End of April, I say you snip back the flowers (6)

'flowers' is the definition.
The answer and definition can be both plants as well as being plural nouns.
Maybe they are linked in a way I don't understand?

'end of april i say you snip back' is the wordplay.
'end of' indicates one should take the final letters.
'i say you' becomes 'u' (I am not sure about this - if you are sure you should believe this answer much more).
'back' shows that the letters should be reversed in order.
The last letter of 'april' is 'l'.
'snip' written backwards gives 'pins'.
'l'+'u'+'pins'='LUPINS'

'the' is the link.

Can you help me to learn more?
