Researchers from the Georgia Institute of Technology in the USA used high-speed footage to prove that some plants use raindrops to disperse their seeds sending them as far away as up to 10 times the height of the mother plant.

“Plants with cone-shaped flowers or fruit, sometimes called ‘splash-cups’, disperse their seeds using splashes of falling water. They capture rainwater in their cup-shaped flowers and use the impact of subsequent raindrops to splash out the seed-filled liquid.”

The distance of seed dispersal was dependant on where the raindrop landed & the shape of the flowers.   If the raindrop landed in the centre of the flower, the seed dispersal was not so great. If the raindrop landed on the edge, the seeds could travel five times further.

The article in Australian Geographic has a short video that demonstrates seed dispersal in a raindrop. It’s quite incredible.  See – http://bit.ly/UKMFrf
