Cedar Pine

Pinus glabra (PY-nus GLAY-bruh)

Family: Pinaceae Unknown Canopy (>40 ft)

Spruce pine is an evergreen tree in the Pinaceae family that is native from SC south to FL and west to LA. It is often found growing in wetland sites and is different from other pines as it doesn't tend to grow in pine stands. It can grow up to 80 feet tall but is usually 40-50 feet in height. It starts producing cones at 10 years of age. Spruce pine has a beautiful oval-rounded crown with dark green needles. The trunk can be straight but is often bent and twisted if growing in the understory. It will grow in a variety of locations with the exception of areas with fine soils and needs consistent moist to wet soils The seed cones persist on the tree for 2-3 years, providing food for wildlife. Use this tree in moist to wet sites as along streams or ponds. It makes a good windbreak and provides shade. This variety of pine is also used as a Christmas tree. Insect, Diseases, and Other Plant Problems: This tree is susceptible to wind damage. Canker diseases may occasionally cause dieback. Infected branches can be pruned. More information on Pinus .
