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'.
Though, I am not sure 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" .)
