Heavenly bouquet here, alluring to some extent (8)
I believe the answer is:
ethereal
'heavenly' is the definition.
('ethereal' can be similar in meaning to 'heavenly')
'bouquet here alluring to some extent' is the wordplay.
'to some extent' indicates a hidden word.
'ETHEREAL' can be found hidden inside 'bouquet here alluring'.
(Other definitions for ethereal that I've seen before include "Take ale there: it's light and delicate" , "Delicate and perfect" , "Warm approval" , "Light and delicate in appearance, heavenly" , "Airy, celestial" .)
