une fleur de ... 30000 ans

As far a flowering pot plants go, the Silene stenophylla plant sitting in a corner of a Russian laboratory will not win many awards.

The one award it will win, however, is pretty impressive: The most ancient, viable, multi-cellular, living organism on Earth. The Silene stenophylla was brought back to life using seeds buried by squirrels in Siberian permafrost more than 30,000 years ago.

The seeds have been held in suspended animation by the cold, which has served as a 'frozen gene pool', scientists say.
