They grow to an average height of 70-85 m (230-280 ft) and 5-7 m (16-23 ft) in diameter. Record trees have been reported to be 93.6 m (307 ft) in height and 8.85 m (29 ft) in diameter. The oldest known Giant Sequoia based on ring count is 3,200 years old.
The leaves are evergreen, awl-shaped, 3-6 mm long
The seed cones are 4-7 cm long and mature in 18-20 months, each cone has 30-50 spirally arranged scales. On each scale are some seeds so it is giving an average of 230 seeds per cone. Young trees start to bear cones at the age of 20 years.

The Giant Sequoias are having difficulty reproducing in their original habitat (and very rarely reproduce in zealand-australia-canada/" class="wiki-link" title="Viac o: immigration">immigration/" class="wiki-link" title="Viac o: cultivation">cultivation) due to the seeds only being able to grow successfully in mineral soils in full sunlight, free from competing vegetation. They require periodic wildfire to clear competing vegetation and soil humus before successful regeneration can occur. Without fire, shade-loving species will crowd out young sequoia seedlings, and sequoia seeds will not germinate.
