description

The giant eucalyptus grows as an evergreen tree that can reach an age of around 400 years. The giant eucalyptus is extremely fast-growing; in preferred locations it can reach heights of 65 meters in 50 years. It is considered the tallest deciduous tree in the world, possibly even the tallest tree at all. A specimen felled in 1872 was 132 meters high. The highest currently living specimen "Centurion", standing in Tasmania , is "only" 99.6 meters high and thus significantly smaller than several more than 110 meters high specimens of the coastal redwood ( Sequoia sempervirens ) in California , and still smaller than a 2018 Yellow Meranti tree on Borneo , measured to a height of 100.8 m , which is currently the highest known living deciduous tree.

The giant eucalyptus forms a narrow treetop on a straight trunk. The bark is gray and roughly furrowed at the lowest 5 to 15 meters, above it rather smooth.

The leaves are divided into a petiole and a leaf blade. The petiole is reddish. The simple green to gray-green leaf blade is 9 to 14 centimeters long and 1.5 to 2.5 centimeters wide and lanceolate to sickle-shaped and ends in a pronounced tip. The leaf margin is smooth.

The 9 to 15 flowers sit together in an inflorescence. The hermaphrodite flower is radially symmetrical with a diameter of about 1 centimeter. The capsule fruits are 5 to 9 millimeters long and 4 to 7 millimeters wide.

Occurrence

The home of the giant eucalyptus is in southeastern Australia in the state of Victoria and on the island of Tasmania . It grows there in cooler regions with a high annual rainfall of over 1200 mm. Its occurrences range at altitudes of up to 1000 meters.

use

The giant eucalyptus is largely grown for forestry; the stocks of remaining jungle areas with old giant trees are noticeably dwindling due to deforestation. The wood of the giant eucalyptus is used, among other things, for paper production.
