flowers on the roadside

this is the kind of wildflowers that grow on the roadside and shrubs, at first glance we see is normal and there is no beauty in the flower but at the time was blooming like this then the new beauty we can enjoy. before the bloom petals are yellow but after blossoming flowers are white like cotton. this flower can break away from its petals when it is almost old and the white feathers will fly along with the seeds which then the body becomes big and eventually become a tree or weeds.

how to mow the weeds with a spore system that releases seeds from the petals, but the seeds fly with small feathers attached to the seeds. the little feathers are like parachutes to fly and find new places to grow.
