Propagation
Sow fresh seed during spring in a well-drained media.

Take soft tip or semi hardwood cuttings during summer to autumn.

Note:
Care should be taken when selecting a sight and the tree has vigorous roots that can lift concrete and block drains.

Botanic information
Leaf: The leaves are narrow-lanceolate and are pressed closely to the branches or slightly spreading. The apex is acuminate and the leaves are arranged spiraly along the stem pointing forward and are grey-green underneath.

Flower: The erect female ovoid cones are mid-green and the male flowers appear abundantly as little yellow beads during spring.

Fruit: The bluntly ovoid female cones have diamond shaped scales that have a central depression and the seeds are small with a flat wing. It takes two years for the seeds to mature.

Note:
There is one of these trees (Sequoiadendron giganteum) that are named commonly as General Sherman. It is the largest living thing on Earth; here are some statics to try to allow you to understand how big this tree is. Compared to the largest whale ever caught, which weight 174 tons, this tree weighs 2,145 tones with a height of 83m (272ft) and a girth of 24m (79ft). It would produce 600,000 board feet of timber and has lived for over 3,800 years. The bark is up to 50cm (20in) thick and the wood seems indestructible, as trees that fell 200 years ago are still intact.
