Information on Australian Pine Trees
Information on Australian Pine Trees. Australian pine trees -- known scientifically as Casuarina equisetifolia -- are tall, delicate trees native to Oceania and southern Asia. They are not true pines, though they resemble them. Since their introduction to Florida in the 1800s, they have competed with native plants.
Australian pine trees -- known scientifically as Casuarina equisetifolia -- are tall, delicate trees native to Oceania and southern Asia. They are not true pines, though they resemble them. Since their introduction to Florida in the 1800s, they have competed with native plants.
Appearance
Despite their wispy look, Australian pines sometimes soar to heights over 100 feet. They also have spindly leaves that look like pine needles and produce small fruits that resembles cones, which explains their nickname of "pine."
Growing Conditions
Australian pines grow in coastal areas, such as sand dunes, beaches and rocky places by the sea. Their roots produce nitrogen, which enriches poor soils and controls erosion.
Problems
The fast-growing Australian pine trees compete with surrounding plants, forcing out native varieties. The leaves of the trees are full of chemicals that sometimes prevent other plants from growing under them. This has led to their status as invasive plants in many areas of Florida, according to University of Florida IFAS Extension.
