Flowery Poetry

I saw a lady employee pick flowers in the landscaped footpath on the way to office in the morning, presumably to adorn her hair, and I was thinking of arguments in a self-righteous tone on "how its not appropriate to pluck flowers in public places". 

Thats when this lyric by Vairamuthu came to my mind -

Pudhu Vellai Mazhai song- from the movie Roja. The duet has blue-highlighted lines by the male singer, and white lines by female singer. 

So do all flowers bloom and is most poetry ever written - for the same reason?
