Ultimately celery has plastic Lidl wrapping that depicts simple rural scene (5)
I believe the answer is:
idyll
'rural scene' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for idyll that I've seen before include "Perfect rustic scene" , "Poem descriptive of pastoral life" , "Picturesque pastoral scene" , "Blissful situation" , "Perfect situation" .)
