Plant Information

Ponderosa Pine is a massive tree highly recognizable with its five-inch long needles and bristly brown cones, sloughing puzzle bark, either standing alone or mixed with other conifers, mostly east of the Cascades; this is the Yellow pine that can grow up to two hundred feet with a maximum girth of fifteen to twenty feet! But there is also a strain of Pinus ponderosa that is native to the Willamette Valley, a little smaller in stature and more adaptable to our wetter weather. ‘Mary Ann Heacock’ is a dwarf pine with needles half the length of species; growth rate: 2-4”/year

Native Range: From low elevation to highest, coast to far east of the Cascades, depending on species

Characteristics: Evergreen, needle-like leaves bundled in twos, threes or fives. Slow to fast growing, in the wild some species can reach up to 200’ in height. All produce cones.

Prefers full sun and good drainage. Many are tolerant of poor soils. Some make excellent container/bonsai choices.

Pests/Diseases: Pines are susceptible to a variety of fungus and insect pests, though most are not severe problems in home gardens. The exceptions are white pine blister-rusts (five-needled species) and pine-shoot moth (especially two-needled species).

Pines are also sometimes compromised in general health and vigor due to urban pollution and situations of poor drainage.
