Are Redwoods & Sequoias the Same?

Redwoods and sequoias are similar but not the same.

Redwoods and sequoias are both large trees that often get confused for one another. While the two trees have their fair share of similarities, they are technically not the same tree. Impossible to distinguish for some, redwoods and sequoias differ in their life spans, potential size and more. Both are found most abundantly in Northern California forests.

Similarities

Redwood and sequoia trees share many similarities. Both are famous due to their natural presence in California forests. Redwoods thrive along California's northern coastline due to the moisture provided by humidity. Sequoias are found near the Sierra Nevada mountains, a location which has enough dryness to satisfy their reproduction requirements. Both also have national parks named after them, and both have a similar red tint to their bark. The scientific names of both trees are also similar, which may add to the notion that they are one and the same tree. Redwood trees have a scientific name of Sequoia sempervirens -- Sequoiadendron gigantea is the sequoia's scientific name.

Size

While the bark of a redwood can be up to 1 foot thick, the bark of a sequoia can be up to 3 feet thick. Branches of redwood trees can be as thick as 5 feet, while sequoia branches can be as thick as 8 feet. Redwoods are taller than sequoia trees, though both exceed 300 feet. Sequoias have much wider trunks, which makes them bigger than redwoods -- a single sequoia tree can weigh more than 2.5 million lbs., while redwoods generally do not get heavier than 1.5 million lbs.

Cones and Needles

Redwoods have circular cones that lead to reproduction every fall, while sequoia trees have oval-shaped cones and take as long as two years to reproduce. Redwoods use both seeds and sprouts to create more trees, while sequoias use just seeds. The needles that come out from redwood branches take on a white appearance, while sequoia needles are silvery and green. Although the colors are similar, they are easy to differentiate when compared directly with one another.

Lifespan and Population

It may take longer for sequoias to reproduce, but they are also capable of outliving redwood trees by more than 1,000 years. Sequoias can live more than 3,000 years, while redwoods typically top out at around 2,000.
