A plant that yields for the fall (7)
I believe the answer is:
cropper
'for the fall' is the definition.
(I have seen 'Heavy fall' mean 'cropper' so perhaps 'fall' could also mean 'cropper')
'a plant that' is the wordplay.
I cannot quite understand how this works, but
'a' could be 'per' (eg 'one a day' means 'one per day') and 'per' is present in the answer.
The remaining letters 'crop' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'yields' acts as a link.
Can you help me to learn more?
(Other definitions for cropper that I've seen before include "Come a --, suffer disaster" , "failure" , "Heavy fall" , "Disastrous mistake or fall" .)
