Tears flowing for flower? (5)
I believe the answer is:
'for flower?' is the definition.
(type of flower)
'tears flowing' is the wordplay.
'flowing' is an anagram indicator.
'tears' anagrammed gives 'ASTER'.
(Other definitions for aster that I've seen before include "(Starlike) flower" , "Large daisy" , "bloomer" , "Plant like a Michaelmas daisy" , "Kind of daisy" .)
