Staggering contrast - Sunny and Shade

I have a north facing patio, hardly any sun in one corner and other corner is sun all day. Have big gap between two semi detached houses. So in one corner are shade loving plants, the other has potatoes and tomatoes at the moment. The contrast is amazing. I just took the picture, no sunlight turn 180 degree, full sunlight. Thanks to @Fairygirl for educating me about right plants for right sunlight conditions.
