The Oak tree is one of the most loved trees in the world, and with good reason. It’s a symbol of strength, morale, resistance and knowledge. Throughout history, the Oak has been represented in different mythologies and sometimes linked to powerful gods (in Greek mythology it was a symbol of Zeus, the God of Thunder.) The oak is considered a cosmic storehouse of wisdom embodied in its towering strength. It grows slowly, but surely at its own rate. Oak is often associated with honor, nobility, and wisdom as well thanks to its size and longevity. Oaks are known to easily surpass 300 years of age making it a powerful life-affirming symbol.
