Why It Is Popular in Bonsai
The Miyajima variety is prized because it:
Produces fine, proportionate foliage suited to small trees
Develops ramification (fine branching) easily
Maintains balanced growth compared to many white pines
Because of these traits, it is commonly used for refined bonsai styles such as:
Formal Upright (Chokkan)
Informal Upright (Moyogi)
Slanting (Shakan)
Cultivation Notes
Growers often graft Miyajima white pine onto the rootstock of Pinus thunbergii.
This improves:
