In a Nutshell:
* A 2017 study found that trees tend to have a uniform tilt dependent on the hemisphere of their location, leaning on average 8 degrees south in the northern hemisphere and the same angle north in the southern hemisphere.
* Araucaria columnaris is among the most common species of Araucaria planted as an ornamental tree and street tree in warm temperate climates.
* Araucaria columnaris, the Coral reef araucaria, Cook pine, New Caledonia pine, Cook araucaria, or columnar araucaria, is a unique species of conifer in the Araucariaceae family. It is endemic to New Caledonia in the southwestern Pacific, where it was first classified by botanists of Captain James Cook's second voyage of exploration. It is a distinctive narrowly conical tree to 60 metres (200 ft) tall. The female cone is 10-15 cm. long by 7-11 cm. wide.
* The Cook pine, called Christmas Tree in India, can reach 60m in natural habit, but is more commonly grown as a house-plant in pots. The relatively short, mostly horizontal branches are in whorls around the slender, upright to slightly leaning trunk. The branches are lined with cord-like, horizontal branchlets. The branchlets are covered with small, green, incurved, point-tipped, spirally arranged, overlapping leaves. The young leaves are needle-like, while the broader adult leaves are triangular and scale-like.
* The Cook pine is often confused with the Norfolk Island pine because they have a similar appearance. more...
