This Ponderosa Pine tree was field collected, with permission, (yamadori) by Bonsai Society member Larry Jackel.  In 2004 it was a demonstration tree for the Bonsai Society of Greater Cincinnati and was won in a raffle by Society member Bill Katz who subsequently donated it to the Krohn Conservatory.

Pinus ponderosa, commonly known as the ponderosa pine, bull pine, blackjack pine, western yellow-pine, or filipinus pine is a very large pine tree species of variable habitat native to mountainous regions of western North America. It is the most widely distributed pine species in North America. 

It was first documented in modern science in 1826 in eastern Washington near present-day Spokane (of which it is the official city tree). It was adopted as the official state tree of Montana in 1949.
