Meet the Plants That Have Been Cloning Themselves for Thousands of Years

When we think of a plant's lifespan, we usually imagine a tree or flower growing from a seed, living for a number of years and eventually dying. However, some plants follow an entirely different path. Instead of relying solely on seeds, they reproduce by creating genetically identical copies of themselves, allowing the same organism to survive for centuries or even thousands of years. Although individual stems or trunks may die, the underground root system continues producing new shoots, making the organism effectively immortal on a human timescale. These extraordinary plants are among the oldest living organisms on Earth and offer remarkable insights into evolution, resilience and the power of nature.

Plants That Can Clone Themselves for Centuries

What Is Plant Cloning ?

Plant cloning, also known as vegetative reproduction , occurs when a plant produces new growth from roots, stems or underground structures instead of seeds.

The new plants are genetically identical to the original because they arise from the same living tissue. Over time, these clones spread outward, creating enormous colonies that function as a single organism.

This strategy allows plants to survive even when seed production becomes difficult due to harsh climates or limited pollinators.

Pando , the Giant Living Organism

Perhaps the most famous example is Pando, a vast colony of quaking aspens in Utah, United States. At first glance, it appears to be an ordinary forest, but genetic studies have revealed that more than 40,000 tree trunks are connected by a single underground root system.

Scientists estimate that Pando covers about 43 hectares and weighs around 6,000 tonnes, making it one of the heaviest known living organisms on Earth.

While individual trees live for roughly 100 to 150 years, the root system itself may have survived for thousands of years by continually producing new trunks.

Ancient Seagrasses Beneath the Ocean

Cloning is not limited to forests. In 2022, researchers discovered an enormous meadow of Posidonia australis seagrass in Shark Bay, Western Australia.

Genetic analysis showed that the entire meadow had grown from a single seed before expanding through cloning over an area of about 180 square kilometres.
