Fragrant bloom and ubiquitous paint colour (8)
I believe the answer is:
magnolia
'fragrant bloom and ubiquitous paint colour' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for magnolia that I've seen before include "Creamy-white colour" , "Tree with solitary flowers" , "Creamy white, shrub" , "Mississippi, the ___ State - tree or shrub" , "Tinted white colour" .)
