Corrected her label for the flowering plant (8)
I believe the answer is:
harebell
'the flowering plant' is the definition.
'harebell' can be an answer for 'plant' (harebell is a kind of plant). I am not sure about the 'the flowering' bit.
'corrected her label' is the wordplay.
'corrected' indicates anagramming the letters.
'her'+'label'='herlabel'
'herlabel' anagrammed gives 'HAREBELL'.
'for' is the link.
Can you help me to learn more?
(Other definitions for harebell that I've seen before include "One to blossom" , "Pale blue flower in beer hall, oddly" , "Wild hyacinth" , "Minor bloomer" , "Delicate blue campanula" .)
