Wild mule, for example, into garden plant (6)
I believe the answer is:
legume
'garden plant' is the definition.
'legume' can be an answer for 'plant' (type of plant). I am not certain of the 'garden' bit.
'wild mule for example into' is the wordplay.
'wild' indicates anagramming the letters.
'for example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'into' indicates putting letters inside.
'mule' with letters rearranged gives 'lume'.
'lume' placed around 'eg' is 'LEGUME'.
Can you help me to learn more?
(Other definitions for legume that I've seen before include "A fruit that bears its seed in pods" , "Glue me (anag) - climbing bean or pea plant" , "Bean, pea etc" , "Bean or pea, for example" , "pulse" .)
