Looking for shade tolerant vegetable seed cultivars and suppliers

Assistance is requested finding shade tolerant vegetable cultivars...our garden is south-facing, but 200 foot Douglas Firs inhibit full sun all day long, rather, the beds get shade dappled at different times of the day in sinc with the sun's transit.
Overall our garden does well, but I am searching out varieties of all types of garden veg that are more tolerant of some shade.
Any assistance with this is much appreciated.

 

Thanks for the question. I am very interested in this suject as well.

 

Howdy, tuning in. Much shade, no veggies. Had some trees taken down which may help, but still not sunny. Is there hope?
