Lear's daughter, stuck between ducks, leaves (7)
I believe the answer is:
oregano
'leaves' is the definition.
(leaves used as herbs)
'lear's daughter stuck between ducks' is the wordplay.
'lear's daughter' becomes 'regan' (one of King Lear's daughters).
'stuck between' indicates putting letters inside.
'ducks' becomes 'OO' (two O's - duck means zero in cricket).
'regan' placed into 'oo' is 'OREGANO'.
(Other definitions for oregano that I've seen before include "leaves for season" , "that's aromatic" , "Dried marjoram" , "Aromatic culinary herb" , "Type of herb" .)
