Northern red oak is not a native species – it grows wild in North America. Introduced in Europe in the 18^th century and has naturalized in most Western and Central European countries. In Latvia, northern red oak can grow up to 25 m long, but in natural conditions in North American forests this species can reach up to 40 m in length. In autumn, northern red oaks are especially beautiful – their leaves turn red, so they are often used in greenery. In recent years, the migration of this species into the wild has been observed in Latvia.
