A big nose found wild flowers (8)
I believe the answer is:
begonias
'flowers' is the definition.
(begonia is a kind of flower)
'a big nose found wild' is the wordplay.
'a big nose' anagrams to 'BEGONIAS'.
However, I'm unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for begonias that I've seen before include "Nosebag I put on for the flowers" , "O begin as flowers" .)
