The loblolly pine is a tall evergreen tree with long, thin needles and scaly bark. It grows along the edges of the Chesapeake Bay and its tidal rivers and wetlands.
Appearance
Long, thin, dark green or greenish-yellow needles that grow on the loblolly pine in bundles of three. The tree's brown, oval cones grow to 3 to 6 inches and have short thorns. Its bark is dark brown or brownish-red bark and separates into scaly, deeply furrowed plates as the tree matures. Its tall, straight trunk has no knots for up to 30 feet high. Loblolly pines will grow 70 to 90 feet tall.
Reproduction and Life Cycle
Reproductive buds form in June and flower in July to August. Male and female buds develop in October, but remain dormant until early February. Male buds are about one inch long and are greenish, yellowish or reddish. They form clusters on the previous year’s growth. Female buds are oval-shaped and slightly smaller. They form on new growth and are fertilized the following spring. Cones, which contain the tree’s seeds, mature by the second October after flowering begins. Loblolly pines can live as long as 275 years.
