- Common Name(s):
- Eastern white pine
- Native Plants, Trees
Pinus strobus commonly called the Eastern white pine typically grows 50-80' in cultivation, but will grow to 100' tall in the wild, with records existing to over 200'. Those wishing to have this tree in the landscape, can control it's size and shape through pruning, to the extent that white pine may be sheared and grown as a hedge. It is easy to transplant due to the wide spreading root system. Strong winds may damage this tree. One downside is that t tends to die out in zones 7b and 8 due to stress.
The bark is green with some lighter patches in young trees. As the tree ages, the bark turns reddish brown with prominent finely-scaly, rounded, long ridges and darker furrows.
An important timber tree (perhaps more so in the 18th and 19th centuries than now) which was and is valued for its lightweight, straight-grained wood (orange heartwood and white sapwood).
Regions: Mountain, Piedmont
Seasons of Interest:
Bloom: Spring Fruit/Seed/Nut:
Wildlife Value: This tree is moderately resistant to damage from deer. Its white pine seeds are favored by black bears, rabbits, red squirrels and many birds. The bark is eaten by mammals such as beavers, porcupines, rabbits and mice.
Insects, Diseases, or Other Plant Problems: In cool summer locations, white pine can grow quite well. It is, however, susceptible to a large number of insect and disease problems. Blights and rusts are the main diseases, with its most dangerous enemy being white pine blister rust which is a bark disease that is usually fatal. Species of Ribes (e.g., currants and gooseberries) are the alternate host for white pine blister rust and should not be planted in areas where white pines are under attack. White pine blister rust is not currently a problem in Missouri. Additional disease problems of significance include canker. Insect problems include white pine weevil, bark beetles, white pine shoot borer, Zimmerman moth larvae, pine sawfly, scale and aphids. Spider mites are occasional visitors in some areas.
- 50-80 ft.
- In spring, the Eastern White Pine produces cylindrical, yellow, male flowers and light green, female flowers that mature in clusters. Cylindrical, brown cones on the Eastern White Pine ( 4-8" long) are usually not produced until the tree reaches 5-10 years old. The cones have white lines on the lower side.
- The Eastern White Pine grows well in average, medium moisture, well-drained soil in full sun. It prefers full sun, fertile soils and cool, humid climates and is tolerant of a wide range of soil conditions. However, it is intolerant of many air pollutants such as sulfur dioxide and ozone.
- Medium to fine
- Pyramidal when young; horizontal and ascending spreading branches with age
- 20-40 ft.
- Growth Rate:
- The Bluish-green needles of the Eastern White Pine (to 5" long) are soft to the touch and appear in bundles of five. The needle clusters are deciduous.
