The longleaf pine (Pinus palustris) is a pine species native to the Southeastern United States, found along the coastal plain from East Texas to southern Virginia, extending into northern and central Florida. [3]
Examples of their use includes seasonal wreaths and decorations, fire starters, bird feeders, toys, etc. [13] An intriguing derivation of the impossible bottle mechanical puzzle takes advantage of the fact that pine cones open and close based on their level of dryness. In constructing a display, a closed, damp cone of suitable size is inserted ...
The bristlecone pine's root system is mostly composed of highly branched, shallow roots, while a few large, branching roots provide structural support. The bristlecone pine is extremely drought tolerant due to its branched shallow root system, its waxy needles, and thick needle cuticles that aid in water retention. [8] Gnarled bristlecone pine wood

Each plant may be a few inches tall, and pine-cone-shaped or cylindrical. The plant above ground is almost entirely made up of its inflorescence, a tightly packed column of thick cup-shaped flowers. The groundcone produces haustoria which penetrate the roots of its host and provide it with water and nutrients.
[10] [11] A population on the Maine coast is apparently not reliant on fire for reproduction, [12] and some stands have developed several age classes. [13] Populations with lower serotiny are often found on soils that are in some way limiting to faster-growing competition, such as soils shallow to bedrock, shallow to water table, or very young ...
Western white pine is a large tree, regularly growing to 30–50 metres (98–164 ft) tall. It is a member of the white pine group, Pinus subgenus Strobus, and like all members of that group, the leaves ('needles') are in fascicles (bundles) of five, [5] with a deciduous sheath.
