Plants that grow in full shade?

I need a list of edible plants that grow in full shade.

The summers here can get very hot, I have set aside an area so I can make a 1000 square feet courtyard, and this courtyard will have at least 50 large leaf deciduous trees planted in and around it, I am going to have an Aquaponic system in this courtyard so the constant flow of water can help cool down the shaded courtyard even more.
I am doing all of this so I can have a nice cool place to sleep on those hot summer nights.
I am also going to make other larger courtyards that have plenty of sunlight to grow my food so don’t worry.

I would be a lot easer for me to just put a water fountain in the shaded courtyard but keeping with Permaculture why do it one way when you can do it a different way and also get food out of it.

So far the only plant I have on my list is Japanese wasabi, it thrives in 80% shade.

Mushrooms?
Rhubarb
Asparagus
Chicory
Dandelions

Anything that needs to be forced.

Look for the plants with a high edibility rating then check them for zone hardiness.

I have been planting cabbage under a shade tree. It is partial shade and they do great in the hot summer.

without knowing your location, it can be hard to help.
i personally know that prickly pear cactus and aloe species and ginger species grow very well in the deep shade or better in dappled shade. i also grow many varieties of ornamental bromeliads and even a couple pineapples in the deep shade. any understory plant can probably grow great in your shade, what is local to you?
i heard them thar yanks can grow ginko in the shade.

I have found that schisandra aka magnolia vine grows really well in shade. They will not take hot summers in the sun. I planted two 'eastern prince' vines last fall, one of them already has fruit on it.

Arctic kiwi, Mongolia vine, anything in the blackberry family, strawberry, onion family, fern family, warre bee hive, seakale, seabeet, gooseberry family, autumn olive family, sea berry and supposedly hazelnut.
