Bush's history edited in note (9)
I believe the answer is:
forsythia
'bush's' is the definition.
(forsythia is a kind of bush)
'history edited in note' is the wordplay.
'edited' indicates anagramming the letters.
'in' means one lot of letters goes inside another.
'note' becomes 'fa' (fourth note in sol-fa notation: doh, ray, me...).
'history' anagrammed gives 'orsythi'.
'orsythi' placed into 'fa' is 'FORSYTHIA'.
(Other definitions for forsythia that I've seen before include "bloomer in spring" , "A frosty hi to the flowering shrub" , "Floral shrub" , "Bush" , "Garden plant" .)
