Its range is mainly confined to the sandy and gravelly deposits of the Coastal Plains, from southeastern Virginia to eastern Florida, and west to eastern Texas. Longleaf pine essentiallys grow at sea level, usually below 600 feet (183 m), but is also found at elevations of up to 2000 feet (615 m) in the foothilhs of Piedmont. Heartwood Color Brown Red White Yellow Orange Pink Purple Yellow to golden-yellow to orange Reddish brown Pale brown White to cream Pale red to pink Brown Yellow, but may contain blue-black sap stain Red Light yellow, orange, and red Slow-Growth Longleaf pine usually recovered from structural timbers in pre-1900 warehouses and factories, or as sunken logs from river bottoms have a yellow heratwood after cutting, but the color turns to a deep pinkish tan to warm reddish brown within weeks because of high resin content The tree is believed to develop heartwood late in its life (18 years). Sapwood Color White Yellow Brown Red White to yellow Paler than heartwood Whitish to yellowish, orange-white, or pale yellow Well defined Variable width Grain Figure Growth rings (figure) Straight Distinct (figure) Even Clear growth rings (figure) Straight Distinct figure Straight and uneven Contrast between transition from earlywood to latewood is described as striking in its abruptness.
