These "Mutant Daisies" Near Japan's Nuclear Disaster Site Are Freaking Everyone Out

The weird-looking flowers were snapped by a Twitter user near the Fukushima Daiichi site.

There was a frenzy on Thursday after a Twitter post surfaced claiming to show pictures of "mutant daisies" near the site of Japan's 2011 nuclear disaster.

マーガレットの帯化(那須塩原市5/26)② 右は4つの花茎が帯状に繋がったまま成長し,途中で2つに別れて2つの花がつながって咲いた。左は4つの花茎がそのまま成長して繋がって花が咲き輪の様になった。空間線量0.5μSv地点(地上高1m)

The photos were posted by user @San_kaido in May and June, but just began to get attention this week.

@rayon_violet 他の写真もお送りします。アブ(?)との比較で大体検討がつくかと思います。花は直径7~8cmぐらいになります。

The Twitter account belongs to a person who frequently posts pictures showing what they believe to be effects from the meltdown of the Fukushima Daiichi nuclear plant in 2011.


In another post, the user said they believe the cause of the flowers' deformation is "likely to be radioactive." The user also shares other plants that seem to be deformed.

近所(那須塩原市)のお宅のマーガレットの帯化と言う現象 4つの花茎が横に繋がったまま成長し,左の茎は途中で2つに別れ,右は4つがそのまま帯状に繋がった花になります。 一種の奇形ですが空間線量0.5μSv地点と言うのが気になっています。

As soon as the photos began to go viral, many people began to proclaim that the daisies are clear evidence of radiation mutation in the area.

4 years after Japan’s Fukushima nuclear plant disaster, weird things are happening nearby , like this mutant daisy

And they are "terrified."

#yikes #whenwillwelearn #fukushimadaisy I'm #terrified to see what else will be deformed. .

Of course, someone had to make a "mutant daisy" Twitter account.

My petals yearn for human blood. #fukushima #daisy

Well, that's not so clear.

The daisies' weird shape is likely due to a condition called "fasciation."

The condition can affect many different types of flowers and plants, according to the University of California.

There are several different reasons why a plant could develop the mutation.

The causes include a bacteria infection, a viral infection, or a genetic mutation, according to Iowa State University.

Another cause of fasciation is "damage to the plants by frost, animals (including insects), chemical or mechanical injury," according to the Royal Horticultural Society.

This "damage" can be as innocuous as a gardening hoe hitting the plant while it is growing.

So, is this case of fasciation a result of radiation poisoning? Maybe, but it is likely due to a myriad of other causes.

No matter what the cause is, the condition doesn't affect the health of the plant and can't be spread to other plants.

"Just because a particular plant exhibited fasciation one season does not necessarily mean it will again in the future," according to Purdue University. "In most cases, fasciation is just a random oddity."
