My friend, the giant sequoia.

Did you know there are more than 6500 registered locations of sequoia trees "rooted" in Germany?
There's a great web page (in German) where you can look for all the locations of the three sequoia / metasequoia species:

Sequoiadendron giganteum - giant sequoia, Sierra redwood or Wellingtonia
Sequoia sempervirens - Coast Redwood or California Redwood
Metasequoia glyptostroboides - Dawn Redwood

The sequoia community!

These sequoia trees I captured recent days at the reserve Wernhalde at Stuttgart.
All of them are giant sequoias, the oldest of them date from 1864!

Giant Sequoias are the world's largest trees in terms of total volume (technically, only 6 living Giant Sequoia exceed the 42,500 cubic feet (1,200 m3) of the Lost Monarch Coast Redwood tree; see Largest trees). They grow to an average height of 50-85 m (165-280 ft) and 6-8 m (18-24 ft) in diameter. Record trees have been measured to be 94.8 m (311 ft) in height and 17 m (57 ft) in diameter. The oldest known Giant Sequoia based on ring count is 3,500 years old. Sequoia bark is fibrous, furrowed, and may be 90 cm (3 ft) thick at the base of the columnar trunk. It provides significant fire protection for the trees.

The leaves are evergreen, awl-shaped, 3-6 mm long, and arranged spirally on the shoots. The seed cones are 4-7 cm long and mature in 18–20 months, though they typically remain green and closed for up to 20 years; each cone has 30-50 spirally arranged scales, with several seeds on each scale giving an average of 230 seeds per cone. The seed is dark brown, 4-5 mm long and 1 mm broad, with a 1 mm wide yellow-brown wing along each side. Some seed is shed when the cone scales shrink during hot weather in late summer, but most seeds are liberated when the cone dries out from fire heat and/or insect damage.
