I grew this JBP from seed beginning about 12 years ago. It has been in the ground most of that time and has grown a beautiful nebari. I have planned on formal upright styling. However, there are several challenges with the tree, now that it is out of the ground and beginning its life in a pot. Here are the defects I see (feel free to see others!):
There are plenty of branches to work with low and high, but there is a large straight 12 inch section of the tree with no side branches and no movement in the trunk.
The buttress from nebari to the trunk has excellent taper, but the rest of the trunk shows little taper.
Some of the side branches are out of balance-- too large and too straight compared to the trunk.
Needles are really pale.
