Bloom shows full desire uncontrollably (5-2-3)

I believe the answer is:

fleur-de-lis

'bloom' is the definition.
(flowers bloom)

'full desire uncontrollably' is the wordplay.
'uncontrollably' is an anagram indicator (I've seen this in other clues).
'full'+'desire'='fulldesire'
'fulldesire' with letters rearranged gives 'FLEUR-DE-LIS'.

'shows' is the link.

I've seen this clue in The Telegraph.
