What is Poseidon sacred tree?

Poseidon's sacred tree is the olive tree, which is often associated with Athena, the goddess of wisdom and warfare, who competed with Poseidon for the patronage of Athens. However, in some myths, Poseidon is linked to other plants, such as the seaweed or various coastal plants. The olive tree symbolizes peace and prosperity, reflecting the dual nature of Poseidon as both a god of the sea and a protector of cities. While he is primarily known for his connection to water, the olive tree represents the interconnectedness of land and sea in ancient Greek culture.
