I come everyday when the sun decent it daily way people will go home when I'm about start my stroll

I’m a unicorn that forgot the magic and chose violence instead.

I bloom when rain clouds cry, but offer shade beneath the sky. What am I?

I grow like little puffs of white, then turn to cloth both soft and light. Against your skin I’m often worn, a cozy friend from plant life born.

If planted in the ground, flowers spring from me. But when activated in the air, only light blooms from me.
