Krohn Conservatory Bonsai #35 - Japanese Black Pine

Scientific Name:

  • Pinus thunbergii


  • Japanese Black Pine

This Japanese Black Pine was locally field grown (yamadori).  The tree was donated by Bonsai Society member Dave Billings in 2010. 

It is an informal upright style. The pot is rectangular, unglazed, brown in color and is 6 inches deep.

Pinus thunbergii also called black pine and Japanese black pine, is a pine tree native to coastal areas of Japan and South Korea.

Because of its resistance to pollution and salt, it is a popular horticultural tree. In Japan it is widely used as a garden tree both trained as niwaki and untrained growing as an overstory tree. The trunks and branches are trained from a young age to be elegant and interesting to view.  It is one of the classic bonsai subjects, requiring great patience over many years to train properly.
