Wild flower around bottom of garden (7)
I believe the answer is:
violent
'wild' is the definition.
('violent' can be a synonym of 'wild')
'flower around bottom of garden' is the wordplay.
'flower' becomes 'violet' (I've seen this before).
'around' indicates putting letters inside.
'bottom of garden' becomes 'n' (I can't explain this - if you can you should give a lot more credence to this answer).
'violet' enclosing 'n' is 'VIOLENT'.
Can you help me to learn more?
(Other definitions for violent that I've seen before include "Extreme(ly aggressive)" , "Using much force" , "Vehement; unrestrained" , "Bloodthirsty" , "Sharp" .)
