That looks like a good shady place to plop in some flowering plants and small shrubs. Spring is the time of year when gardeners lift and divide their Iris and Daffodil bulbs, Hosta, Forsythia, Tulips, Grasses, Liriope, Ferns, and other clumping plants. These types of plants usually get divided out every three years.
I have been gardening many years on a shoestring budget. Most of my many plants came from other people's gardens. Folks are always willing to share if they know other gardeners are in need. Sometimes just talking with others can bring about a situation where they will ask you to come and dig out whole gardens for their ailing mother who is no longer able to care for them and wants them gone, but also wants them to go to someone who will love and care for them. This happened to me once. I dug out the most beautiful selection of Lily's that you have ever seen and many more specimens than I ever could have imagined.
If you are still employed you could post an index card on the bulletin board and post one in every place you have access to, i.e., church, daycare, grocery, etc.
Please do not think that gardeners will take offense at asking for them to share, because every garden lover that I've ever known loves to share their bounty, seeds, knowledge, and wisdom. Take the plants and plant them, sow the seeds in pots, grow your garden, grow your friends, grow your neighbors, and grow your property for the added beauty will be prominent in 3 years when you decide to sell.
Good luck and good gardening.
Here are some annuals that will live comfortably in the shade and self sow, or at least cast plenty enough seed for the next growing season if left be. Forget Me Nots or Myosotis, Nigella or Love In A Mist, and Hardy Begonia's. I would plant the Nigella in that dappled sunlight area.
