The most common pine in North America, the ponderosa Pine grows with yellowish-brown to cinnamon-red bark in flaky plates. It prefers deep moist well-drained soil but will grow in a wide range of conditions.
There are 3 distinct regional varieties of this native tree that often grow in pure stands. In the Pacific coast region, the variety Ponderosa Pine or Pacific Ponderosa Pine has long needles, 3 in a bundle and large cones. Rocky Mountain Ponderosa Pine or Interior Ponderosa Pine has short needles, 2 in a bundle and small cones. In southwest Arizona, you can find Arizona Pine or Arizona Ponderosa Pine. That variety has 5 slender needles in a bundle.
When broken, the trunk, twigs, and needles emit a pleasant aroma.
Its habit is narrow pyramidal in youth, irregular crown with age. It has numerous short branches and drops its lower branches. Old trees have no branches for more than 1/2 of their height.
There is some susceptibility to root rot, blister rusts and needle blight.
