Growth Characteristics of Pinus Strobus
- Assuming a pyramidal shape when young, white pine eventually loses this defined, symmetrical shape. As it ages it becomes irregularly shaped, even "picturesque" in its unusual form, which can include a flat-topped or scalloped crown. Its lateral branches make a dense canopy, even if irregularly shaped at maturity.
- Pinus strobus grows 50 to 80 feet tall in cultivation, but can reach 100 feet or more in the wild.
- White pine's thin, flexible needles grow about 4 inches long and are light green with a pronounced bluish cast. The needles are attached in groups of five on each fasicle. The needles do not change color in autumn and persist on the tree for at least two years.
- Pine cones on Pinus strobus are light brown and 6 to 8 inches long. They are produced in abundance by the tree beginning at about 10 years of age. As the tree matures, it produces the majority of its cones on the upper third of its branches.
- New-growth stems are silvery-gray, while mature bark is gray to gray-green. The bark is smooth when the tree is young, becoming furrowed or scaly when mature.
