Dandelion Seeds Reveal Never-Before-Seen Form Of Flight

Cynthia McKanzie – MessageToEagle.com – Plants are astonishing in a number of ways and their abilities seem endless. Not only can plants sing, dance, avoid predators and much more, but they also contain hidden maps and surprises that reveal they share many similar properties with humans. The secret world of plants is truly amazing and full of surprises.

Now researchers have discovered that Dandelion seeds fly using ‘impossible’ method never before seen in nature.

The seeds contain a lot of open space, which seems to be the key to sustaining flight.

The discovery, which confirms the common plant among the natural world’s best fliers, shows that movement of air around and within its parachute-shaped bundle of bristles enables seeds to travel great distances — often a kilometer or more, kept afloat entirely by wind power.

Researchers from the University of Edinburgh carried out experiments to better understand why dandelion seeds fly so well, despite their parachute structure being largely made up of empty space.

Their study revealed that a ring-shaped air bubble forms as air moves through the bristles, enhancing the drag that slows each seed’s descent to the ground.

This newly found form of air bubble — which the scientists have named the separated vortex ring — is physically detached from the bristles and is stabilized by air flowing through it.

The amount of air flowing through, which is critical for keeping the bubble stable and directly above the seed in flight, is precisely controlled by the spacing of the bristles.

This flight mechanism of the bristly parachute underpins the seeds’ steady flight. It is four times more efficient than what is possible with conventional parachute design, according to the research.


Researchers suggest that the dandelion’s porous parachute might inspire the development of small-scale drones that require little or no power consumption. Such drones could be useful for remote sensing or air pollution monitoring.

“Taking a closer look at the ingenious structures in nature — like the dandelion’s parachute — can reveal novel insights. We found a natural solution for flight that minimizes the material and energy costs, which can be applied to engineering of sustainable technology,” Dr Cathal Cummins, of the University of Edinburgh’s Schools of Biological Sciences and Engineering said in a press statement.
