In addition to sexual reproduction, seagrasses also have an asexual option. They send rhizomes out from the base of thriving plants and can, very gradually, cover large areas of the coastal sea floor. One such patch by a Mediterranean seagrass, Posidonia oceanic, is thought to be about 200,000 years old. Other familiar plants that spread by rhizomes is the bamboo, bearded iris, snake plants and wild type (orange) daylily.
