The Spruce Pine is native to coastal South Carolina, southern Georgia & Alabama & Mississippi, northern Florida, and a little of southeast Louisiana next to MS, often growing with hardwood trees. It gets its species name of "glabra" from the smooth, waxy, hairless shoots and branches. It has soft dark green needles in fascicles of 2 that are about 1.5 to 3 inches long. Its globose cones are about 2 to 3.5 inches long and scales are tipped with a minute prickle that often is deciduous. Its young bark is gray and smooth, then grey-brown and fissured and scaly, then grey and irregularly plated. It forms an irregular crown and has either straight or twisted, curved trunks to about 2 to 3 feet in diameter, and the tree is breakage resistant. It grows about 1 foot/year. It is recommended as a reclamation plant, a Christmas tree, a wind break-screen, for parking lot islands or around parking lots, or a picturesque yard tree. It is very similar to the Virginia, Sand, Pond, and Shortleaf Pines, and even the Scots and Japanese Red Pines of Eurasia.
