Tree 22: Giant sequoia

  • Sequoiadendron giganteum
  • California

Information on the genus and species

Sequoia - The tree was probably named after the son of a Cherokee chief, the inventor of the Cherokee syllabary. It is also believed to be the Cherokee Indian dialect name for the gopher "Oppussum".

Evergreen conifer, a true single-stemmed, columnar giant tree with a great design effect in parks and gardens.

Remnants of the forests decimated by the timber industry can still be found in 72 protected groves on the western slopes of the Sierra Nevada in California up to an altitude of 2,500 meters.

Giant sequoias can live for more than 3,000 years. The largest, called the "General Sherman Tree", is 83.8 meters high and up to 20 meters wide and has a trunk circumference of 31 meters.

The giant trees came to Europe in 1853 and are widely used as large design elements in our parks and gardens.

A special specimen is the coast redwood (Sequoia sempervirens). The tallest is called "Hyporion". It is 115.55 meters high and can be found in the Redwood National Park in California.

Sequoiadendron giganteum

Bark: The soft, brown-reddish, cracked bark can be up to 60 cm thick as protection against forest fires.

Needles: They are short, scaly, blue-green.

In contrast, the needles of the coast redwood "Sequoia sempervirens" are pressed in two rows, like those of yews. (There are two specimens in Redoubt Park.)

Flower: monoecious, male flower: small, yellow globules; female flower: biennial, first green cones, brown cones in the second year, six cm long

Characteristics: frost-hardy, hardy, not drought-tolerant, long-lived, susceptible to lightning strikes

Timber utilization: until the designation of the protected areas, the redwood was rigorously felled especially for the construction industry, for building houses inside and outside and much more.
