Blessed to be flourishing (8)
I believe the answer is:
blooming
I believe this clue is a double definition.
'blessed' is the first definition.
(thesaurus)
'be flourishing' is the second definition.
(thesaurus)
'to' acts as a link.
(Other definitions for blooming that I've seen before include "Blossoming" , "Looking healthy" , "Healthy -- flowering" , "Euphemistic expletive - in flower" .)
