As white as a cloud.
As light as the air.
I float on the breezes,
without a care.

I'll tickle your nose,
and make you sneeze.
Especially if you
have allergies.

I show up in spring
and stay 'til fall.
I'm the curse of gardeners,
banned by all.

Wherever I land
I set up my home.
Put down my roots
in the rich loam.

My flower is yellow
and looks like the sun.
When bloom time is over,
a white ball I become.

Kids grab my stem
and give a blow.
Poof in the air,
looking like snow.

What am I??
Give it a guess.
If you said dandelion,
I'll have to say yes.
