Flowers pushed up when late (7)
I believe the answer is:
daisies
'flowers' is the definition.
(daisy is a kind of flower)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for daisies that I've seen before include "Sis, idea about the little flowers" , "Flowers with yellow centres" , "Pushing up the --" , "Asides I use to describe flowers" , "Asides I address to the flowers" .)
