Oldfield Pine Pinus taeda

Description

Loblolly Pine is an evergreen gymnosperm tree that may grow 60 to 90 feet tall. It is loosely pyramidal in youth and develops a dense oval crown at maturity as it loses its lower branches. The straight trunk can grow 2-3 feet thick. The tree has 5- to 8-inch slender needles in clusters of 3, rarely 2 or 4. As the tree ages, the bark thickens forming irregular, flaky plates that reveal a dark chocolate color when removed. In spring, red to yellow, male flowers and yellow to purple, female flowers mature in clusters.  

The Loblolly Pine will grow in medium to wet soils in full sun and prefers moist, acidic soils with poor drainage but will tolerate alkaline soils. It performs best in climates with hot and humid summers and mild winters. It sometimes grows in pure stands and commonly spreads into old fields by self-seeding. It has the most rapid growth rate of all pines. 

This is an important timber tree whose wood is used for pulp, plywood, and general construction.  Its wood value and rapid growth lend its use towards forest management.

Books commonly cite needles occasionally in twos, although this has never been seen at NC State. This plant is confused with slash pine with needles in threes and twos, and literature data could possibly come from a misidentification in the past. Loblolly has twigs with tufts of needles at the apex. If one holds a Loblolly cone in their hand, grasps tightly and squeezes, the recurved spine of Loblolly drives into the skin. This is a common tree in plantations grown for paper pulp. It is often seen in subdivisions with homes built around these pines. This tree is good for fast screening when it is young and is easily transplanted from containers. 

Fire Risk: This plant has a high flammability rating and should not be planted within the defensible space of your home. Select plants with a low flammability rating for the sites nearest your home. 

Insects, Diseases, or Other Plant Problems:  Southern pine beetle and pine engraver beetle. Fusiform rust and rots may occur. 

Quick ID Hints:

  • Pine tree with tall, straight trunk
  • Needles are medium length and in threes
  • Twig apices are powder-puffed with fascicles, bare below
  • Cones are persisting, sharp-pointed, recurved umbel
