A window, a forest

We tried to start a lot of seeds this spring, notably trees and climbers. Some didn't take at all, but the things that did... oh my. This is our bedroom window at present. All of these things will have to be transported to our land, together with all the plants that have stayed outdoors over winter, and all the seeds still stratifying in the fridge, and everything else we'll need... Rental trailer!

Sorry for the bad picture quality, by the way. My camera sucks. Anyone have any guesses as to what these things are?

Just guesses,  but I possibly see chestnut and walnut.

Chestnut is correct, but no walnuts. They're still in the fridge.
