Posidonia seaweed
Posidonia seagrass is a plant endemic to the Mediterranean Sea. It is an asexual seagrass with a lifespan of more than 100,000 years and is currently endangered. It reproduces by the division of meristems. Its rhizomes grow slowly, but can spread for several kilometers over a long period of time. It is considered to be the longest-lived organism in the world so far.
- Pando Tree
The Pando tree is the oldest tree on Earth and one of the long-lived plants. Although it is not the oldest single tree in essence, this asexual trembling aspen forest in Utah is a real ancient tree. The huge branch “Pando” began to sprout at least 80,000 years ago, when our human ancestors were still living in Africa. But some people believe that this forest may have a history of millions of years, which means that Pando is 800,000 years earlier than the earliest Homo sapiens. Weighing 6,615 tons, “Pando” is also the heaviest organism on Earth.
- Tasmanian Roshan Longyan
In 1937, naturalist Charlie Dunson King saw unknown creatures in the south of Tasmania, Australia. In 1965, King encountered that kind of tree again 5,000 meters away from the original place, so he sent some samples to the Tasmanian Museum for identification. After identification, it was found that the history of some leaf fossils was at least 43,000 years. According to the upper limit of the estimate, when this tree dropped its fossilized leaves, modern Homo sapiens had just appeared in Africa. - Jurupa Oak
朱鲁帕橡树源自冰河时代末期，已有1.3万年的历史，极有可能是无性繁殖，证实它们属于冰河时期植物的证据是它们具有高比率的“橡子流产”，这些植物无法生长出橡子果实，它们基本上是“不育植物”。根据科学家探测，这种橡树在冰河时代就已经出现了。
5、云杉
Spruce is a tree species unique to China. It is found in southwestern Shaanxi (Fengxian), eastern Gansu (Liangdang) and the Bailong River Basin. Spruce is a very long-lived tree. In February 2014, Swedish scientists discovered a 9,500-year-old spruce on a mountain range, which is considered one of the “oldest” trees in the world. It is still full of vitality and is continuing to grow. I think there may be older trees in our country, but they have not been discovered yet.
- Dragon Blood Tree
龙血树原产加那利群岛、热带非洲。其喜阳光充足，也很耐阴，喜高温多湿环境，宜室内栽培，龙血树植株挺拔、素雅、朴实、雄伟，富有热带风情，大型植株可布置于庭院、大堂、客厅，小型植株和水养植株适于装饰书房、卧室等，世界上最长寿的龙血树8000多岁，可惜的是在1868年毁于一场风灾，这真是人类的一大损失啊！
7、银杏树
Ginkgo, also known as white fruit tree and maidenhair tree, was once one of the rare tree species that only survived in my country and is known as a “living fossil”. The fruits and leaves of the ginkgo tree have high medicinal and edible value. The ginkgo trees cultivated in various places are hundreds of years old or more than a thousand years old. They are cultivated in gardens in Korea, Japan, Europe, and the United States. The largest ginkgo tree in the world is in Fuquan, Guizhou. It is about 5,000 to 6,000 years old and is one of the longest-lived plants. It has a root diameter of 5.8 meters, a tree height of 50 meters, and a breast diameter of 4.79 meters. It takes 13 people to hug it. It was included in the Shanghai Guinness Book of Records in 2001 and is known as the world’s largest ginkgo tree.
8. Baobab
Baobab, also known as Baobab tree, Baobab tree or sour gourd tree, is a large deciduous tree of the Bombacaceae family and the genus Adansonia. It is distributed in tropical or subtropical African countries such as South Africa, Botswana, Tanzania and Madagascar, and its distribution is limited to hot and dry areas. Baobab is also one of the oldest plants in the plant world. Even in the harsh environment of arid savannah, its life span can still reach about 5,000 years. According to relevant records, in the 18th century, the famous French botanist Adamson saw some Baobab trees in Africa, the oldest of which had lived for 5,500 years. Because local folklore says that Baobab is a “sacred tree”, it is protected by people.
- Foxtail pine
Bristlecone pines can be roughly divided into two categories. One is called mountain bristlecone pine, which is mainly distributed in Colorado, Arizona and New Mexico in the United States. The other is called intermountain bristlecone pine, which is mostly distributed in California, Nevada and Utah in the western United States. The intermountain bristlecone pine living in the White Mountains of California is the oldest. This subalpine tree species living at an altitude of about 3,000 meters is truly an immortal pine. The oldest one is called the Methuselah tree. It is a 4,800-year-old Great Basin bristlecone pine that grows in Methuselah Alley in Nevada, USA. There is also an older tree here, its name is Prometheus, but it was cut down in 1964 because it was severely rotten, which is a pity.
- Cypress
Cypress is widely distributed in China, from Inner Mongolia and Jilin in the north to Guangdong and northern Guangxi in the south. It is cultivated throughout the country. It is an excellent gardening tree species and a symbol of longevity and immortality. In Abaku, Iran, there is a 4,000-year-old ancient cypress tree called the Sayibaku tree. This tree has a special status in the hearts of all Iranians and has a strong religious significance.
- Chilean cypress
Chilean cypress is native to southern Chile and southern Argentina. In the wild, it can grow into the oldest and tallest trees in the world. It is generally believed that Chilean cypress is a close relative of the giant redwood distributed in the south of North America. It is believed that the oldest known Chilean cypress is about 4,000 years old, and many trees that are 2,000 to 3,000 years old have been discovered. People believe that this tree species is related to the North American redwood and is the oldest and tallest tree in the world.
- Baldcypress
Baldcypress is native to North America and Mexico. It is now introduced and cultivated in Guangzhou, Hangzhou, Shanghai, Nanjing, Wuhan, and Fujian, China. It has lush branches and leaves, leaves fall late in autumn, and a majestic and beautiful crown. It is a beautiful garden and road greening tree species. This baldcypress in Florida, USA is also called the “Senator Tree”. It is 3,400 to 3,500 years old. It is one of the world’s long-lived plants, the largest tree of its kind in the United States, and the largest ancient tree east of the Mississippi River.
- Giant Sequoia
The giant sequoia, commonly known as the world’s grandfather, is the only species of the genus Sequoia in the family Taxodiaceae. It is the thickest of all trees. It is not only the largest redwood, but also the largest living organism on earth. There are giant sequoias in Sequoia National Park in the United States. The age of this giant sequoia can reach 2,000 to 4,000 years. There is a tree called General Shiaman. In 1989, the height was 83.83 meters. The circumference of the trunk measured from 1.4 meters above the ground was 31.3 meters. It is estimated that the total weight of this General giant tree is 1,000 tons, making it the largest and heaviest tree in the world.
- Red cypress
Red cypress, also known as Taiwan red cypress, pine cypress, pine cypress, thin bark, water ancient cypress, Benihi, is now endangered and is a unique tree species in Taiwan, China. In Taiwan, red cypress is also honored as “sacred tree”. It is a plant belonging to the genus Chamaecyparis in the gymnosperm family. Its branches and leaves are a bit like Chamaecyparis. Red cypress can reach a height of more than 60 meters and a breast diameter of 6.5 meters. It is another big tree second only to the “world grandfather” in California, USA-redwood. Alishan, Taiwan, preserves a big tree called “sacred tree”. It is 57 meters high, 6.5 meters in diameter on the ground, with a volume of about 504 cubic meters and a tree age of about 3,000 years. It is rare in the world and has excellent material. It is a precious economic material in Taiwan.
- Thousand Years Orchid
Welwitschia, also known as 100-year-old leaf, 100-year-old orchid, and 100-year-old leaf, is the only species of the Welwitschia family of the gymnosperm phylum. The distribution range of Welwitschia is extremely narrow and can only be found in the narrow coastal desert in southwest Africa. It is a kind of plant “living fossil” left over from ancient times and is very precious. Although Welwitschia grows in an environment where heavy rain is very rare, due to the influence of the marine climate, drizzles often visit the desert. Therefore, the Welwitschia in the desert not only survives drought, but can live for thousands of years, forming the most precious plant landscape in the world. The oldest Welwitschia known so far has lived for more than 2,000 years.
- Desert Ironwood
The desert ironwood is a plant that can only be found in the Sonoran Desert in North America. As one of the few tall tree species in the local desert, the desert ironwood is an extremely important part of the local ecosystem. It provides shelter for many other creatures and is one of the important ecological indicator species. The desert ironwood manages to survive in the dry and harsh environment of the Sonoran Desert, so it grows slowly and takes hundreds or even thousands of years to grow into a large tree. Its longest lifespan can exceed 2,000 years.
