Scare about ram running amok in plant (8)
I believe the answer is:
shamrock
'plant' is the definition.
(I know that shamrock is a type of clover)
'scare about ram running amok' is the wordplay.
'scare' becomes 'shock'.
'about' indicates putting letters inside.
'running amok' indicates an anagram.
'ram' anagrammed gives 'amr'.
'shock' enclosing 'amr' is 'SHAMROCK'.
'in' is the link.
(Other definitions for shamrock that I've seen before include "Symbol of Ireland" , "Clover native to Ireland" , "Sign of first part of 10 [IRISH [SEA]]" , "Clover leaf" , "Clover-like plant" .)
