Man I see ordering a flower (7)
I believe the answer is:
nemesia
'a flower' is the definition.
(I've seen this before)
'man i see ordering' is the wordplay.
'ordering' indicates anagramming the letters.
'man'+'i'+'see'='manisee'
'manisee' is an anagram of 'NEMESIA'.
(Other definitions for nemesia that I've seen before include "I am seen (anag) - flower" , "Plant with colourful funnel-shaped flowers" , "Meanies (anag) - flower" , "Colourful 13 across" , "Funnel-shaped flower" .)
