The oldest colony of plants is called Pando which is a colony of trees that are all clones of one another in Utah, USA, it is thought to be 80,000 years old. The oldest individual plant seems to be the Jurupa oak in California that is thought to be 13,000 years old.
I read a paper talking about 3 dwarf willows growing on some Italian mountaintops that are at least 2,000 years old, but maybe up to 18,000. Itโs hard for us to say which exact plant is the oldest!
