Willamette Valley Ponderosa Pine (Pinus ponderosa var. benthamiana) is a beautiful tree with long needles and attractive bark. Like all ponderosas, the bark of this tree has a vanilla-like scent when warmed by the sun–and they love sunny spots! However, the Willamette Valley Ponderosa is the only variety of ponderosa that can also withstand the heavy wet winter soils of our region.
This long-lived tree is very valuable for wildlife. Its needles are the only known food for gelechiid moth (Chionodes retiniella) caterpillars. Many species of birds and small mammals eat the nutritious seeds and use the needles for nesting material; others use cavities and branches for nesting and shelter.
Willammette Valley Ponderosa Pine is one of four different varieties of Ponderosa Pine, each adapted to different climatic conditions and with differing botanical characteristics. When planting in Multnomah County, it is very important to use this variety, as it is the only one that will thrive in our region.
