Talking plant? Give over! (4)
I believe the answer is:
cede
'give over' is the definition.
(I've seen this in another clue)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for cede that I've seen before include "Transfer" , "Yield or give up to another" , "Give up rights or possession" , "Allow" , "Give up (eg, power)" .)
