Clip Description

For a seed to stand the best chance of growing into a new plant, it must travel as far away as possible from the plant it came from so that it is not competing for sunlight and nutrients. This movement is called seed dispersal. With most plants rooted to the ground, they must find clever ways to make sure their seeds are spread far and wide.

In this fascinating clip, Sir David Attenborough shows us how a poisonous plant disperses its seeds in a highly explosive way. The plant is called ecballium or the ‘squirting cucumber.’  How will Sir David help the ecballium seeds on their journey away from the parent plant? Watch the clip to find out.
