Making things smooth again with words about border flower (7,8)
I believe the answer is:
evening primrose
'flower' is the definition.
(I've seen this before)
'making things smooth again with words about border' is the wordplay.
I cannot really understand how this works, but
'smooth' could be 'even' (associated in meaning) and 'even' is located in the answer.
'border' could be 'rim' (both can mean an edge) and 'rim' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for evening primrose that I've seen before include "source of oil" , "Plant with pale yellow flowers" , "type of oil" , "Oenothera" , "Herbal remedy" .)
