King's Lomatia is unusual because all of the remaining plants are genetically identical. Because it has three sets of chromosomes (a triploid) and is therefore sterile, reproduction occurs only vegetatively: when a branch falls, that branch grows new roots, establishing a new plant that is genetically identical to its parent.
Although all the plants are technically separate in that each has its own root system, they are collectively considered to be one of the oldest living plant clones. Each plant's life span is approximately 300 years, but the plant has been cloning itself for at least 43,600 years (possibly up to 135,000 years). This estimate is based on the radiocarbon dating of fossilised leaf fragments that were found 8.5 km away. The fossilised fragments are identical to the contemporary plant in cell structure and shape, which indicates that both plants are triploid and therefore clones due to the extreme rarity of the occurrence of triploidy.

Kings Lomatia deserves its own beautiful plate by a master ceramicist.
