List of plants kept by Carol finally turned up (5)
I believe the answer is:
flora
'list of plants' is the definition.
(I've seen this before)
'kept by carol finally turned up' is the wordplay.
'kept by' says the answer is hidden in the clue.
'turned up' says the letters should be written backwards.
'arolf' can be found hidden inside 'carol finally'.
'arolf' backwards is 'FLORA'.
(Other definitions for flora that I've seen before include "Plants of a region or age" , "Botanical specimens" , "Plants of a particular region" , "growing flowers" , "Lots of plants" .)
