Alex brought these to discuss. The first is an ezo spruce, Picea jezoensis. Alex has wired all main branches and formed a rough sketch. This looks fine and now he has to wire every single little branchlet. This will look great on a flat stone.
the other one is a gingko, Gingko biloba. It is quite small and the pot by Horst Heinzlreiter is great for it. In fall, with the yellow leaves this will be a splendid sight.
