Bay Pine

Pinus serotina (PY-nus se-roh-TEE-nuh)

Family: Pinaceae Native Understory

This native plant grows in a full range of soil types, including damp and wet soil with poor drainage. Its form or habit is conical and often has crooked branching with a trunk diameter of about 1 to 2 ft. Its native habitat includes swamps, shallow bays, and ponds on the NC Coastal Plain and eastern Piedmont. Its coarse, heavy wood is used for lumber and pulp. The name, serotina means late, referring to the cones, which remain closed for years before opening. They will open often following a fire. In fact, it is particularly resistant to wildfires; after fires, the seedlings and trees will produce sprouts from the roots. It can even re-sprout after being entirely consumed by a fire, making the resulting clusters of needles on the trunk a very identifiable feature of this tree. Insect, Diseases, and Other Plant Problems: This tree is susceptible to wind damage. More information on Pinus .
