Much like a cow but my hair is so thick, sometimes you'll do this if grossed out or sick

A two worded flower of worldly acclaim, the start of a day is half of my name.

I have a ear, but I do not have a pair ofeyes, yet i stalk. I am often seen in pieces, and sometimes whole.

I am surrounded by heat, but I do not have weight. You might find me in a desert.

Found abundantly in your river beds, You can work with me to no end, Throw me with love and watch me bend, to your vision then give it to your friend.
