This is supposedly a byproduct of the nuclear power plant disaster, yeah?
‘cause that happened in 2011, whereas instances of this photo dating from 2008 onward can be found all over the internet. I’m pretty sure this is just your average, mutated flower. Why wouldn’t there be a whole field of mutant plants? This kind of stuff happens to flowers more than you’d think, and particularly to daisies. More mutant flowers here and explanations of what can cause this kind of abnormal growth!
But yeah once again tumblr is a haven of false ‘facts.’
You should look at the link to the other mutant flowers.
