Flower you initially left pressed in paper (3-4)

'flower you initially' is the definition.
I can't judge whether this definition defines the answer.

'left pressed in paper' is the wordplay.
'left' shows that the letters should be reversed in order.
'pressed' becomes 'ly' (I can't explain this - if you can you should believe this answer much more).
'in' is an insertion indicator.
'paper' becomes 'daily' (a daily is a kind of newspaper).
'ly' backwards is 'yl'.
'yl' inserted inside 'daily' is 'DAY-LILY'.

Can you help me to learn more?
