Like father, she has her day (5)
I believe the answer is:
poppy
'like father she' is the definition.
'Poppy' can be an answer for 'she'. I am not certain of the 'like father' bit.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for poppy that I've seen before include "Girl's name -- scarlet flower" , "Remembrance Day flower" , "Flower of cornfields" , "Wild flower having its day in November" , "Red field flower" .)
