Haphazardly rip up root miscellany (9)
I believe the answer is:
potpourri
'miscellany' is the definition.
(I know that miscellany can be written as potpourri)
'haphazardly rip up root' is the wordplay.
'haphazardly' indicates anagramming the letters.
'rip'+'up'+'root'='ripuproot'
'ripuproot' with letters rearranged gives 'POTPOURRI'.
(Other definitions for potpourri that I've seen before include "Hotchpotch" , "Petals and spices to perfume a room" , "Selection" , "Mixture of dried, scented items" , "collection with pleasant bouquet" .)
