A bit of a bloomer from friend in the Home Counties (5)
I believe the answer is:
sepal
This clue might be a double definition.
'a bit of a bloomer' is the first definition.
(I've seen this before)
'friend in the home counties' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for sepal that I've seen before include "part of leaf" , "Part of a flower's outer envelope" , "Part of a flower casing" , "Calyx segment" , "Violet" .)
