Seeds that dig themselves like a drill

An ordinary cute flower called ‘Chrysanthemum Jwisoni’.

However, the structure of the seed looks like it should not exist on Earth.

After the flowers fall, tall stems sprout in their place.

At some point, the ends started to get twisted.

It bounces like a spring and flies away.

It falls to the ground and looks like this.

And when it rains, the gimmick of this seed begins.

It suddenly spins around on its own.

(When moisture (rainwater) touches it, it untwists and rotates with that force)

The twisted tail retains moisture and the seeds penetrate the ground like a drill.

The drilling is not just done; the tail is tangled at the end.

It guides the angle of incidence of the seed to be close to vertical as it touches and pushes against the ground.

As a result, with such beautiful drilling, about 1.5 times the diameter of the seed,

The seeds are planted at the most optimal depth.

But that spring energy is not infinite.

There are many instances where, due to bad luck, the spring unwinds without the seeds being embedded in the ground.

But that doesn’t mean giving up.

When the blade dries again and the spring dries, it automatically rewinds.

And wait for the next rainy day.

Without borrowing the power of animals or the wind,

Spread your own seeds

As if that weren’t enough, it comes with an automatic drill that allows it to plant itself into the ground.

A plant with seeds that turns on a switch at just the right time for rain to germinate.
