Northwest Conifers

Jeffrey Pine – Pinus jeffreyi Speaker

Jeffrey Pine

Jeffrey Pine at Hoyt Arboretum


USGS Distribution Map

Needles: Bundles of 3, 6-10" long

Cones: 5-10" long, egg shaped

Bark: Brown puzzle pieces

Where:  Mountains of southwest Oregon


Needles: Like Ponderosa Pine, it has 3 needles per bundle. Jeffrey Pine needles typically grow farther along the twig, while Ponderosa Pine needles are bunched at the end.. 

Cones: The cones are 6 to 10 inches long and have a sharp prickle on each scale. Although Jeffrey cones are often described as less prickley than ponderosa cones, the difference is a subtle one. Cone size is the best way to distinguish Jeffrey Pine from Ponderosa Pine, which has smaller 3 to 6 inch cones. The prickles do tend to point out more on Ponderosa cones, but this doesn't mean you won't feel any pain when you pick up a Jeffrey cone. Also, the Jeffrey prickles are long and narrow compared to those of Ponderosa Pine.

Bark: The bark looks similar to Ponderosa Pine with flat plates shaped like the pieces of a jigsaw puzzle. But Jeffrey Pine bark is brown. The bark is variously described as smelling like vanilla, lemon, or pineapple.

Where it grows: Southwest Oregon and throughout the Sierra Nevada of California up to the timberline. 

Uses: Similar to Ponderosa Pine.

Names: Named after Scottish botanist John Jeffrey. Other common names: Western Yellow Pine, Bull Pine.
