About plant names...

The Jeffrey pine is a North American native, found in California, Oregon, and Baja California.

Identification: Trees reach 79-128' (24-39 m) in height, and 24-47" (60-120 cm) in diameter, rarely up to 50% larger. Bark is yellow brown to cinnamon-colored, with large scaly plates and deep furrows. The resin has a scent variously described as similar to vanilla, lemon, pineapple, violets, apple, or butterscotch, which distinguishes it from the similar Ponderosa pine's neutral or turpentine-like scent. Needles are in groups of three, bluish-grayish-green in color. They are 4½-9" (12-23 cm) long. Cones are 4½-9" (12-24 cm) in length, dark purple at first, becoming pale brown, with thin woody scales and sharp inward-pointing barbs.
