Plant seeds

There are about 6 million plant species stored as seeds in about 1,300 gene-banks throughout the world as of 2006. This amount represents a small fraction of the world's biodiversity, and many regions of the world have not been bio-prospected fully. The oldest seed that actually germinated into a viable plant was a 2,000 year old date palm seed, recovered from excavations at Herod the Great's palace in Israel.
