Upset if such a bloomer is revealed (7)
I believe the answer is:
fuchsia
'bloomer is revealed' is the definition.
I can't judge whether this definition defines the answer.
'upset if such a' is the wordplay.
'upset' indicates anagramming the letters.
'if'+'such'='ifsuch'
'ifsuch' with letters rearranged gives 'fuchsi'.
'fuchsi'+'a'='FUCHSIA'
Can you help me to learn more?
(Other definitions for fuchsia that I've seen before include "If such a thing could be a wild flower" , "Flower; colour" , "If such a plant is a showy flower" , "Vivid purplish-red" , "Colourful flower, if such a mix is possible" .)
