For access issues, check out square foot gardening! In my central ohio yard, the bees really are crazy for beebalm (monarda) which is a native & comes in many colors. The also love agastache. These are both full sun. Hummingbirds have been attracted to honeysuckles (not the invasive kind) and trumpetvines (warning, do not plant this unless you want to cover a large and very sturdy structure, and battle its desire to take over the world), also salvias. You must already have things that attract and feed them, though, if they were nesting there. There is a hummingbird forum too; I'm sure they have more info. I sure do wish that I had so much land! I would be planting more fruit trees/shrubs, and one of everything else!

Well, I was going to suggest the ubiquitous fiddle leaf fern, but looks like you have a cat, and they are toxic to cats. You might Google plants that are non-toxic to cats and see if anything grabs your interest. I think some palms may be ok with cats (and they can grow fairly large), or you might look for a contemporary plant stand and just sit a smaller plant on it -- maybe a giant tropical bromeliad or something along those lines. That said, if your cat is prone to pester plants, it's probably not a good idea to include one in your décor. (Definitely don't put a fake plant in this pretty space.)

Here's a few additional pics of the space to give you a better feel for it as a whole!

You could make your room a reading retreat by adding a console (with tv above) and store books, magazines, and photo albums, etc. Try pulling your rug out as well Suggest replacing the small table between chairs with something larger to make that area feel more substantial; but more importantly, for the addition of a good reading lamp, book, coffee cup, etc. Add pillow and a throw and for more comfort, you could move the chairs back a bit as there seems to be room and add ottomans.
