{{Main|List of oldest trees}}
[[Plant]]s are referred to as [[Annual plant|annuals]] which live only one year, [[Biennial plant|biennials]] which live two years, and [[Perennial plant|perennials]] which live longer than that. The longest-lived perennials, woody-stemmed plants such as trees and bushes, often live for hundreds and even thousands of years (one may question whether or not they may die of old age). A [[giant sequoia]], [[General Sherman Tree|General Sherman]], is alive and well in its third [[millennium]]. A [[Great Basin Bristlecone Pine]] called [[Methuselah (pine tree)|Methuselah]] is {{age|-2832|8|5|format=commas}} years old.<ref>{{Cite web|title=Pinus longaeva (Great Basin bristlecone pine) description - The Gymnosperm Database|url=https://www.conifers.org/pi/Pinus_longaeva.php|access-date=2021-03-01|website=www.conifers.org}}</ref> Another Bristlecone Pine called [[Prometheus (tree)|Prometheus]] was a little older still, showing 4,862 years of growth rings. The exact age of Prometheus, however, remains unknown as it is likely that growth rings did not form every year due to the harsh environment in which it grew but it was estimated to be ~4,900 years old when it was cut down in 1964.<ref>{{Cite web |last1=Baker |first1=Mailing Address: 100 Great Basin National Park |last2=pm |first2=NV 89311 Phone: 775-234-7331 Available 8:00 am- 4:00 |last3=Thanksgiving |first3=Monday through Friday Closed on |last4=Christmas |last5=Us |first5=New Year's Day Contact |title=The Prometheus Story - Great Basin National Park (U.S. National Park Service) |url=https://www.nps.gov/grba/learn/historyculture/the-prometheus-story.htm |access-date=2022-03-20 |website=www.nps.gov |language=en}}</ref> The oldest known plant (possibly oldest living thing) is a clonal Quaking Aspen (''[[Populus tremuloides]]'') tree colony in the [[Fishlake National Forest]] in Utah called [[Pando (tree)|Pando]] at about 16,000 years. [[Lichen]], a symbiotic algae and fungal proto-plant, such as ''[[Rhizocarpon geographicum]]'' can live upwards of 10,000 years.{{cn|date=November 2024}}
