Origin of redwood²

First recorded in 1550–60; red ¹ + wood ²

Explanation

Redwoods are a kind of large, ancient evergreen trees commonly found on the coast of California. Coastal redwoods are the tallest living things on Earth. These magnificent trees are made up of three species, Sequoia and Sequoiadendron in California and Oregon, and China's Metasequoia. Redwoods have adapted over millions of years to be resistant to fire and infection, and they can reach heights of over 300 feet. Their name comes from the reddish-brown shade of their wood and bark. In 16th-century Scotland, the unrelated adjective redwood was used to mean "completely deranged."
