Three photos of the same tree at different times. I think it's probably the same baby too. No identification of the tree is given, but it looks a lot like a Japanese beech
I try to focus on bonsai and stay away from babies and kittens (here on Bark at least), but for some reason I couldn’t pass this one up (it helps that the tree is magnificent). The babies and the photos below were posted by Matthijs Hartjes, a Bonsai Bark first timer.
Japanese maple for sure, but no variety is given
Here's a tree with a lot of potential. Again, no variety is mentioned, but it looks like it might be a Japanese white pine
