Plant Description

Plant Description The Posidonia oceanica is an aquatic plant that belongs to the Posidoniaceae family. It forms dense underwater meadows with long and narrow leaves, up to one meter in length. Its leaves, of an intense green, are born from a rhizomatous stem that extends horizontally along the seabed, anchoring itself firmly to the substrate with dense root systems. The flowers of Posidonia are small and inconspicuous, yellow or green in color, and arise directly from the rhizome. The fruits, known as "sea olives", are round and floating, which facilitates their dispersal through sea currents. This plant can reach a considerable age, with some individuals estimated to be more than 100,000 years old, making it one of the longest-lived organisms on the planet.
