In a Nutshell:

* Jeffrey pine (Pinus jeffreyi) also known as Jeffrey's pine, yellow pine and black pine, is a North American pine tree. It is mainly found in California, but also in the westernmost part of Nevada, southwestern Oregon, and northern Baja California.

* It is named in honor of its botanist documenter John Jeffrey.

* Jeffrey pine is tolerant of serpentine soils and is often dominant in these conditions, even on dry sites at fairly low altitudes. On other soils, it only becomes dominant at higher altitudes where the usually faster-growing ponderosa pine (Pinus ponderosa) does not thrive.

* Jeffrey pine is more stress tolerant than the closely related Ponderosa pine (Pinus ponderosa).

* The Jeffrey pine is closely related to the ponderosa pine and is similar in appearance. One way to distinguish between them is by their cones. Each has barbs at the end of the scales. The sharp Jeffrey pine cone scale barbs point inward, so the cone feels smooth to the palm of one's hand when rubbed down the cone. Ponderosa pine cone scale barbs point outward, so feel sharp and prickly to the palm of one's hands. This gives rise to the memory device for distinguishing between them - "gentle Jeffrey and prickly ponderosa".

* Jeffrey pine has ornamental value and can be found in parks and gardens throughout the temperate world. It has gained the Royal Horticultural Society's Award of Garden Merit. more...

* The seed can be eaten raw or cooked. It is large and oil-rich with a resinous flavor, and is about 10 - 12mm long. The crystallised sap has been gathered and eaten like candy. more...
