Of blossoms (6)
I believe the answer is:
floral
'of blossoms' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for floral that I've seen before include "To do with flowers, flowery" , "could it be to do with naked ladies?" , "annuals?" , "Blooming" , "Of flowers, like wreath" .)
