World's largest Living Plant is a Seagrass

High-school textbooks have made us learn that there is a Giant Seqouia tree in Sequoia National Park in California that is over 300 feet tall and is the largest plant on this Earth

Research explorations have identified Pando, a grove of aspen tree Populus tremuloides in Utah as the largest plant. It is a group of 50,000 tree trunks all having single roots spread over an area of 43ha. They originated "clonally" form same root and spread adventitiously in this entire area. Recently, an even bigger flowering plant has been reported in a study by Edgeloe and his team 2022 which is a seagrass. Poseidon's ribbon weed, Posidonia australis inhabiting Shark Bay, Australia is a group of clonally propagated grass having modified root, rhizome, as an anchor spread in an area of 180 km off the coastal regions. And to the surprise, it is a single plant multiplied vegetatively by breaking off its rhizomes and producing clones for propagation since last 4500 years bearing all sorts of climate and environmental fluctuations.
