Heavenly, a cake decoration (8)

I believe the answer is:

angelica

'cake decoration' is the definition.
(angelica stalks are used to decorate cakes)

'heavenly a' is the wordplay.
'heavenly' becomes 'angelic' (relating to angels or heaven).
'angelic'+'a'='ANGELICA'

(Other definitions for angelica that I've seen before include "Its candied leaves are used in cake decoration" , "may be sitting on top of the trifle" , "Candied stalks used for cake decoration" , "Decorative candied stalk" , "Candied leaf-stalks, used to decorate cakes" .)

I've seen this clue in The Times and The Telegraph.
