Pinus elliottii
Origin: The species is native to the southeastern United States.

Opinion
"
This plant, native to the United States, has been produced in other countries for commercial cultivation due to its highly desirable characteristics as high quality wood and resin for raw materials in different industries. Its good adaptability to different conditions and rapid growth distinguish it from other pines. Although little used in landscape, it has potential for use in naturalization of landscapes or parks.

Description and Growing Information
Flowering Period
| General Description |
| Pinus elliotti was named after Stephen Elliot, a South Carolina botanist who distinguished the species from P. taeda. This is a fast growing plant, which is adapted to different soil conditions and tolerant to stress conditions, however it is susceptible to diseases and pests. It is highly desired for commercial plantations both for the quality of its wood and resin, and for the ease of cultivation |
| Landscape |
| The species is used in landscapes with the intention of naturalizing the scenery. It is used with good results for reforestation or recuperation of degraded areas. It is also widely used for the production of resin for the extraction of turpentine, raw material for making industrial solvents, cosmetics and other products. Its wood is used for furniture and civil construction and also in the production of softwood pulp and wood fiber sheets. |
| Cultivation |
| he species is well adapted to different soil conditions, tolerates from clay to sandy soils, although grows best in soils with good drainage and some moisture. It is resistant to drought conditions and It thrives in full sun or half shade. High pH is prejudicial to the species, however the species tolerate acidic soil and. Pinus elliotti presents good tolerance to poor, saline soils, as well as to drought. Studies show that air pollution and acid rain cause a decrease in the growth and population of Pinus elliottii. |
| Shape |
| The species is intermediate between oval and pyramidal, and irregular, presenting a more pyramidal shape when young. The branches are sparse and not very dense. |
| Growth |
| Medium |
| ID Characteristic |
| Pinus elliotti has leaves with long needles in groups of 2 or 3, with thick reddish-brown bark that forms plates. Another remarkable characteristic is the formation of a large layer of fascicles on the ground due to the constant fall of the leaves and the difficulty of its decomposition. |
| Pests |
| The diseases of greatest concern to Pinus elliotti are fusiform rust and annosus root rot, which affect the stems and roots and can cause the plant to die. Pinus elliotti is also susceptible to Pine needle miner, Pine needle scale, Pine spittle bug, spruce mites, sawfly larvae. Bark beetles can be a more serious problem, especially . It is also susceptible to fusiform rust, pitch canker. In the seedling production process, some fungi cause great damage, like Fusarium oxysporum, which infects the seed and causes toppling after emergence of the plant. High pH and planting in construction areas are associated with severe chlorosis problems, with yellowing of the plant and eventual death. |
| Habitat |
| The species occurs naturally along rivers and on the shores of marshes and lakes in hot and humid areas, with humid summers and dry springs and autumns and at altitudes of up to 150 m. The species occurs naturally in flatwoods in northern Florida and southern Georgia. |
| Bark/Stem Description |
| In the first stages the bark is grayish brown and presents furrows, and becomes reddish brown in the following stages, as the bark becomes more thicker with 2 to 4 cm it forms plates with thin scales that flake off showing a dark orange colour. Its trunk can reach up to 0.8m in diameter and can be straight or contorted |
| Flower/Leaf Bud Description |
| The leaf buds are silvery brown and measure 1.5 to 2 cm, with a cylindrical shape and fringed scale margins. |
| Leaf Description |
| The leaves are needle-shaped, with groups of 2 in younger individuals and 3 in older ones. They are alternate, with entire and simple margins. The veining is parallel, with dark green, fragrant leaves. The leaf blade is 15 to 30 cm long. |
| Flower Description |
| This species does not have flowers, but has strobiles that occur in clusters of 12 or more and begin to develop in June and last a few weeks. The strobile are inserted at the tip of the lateral branches, small, 2 to 3 cm in size and red and yellow in colour. Pollination is by wind and pollen is released between January and February. |
| Fruit Description |
| The cones are persistent and scabby, reddish-brown, elongated oval, measuring approximately 8 to 15 cm, and 2.5 to 7.5 cm in diameter. Squirrels help disperse the seeds, as they are attracted to the cones |
| Colour Description |
| Pinus elliotti is an evergreen with dark green leaves that do not change colour during the year. The trunks are reddish brown. The cones are woody brown, and the inflorescences are yellow and not showy. |
| Texture Description |
| Fine, no changes between seasons. |
| Notable Specimens |
| The State Forest Edmundo Navarro de Andrade, in Rio Claro, Brazil, is a conservation center that has been used in the past for research on economically important timber species, the site presents a very large collection of eucalyptus and pine trees, including adult Pinus elliotti specimens. |
| Propagation |
| he most common method of propagation is through seeds, which germinate in about 15 to 20 days and do not require specific previous treatment. The use of mycorrhizae associated with sowing increases the vigor of the plant. After sowing, about 7 to 8 months, when the plant reaches 30 cm in height, it can be transplanted to its definitive location. Another form of successful propagation is through micropropagation, a method that has been used for the production of seedlings of high quality genotypes used in commercial timber production. |
| Ethnobotanical Uses (Disclaimer) |
| Pinus elliottii has been used traditionally as folk medicine for rheumatism, inflammation of the intestine, colds, gonorrhea and others through the consumption of the Turpentine present in the resin. |
