English oak has been a popular and well-known species of tree for centuries, admired for its strength, durability and gorgeous appearance. In addition to its scientific name of Quercus robur, there are various synonyms you may come across when referring to this iconic tree. Some of these alternatives include the common oak, pedunculate oak, British oak, or sessile oak. These synonyms represent subtle differences in the species, such as the relationship between leaf and stalk size. However, ultimately they refer to the same magnificent plant that has celebrated in folklore, literature, and mythology for thousands of years.
