Oak Symbolism and Meaning

What is an Oak Tree?

Oaks are sturdy trees with leaves that can be either deciduous or evergreen. The leaves are often arranged spirally and may have lobed or serrated edges. Some types of oaks keep their dead leaves until spring. In the spring, a single oak tree produces both male and female flowers, making it monoecious. The fruit of an oak tree is a nut called an acorn, which symbolizes fertility and rebirth in Celtic mythology. Acorns and leaves of oaks contain tannic acid, which helps protect the tree against fungi and insects. There are around 500 different types of oak trees.

According to the Roman scholar Pliny the Elder, Druids considered oak trees sacred, believing they were sent from the heavens. They conducted religious rituals and festivities under the oak trees and even climbed them to harvest crops.

Like their ancestors, the Vikings took care of a particular oak they called “Grandfather Oak.” Other trees surrounded this tree in a sacred grove, which they treated with great respect during religious ceremonies. The wood from the Oak was hard and durable, not easily shaped, reflecting the tree’s strength. It was considered sacred and, if crafted with care, could be passed down through generations like a timeless family treasure. When people say “Solid as an oak,” they mean something that can resist change or outside influences, something made to last and stay strong.
