What can I plant in deep shade?

I have a spot in my apartment building's courtyard where I buried our beloved family dog. I'd love to plant flowers or something over her final resting spot. The problem is that it's in deep shade. Got any recommendations for plants that grow well in deep shade?


We planted a vertical pumpkin patch in our tiny urban backyard

With urban living comes many advantages. Jules and I both walk or ride our bikes to work, we are a few minutes walk from a zoo, there countless numbers of cafes, restaurants, bars, playgrounds, etc. within walking distance. But there are also some disadvantages. Real-estate is a valuable commodity where we live and there aren't many lots that would accommodate the size garden we wish we could have so we have to get creative.
