Spruce pine is an evergreen tree in the Pinaceae family that is native from SC south to FL and west to LA.

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.
