Loblolly Pine (Pinus taeda)

Loblolly pine is the leading commercial timber species in the southern United States. It is a medium to large tree 90-110 feet in height and 24 to 30 inches in diameter. The bole is long and cylindrical and the crown, though open, is denser than longleaf or slash pines. It can be found on a very wide variety of sites but make its best growth on those soils with deep surface layers having plenty of moisture but poor surface drainage, and fine textured subsoils. On favorable sites growth can be rapid. Loblolly is intolerant of shade, though not as much so as slash and longleaf pines. Loblolly is a major source of lumber and provides a large percentage of the wood pulp used for paper production in the South.

Georgia Giants: This mix of three of the fastest-growing, open-pollinated loblolly pine families in the Southeast are expected to produce 53.5% more volume at age six; excellent rust resistance; good straightness. Recommended for Coastal Plain only. PRS Spec Sheet

Select P3 Loblolly: Selected families from a third cycle piedmont orchard expected to produce more than twice as much volume at age six than unimproved loblolly with superb rust resistance. Recommended for north of the Fall Line. PRS Spec Sheet

Select RR3 Loblolly: Selected families from a third cycle orchard producing 40% more volume at age six; impressive rust resistance; good form characteristics. Recommended for the Lower Piedmont and Coastal Plain. PRS Spec Sheet

3rd Cycle Elite Straight Loblolly: This is a mix of three of the straightest, most fusiform rust resistant seedlings from our 3rd cycle selections. These seedlings, through field progeny testing have proved to grow extremely straight, with very low incidence of rust. They also produce 36% more volume per acre at age six. PRS Spec Sheet

C-3 High Volume: This third cycle Loblolly variety is a small seed orchard mix of a few families that produce 48 percent more volume per acre at age six as compared to local unimproved checklots. It is just under our famous Georgia Giants in volume production, and is suitable for the coastal plain and lower piedmont. PRS Spec Sheet

Slash Pine

Slash Pine (Pinus elliottii)

Slash pine varies from 60-100 feet in height and averages about 2 feet in diameter. In virgin forests the species was found in depressions, around ponds, and on low sites with an abundance of moisture largely because of its relative sensitivity to fire. With the advent of fire control slash pine has invaded drier sites in combination with the more fire resistant longleaf pine. It quickly seeds disturbed sites and its rapid juvenile growth make it very aggressive on abandoned land. Slash pine is a valuable source of wood for the timber and pulp industries, and its copious gum production is valued in the naval stores industry.

Super Select Premium Slash: From our genetically superior Slash Pine seed orchards, we now offer this super volume-producing Slash Pine. It produces an astounding 58 percent more volume per acre at 15 years old. It also has superb resistance to fusiform rust.

2nd Generation Slash Pines

Pitch Canker Resistant Slash: The families that have demonstrated relative resistance to pitch canker in laboratory trees contribute to this seed source. Growth and rust resistance are very similiar to the Premium Slash variety.

Premium Slash: This second-cycle source will produce 29% more volume at age 15 on sites where the fusiform rust hazard is expected to be high.

Select Premium Slash: This source represents the best families "selected" from the premium slash population. It will produce 36% more volume on high rust hazard sites.

Longleaf Pine (Pinus palustris)

Attributes
  • Wildlife food or cover

Longleaf is perhaps the most distinctive of the southern yellow pines. Its long, clear bole, open crown, long needles clustered at the ends of the branchlets, and large silvery buds identify longleaf from a distance. It is a medium to large tree, 80-120 feet in height and 24-30 inches in diameter. It grows best on deep, well-drained, acid, sandy soils, although it can tolerate a variety of sites. Longleaf pine is very intolerant of shade. Its first few years are characterized by little or no above ground growth. A dense tuft of needles is all that appears above the soil surface. This "grass stage" continues until the root system is sufficiently established to support rapid above ground growth. Trees in the grass stage are surprisingly resistant to fire damage, as are the thick-barked mature trees. Longleaf produces valuable lumber and is one of the two species with major roles in the naval stores industry.

Shortleaf Pine

Shortleaf Pine (Pinus echinata)

Shortleaf pine grows naturally in the mountains, piedmont, and upper coastal plain. It reaches an average height of 80-100 feet and 2-3 feet in diameter. It has a clear, well-formed bole, and a small narrowly pyramidal crown. It is generally found on dry upland soils which are neither highly acidic nor strongly alkaline. The species may be less tolerant than loblolly pine, but young trees will endure suppression for many years and yet respond quickly to release. Shortleaf pine is considered slower growing than the other southern pines, and is generally disfavored where other pines are well adapted. It is the most common species regenerated in the northern and western parts of its range and is a valuable timber and pulp species. Shortleaf pine seeds are eaten by squirrels and birds and very mature trees with red heart disease are favored nesting sites for the red-cockaded woodpecker.

Virginia Pine (Pinus virginiana)

A small to medium sized tree that reaches 40-70 feet in height and 12-18 inches in diameter. Virginia pine grows naturally in the upper piedmont and lower elevations of the Appalachian Mountains. Though it occurs on a wide variety of sites, from heavy clays to dry rocky soils, its best development occurs on well-drained loams. It grows poorly on sandy soils. Virginia pine has a shallow root system and is susceptible to wind throw and damage from ice and snow. The species is valued as a source of pulp and its seeds are eaten by birds, squirrels, and other wildlife. Its growth is inferior to the other southern pines and it should not be planted commercially below the upper piedmont. The branches of virginia pine commonly extend to the ground making it valuable as a Christmas tree, and, at close spacing, it makes an excellent hedge or screen.
