This is an ash sapling that self seeded in the garden 3 or 4 years ago. It was put in a flower pot and then has been largely ignored since then but recently I had a closer look and I actually really like it as potential bonsai material. In fact, next spring I may just give it a root prune and plonk it straight into a bonsai pot.
The trunk has some movement, internodes are pretty short and there’s promising nebari. It’ll be something a bit different but after some surgery, it could be nice as a shohin bonsai tree.
