I cannot really tell what type of trees those are - perhaps someone else can?
Once I brought the outdoors in, I was much happier with apartment life. The management wouldn't allow plants outside on the stoop so indoor gardening was my only choice Being surrounded by concrete and busy streets did not help, either. But at least I could sit at my table and eat dinner under that little walnut start.
I see that you have a beautiful balcony. What a great place to grow your plants!
I really understand what you mean by having your own peaceful place. That makes all the difference in the world.
