I'd say it wrongly making a bloomer (5)
I believe the answer is:
daisy
'a bloomer' is the definition.
(I know that daisy is a type of bloomer)
'i'd say it wrongly' is the wordplay.
'i'd say' anagrams to 'DAISY'.
However, I'm unsure how the anagram is indicated.
'making' is the link.
Can you help me to learn more?
(Other definitions for daisy that I've seen before include "chain, just the smallest bit?" , "girl" , "Lawn flower, weed" , "Grassland flower" , "Old song: '. . . . ., . . . . . give me your answer, do'" .)
