Herb's divine article (8)
I believe the answer is:
angelica
'herb's' is the definition.
(angelica is a kind of herb)
'divine article' is the wordplay.
'divine' becomes 'angelic' (I've seen this before).
'article' becomes 'a' (indefinite article).
'angelic'+'a'='ANGELICA'
(Other definitions for angelica that I've seen before include "Candied leaf-stalk" , "Candied part of herbs - nag Alice (anag)" , "Candied stem, decorates cake" , "may be sitting on top of the trifle" , "Candied stalks used for cake decoration" .)
