Oldest viable seed

There have been several seeds known at different times as the oldest viable seed.

Silene stenophylla (wild)
The Judean date palm "Methuselah" at Ketura, Israel
Sacred Lotus (wild)

Dormancy allows seeds to survive for extended periods, which can aid in seed dispersal and spread out the growth and establishment of seedlings, increasing the likelihood that some of the next generations survive if conditions are not suitable for seedling establishment. Over time, seeds lose viability which is the ability to initiate metabolic activity, cellular growth, and germination. Seeds have many cells and tissues that die over time,[1] and these deaths can be delayed or increased by environmental conditions the seed experiences. Very generally, small seeds, especially from weedy species and annuals are more likely to remain viable in the soil longer than larger perennial seeds.[2] The seeds of some aquatic plants also may remain viable longer in mud because their viability is aided by the aquatic environment which remains cool and moist.[2]



  • In December, 2009, a Turkish newspaper reported a claim that a 4,000-year-old lentil had been successfully germinated.[9]
  • In 1954 Arctic lupine seeds (Lupinus arcticus) were found in the Yukon Territory in glacial sediments believed to be at least 10,000 years old. Seeds were germinated in 1966. Later, new dating techniques revealed that they were likely modern seeds (less than 10 years old) contaminating ancient rodent burrows.[10][11]


  • The oldest carbon-14-dated plant tissue that has grown into a viable adult plant was a Silene stenophylla (narrow-leafed campion), an Arctic flower native to Siberia. The plants were not grown from seeds, which were not viable, but the placenta tissue of three fruits.[13] Radiocarbon dating has confirmed an age of 31,800 ±300 years for the seeds. In 2007, more than 600,000 frozen mature and immature seeds were found buried in 70 squirrel hibernation burrows 38 metres (125 ft) below the permafrost near the banks of the Kolyma River. The Arctic ground squirrels (Urocitellus parryii) believed to have buried the seeds had damaged the mature seeds to prevent germination in the burrow, but three of the immature seeds contained viable placenta tissue, which was successfully grown in vitro. The plants grew, flowered and created viable seeds of their own. The shape of the flowers differed from that of modern S. stenophylla with the petals being longer and more widely spaced than modern versions of the plant. Seeds produced by the regenerated plants germinated at a 100% success rate, compared with 90% for modern plants. Calculations of the γ radiation dose accumulated by the seeds since burial gave a reading of 0.07 kGy, the highest maximal dose recorded for seeds.[14][15][16]

A sapling germinated earlier this year from a 2,000-year-old date palm seed is thriving, according to Israeli researchers who are cultivating the historic plant. "It's 80 centimeters [3 feet] high with nine leaves, and it looks great," said Sarah Sallon, director of the Hadassah Medical Organization's Louis L. Borick Natural Medicine Research Center (NMRC) in Jerusalem.

Carbon dating of the seeds found at Masada revealed that they date from roughly the time of the ancient fortress' siege, in A.D. 73. The seeds were found in storage rooms, and appear to have been stockpiled for the Jews hiding out against the invading Romans. ... The seeds were excavated about 40 years ago, along with skeletons of those who died during the siege. Since then, the seeds had been languishing in a drawer until Sallon and her team decided to attempt to grow them anew. ... Though a few trees have been planted from seeds that are rumored to be older than the Masada ones, the Methuselah tree holds the record for the oldest directly dated seed to be germinated. Scientists determined its age from control seeds taken from the same batch, and from shell fragments from the sprouted seed itself.

Israeli doctors and scientists have succeeded in germinating a date seed nearly 2,000 years old. The seed, nicknamed Methuselah, was taken from an excavation at Masada, the cliff fortress where, in A.D. 73, 960 Jewish zealots died by their own hand, rather than surrender to a Roman assault. The point is to find out what was so exceptional about the original date palm of Judea, much praised in the Bible and the Koran for its shade, food, beauty and medicinal qualities, but long ago destroyed by the crusaders. [Correction: June 15, 2005, Wednesday: An article on Sunday about the successful germination of a 2,000-year-old date seed by Israeli doctors and scientists referred incorrectly to the Koran's mentions of the date palm. They were to the tree in general, not to the date palm of Judea. The article also misstated the timing of the Crusades, when the date palms of Judea were destroyed. The Crusades took place during the Middle Ages, not before.]

An ~1300-yr-old lotus fruit, recovered from an originally cultivated but now dry lakebed in northeastern China, is the oldest germinated and directly 14C-dated fruit known. In 1996, we traveled to the dry lake at Xipaozi Village, China, the source of the old viable fruits.
