Do not confuse with sister-species ◼︎ eastern white pine  Pinus strobus, which has a similar common name.

In the southern 🇺🇸 USA, also called ◼︎ yellow pine.  Although do not confuse with sister-species also sometimes called that:

Part of 🌲︎ pine  genus Pinus in 🌲︎ cedar / fir / hemlock / larch / pine / spruce  family Pinaceae in 🌲︎ conifer  order Pinales.

Native to 🇺🇸 USA Southeast.

🏛🌲︎ State tree of Alabama.

In this area (particularly 🇨🇦 Canada AB BC SK, and 🇺🇸 USA AZ CA CO ID MO MT NV NM OR SD UT WA WI WY):

  • do not move pine logs, stumps, branches, firewood nor untreated lumber
due to possible infestation by the insect mountain pine beetle (MPB)  Dendroctonus ponderosae, which carries various species of 🍄︎ fungus / mushroom  kingdom Fungi.

Uses by native peoples
(Ethnobotany database)

Pinus hosts caterpillars of 247 species
of butterflies and moths, in some areas.
  This plant is also known to be a host for (in areas where invasive) 🐝︎ spotted lanternfly (SLF)  Lycorma delicatula.

As a 🌱︎ seedling, this pine has a 🌾︎ grass stage, where its needles all emerge from a common center near the ground, causing it to look like a bunchgrass, while also developing a long taproot.  This stage might last one to seven years, or even 20.  Only after our plant detects a large increase in available light (perhaps caused by a storm or 🔥︎ low-intensity fire that opened up the forest canopy), our seedling starts to bolt (suddenly grow tall).  Also sharing this strategy are several sister-species of pine, mostly tropical. [1]   The only species likely to be covered in ICSN soon is slash pine  Pinus elliottii.

Thus, longleaf pine's growth is improved by 🔥︎ low-intensity wildfire.  And made worse by 🐖︎ feral pigs.
