Most people have heard of Giant Redwoods, possibly as Giant Sequoia and probably know that they originate from somewhere in America. They are relatively rare, but can actually be found in many towns in British towns and isles.
If you come across a large Giant redwood in the UK it's only going to be 100 to 150 years old based on the fact they were only introduced in the 1850's. They can grow to an average height of 50–85 m.
An interesting fact about Redwood is that the earliest redwoods were seen on Earth shortly after the dinosaurs and before flowers, birds, spiders and, humans. Redwoods have been around for 240 million years, compared to about 200,000 years for “modern” humans.
Officially, the oldest redwood is at least 2,200 years old, and they are tallest tree on the on Earth. Local coast redwood tree can grow up to 300 feet or more, the tallest tree on Earth.
Here is a young Redwood in Vernon Park in Offerton (Stockport).
It is hard to say how tall it is, but it is enormous.
