Sequoiadendron giganteum

Small specimens are 1.0-1.5m tall.

Sequoiadendron giganteum, also known as Wellingtonia, is an absolutely spectacular tree. It is long-lived and huge and holds the distinction of being the largest living thing on the Earth by volume! It can live for more than 3000 years!  

This phenomenal specimen is native to California, where it grows on the slopes of the Sierra Nevada. 

Wellingtonia is classified as an evergreen conifer. Its small leaves are light bluey-green, awl-shaped, and arranged spirally on the shoot.

The seed cones are long and green. They usually mature in 18-20 months. However, they typically remain green and present on a single tree for up to 20 years. The cones are forced to release the seed either due to fire or insects damaging the cones. This can also happen when the cone scales shrink during hot weather.

The bark of the Sequoiadendron giganteum is equally as magnificent as the rest of the tree, it is deeply furrowed, which a spongy feel and flaky look to it.

 Wellingtonia are bright brown-red in colour. They have a densely branched structure and remain conical in shape while maturing. 

As the tree ages, the crown spreads more widely, and the branches become more and more downswept. 

The national champion in the USA, situated neatly in Sequoia National Park, is 36m wide and a monumental 92m high! Given access to water at a young age, this tree will thrive in all soils that drain; they will not enjoy having their roots sit in water continuously; however, they do enjoy a constant supply of water.

As the size of Sequoiadendron suggests, it is not a tree that should be planted casually and is therefore best placed where there is ample space for the future, suitable for parklands and estates only.

Mature Height: 20m+
