Country agents to seize wandering Bloom (8)
I believe the answer is:
colombia
'country' is the definition.
(Colombia is an example)
'agents to seize wandering bloom' is the wordplay.
'agents' becomes 'cia'.
'to seize' is an insertion indicator.
'wandering' indicates an anagram.
'bloom' with letters rearranged gives 'olomb'.
'cia' going around 'olomb' is 'COLOMBIA'.
(Other definitions for colombia that I've seen before include "Bogota is its capital" , "Bogot++ is its capital" , "S American state" , "South American Republic" , "Coffee-exporting South American country" .)
