This is a tree a pal gave to me. He bought it as prebonsai and put in the ground for a few years. When he dug it up to pot it he discovered, to his dismay the trunk was completely hollow. It was chopped and put back into ground to be an ornamental in the garden. It only put out very leggy shoots and he thought it would take too long to turn into anything. In the spring of 2017 I took it off his hands and sorted through all leggy growth and kept 3. The first two growing seasons I thought the hollowed trunk was the feature to present as a front, but this year I've changed to the opposite side. Eventually it will go into a round pot. The flower chains are only beginning to extend.
