More than one sheep gathering offspring wild garlic (7)
I believe the answer is:
ramsons
'wild garlic' is the definition.
(synonyms)
'more than one sheep gathering offspring' is the wordplay.
'more than one sheep' becomes 'rams' (rams are adult male sheep).
'gathering' is an insertion indicator (gather can mean to acquire or bring in).
'offspring' becomes 'son' (male offspring).
'rams' placed around 'son' is 'RAMSONS'.
(Other definitions for ramsons that I've seen before include "Relish" , "Garlic" .)
