Exotic blooming country is hot (10)
I believe the answer is:
outlandish
'exotic' is the definition.
(I've seen this before)
'blooming country is hot' is the wordplay.
'blooming' becomes 'out' (plants which have bloomed are 'out').
'country' becomes 'land' (synonyms).
'hot' becomes 'h' (abbreviation, eg on taps).
'out'+'land'+'is'+'h'='OUTLANDISH'
(Other definitions for outlandish that I've seen before include "Bizarre - hound's tail (anag)" , "Lad shoutin' (anag)" , "Exotic" .)
