A corm is an underground plant stem that serves as a storage organ utilized by some plants to survive adverse surface conditions. The largest corm is produced by the titan arum Amorphophallum titanum, native to Indonesia, and commonly weighs around 50 kg. However, the heaviest confirmed example, at the Royal Botanic Garden Edinburgh (RBGE), Scotland, when weighed in 2010 was found to weigh 153.9 kg, thereby taking the record from the previous record holder, in Bonn, Germany.


The previous confirmed record holder for largest corm, also belonging to a titan arum Amorphophallum titanum, weighed 117 kg, and was recorded in 2006 in the Botanical Garden of Bonn in Germany. This species is also known as the corpse flower, being (in)famous for the hideous smell that it releases, reminiscent of rotting flesh, which serves to attracts flies that pollinate it in its native Indonesian homeland.
