Thanks for all the enthusiasm about the "plot of land" my landlord offered. I wish I was as enthusiastic as you. I may have oversold it in my last post.
It's about a 1' by 6'' piece of land shoved between two multi-story houses and a garage. I've been watching it the past few days at different times of day and the best sun situation is around noon when it gets the reflection off the neighboring house, which is technically just a reflection off the window of our house.
It's also interesting because further toward the street on this strip of land there's lots of hostas that seem to do pretty well, but they have quite a bit more sunshine.
Here's a photo. I didn't have time to take one, so this is from Google Earth. It must be from before we moved in, but there's plants on the deck, so the tenants before us must have gardened too!

Do you see that tiny, very faint red circle I drew on the photo? Kind of in the dead center of the photo? Yeah, that's the "plot of land" he was so kind to offer.
And this gives you a better idea of how big our deck is. Ok, so deck might be stretching it. It's a glorified balcony. But we plan on filling it to the brim. :)
I'm hoping to take some more photos soon. It's been rather cool and rainy here. Not great for gardening and not great for working on my final exam - the rain just makes me sleepy.
Hope the weather is better for you all!
