Pond pine (Pinus serotina) belongs to the Pinaceae (the Pine family). It is a tall evergreen tree that is native along the Southeastern portion of the Atlantic coastal plain of the United States. This tree grows in wet habitats near ponds, bays, and swamps, and up to 21 m high. The needles are in bundles of three or four, and 15-20 cm long. The almost round cones are 5-8 cm long with small prickles on the scales. Its cones are usually serotinous, requiring forest fires to open.
