also has nice flowers, so quite a good one to fill in a few dark patches. The only thing letting it down is the berries have spaces in them.

Hmm; it spreads "vigorously through suckers" - my border is only 4' deep, I don't want it turning up in my lawn 

- or anyone else'  :ohmy:s lawn either! Er - forget that one. I find that brassicas like caulis do better with some shade as they don't bolt quite so quickly.

redcurrants, hazel nuts and american land cress.

Rhubarb mine is placed in a similar spot, shaded most of the day (apart from very early morning)  it grows like a triffid.
