About plant names...

Pitch pine is native to eastern North America.

Identification: These trees are often relatively small and oddly shaped, about 40-60' (12-18 m), but they can reach 100' (30 m). Bark is dark and scaly when the plant is young, becoming scaly, peelable plates that are light brown or red brown in mature trees. Needles are 2½-5" (6.3-12 cm) long, in groups of 3, yellow-green or green, twisted. Tufts of needles may occur on the trunk, but I have never seen anything like the heavily needled branches of the tree in four of the photos at right.

For further information, see the Pinus comparison tables.
