Iris used filler getting made up (5-2-3)

Ross

I believe the answer is:

fleur-de-lis

'iris' is the definition.
(I know that iris can be written as fleur-de-lis)

'used filler getting made up' is the wordplay.
'getting' says to put letters next to each other.
'made up' indicates anagramming the letters.
'used'+'filler'='usedfiller'
'usedfiller' anagrammed gives 'FLEUR-DE-LIS'.

I've seen this clue in The Telegraph.
