Bristlecone Pine

Pinus aristata (PY-nus a-ris-TAH-tuh)

Family: Pinaceae Unknown Understory (15-40 ft)

One of the oldest trees on earth, this tree is a dwarf, shrubby but picturesque specimen with an irregular (rounded, flattened) spread when young and retains these characteristics as it matures. Its tapering, twisted trunk is up to 3 feet in diameter. Its blue-green needles are aromatic and covered with a resinous fluid. It will grow in a variety of soil types including dry, infertile or rocky. You may want to protect from drying winds. Insect, Diseases, and Other Plant Problems: This tree is susceptible to wind damage. Watch for bark beetles, aphids and needle scale. Diseases include white pine blister rust and dwarf mistletoe.
