Pinus jeffreyi Balf.
Pinaceae (Pine Family)
Synonym(s): Pinus ponderosa ssp. jeffreyi
USDA Symbol: PIJE
Jeffery pine has blue-green, twisted needles, 7-9 in. long. Grows from 40-90 ft. with a pyramidal, open crown. Old trees are devoid of branches for more than 1/2 of their height. Cinnamon-brown to yellow-orange, flaky bark. Cones are 6-9 in. long. Large tree with straight axis and open, conical crown of spreading branches and with large cones. Both bark and twigs give off odor of lemon or vanilla when crushed.
The odor of crushed twigs defies exact description. The scent has been likened not only to lemons and vanilla, but also to violets, pineapples, and apples. This species was named for its discoverer, John Jeffrey, the 19th century Scottish botanical explorer who collected seeds and plants in Oregon and California for introduction into Scotland.
