Small growth in hernia's no bother after receding (6)
I believe the answer is:
bonsai
'small growth' is the definition.
(I've seen this before)
'in hernia's no bother after receding' is the wordplay.
'in' says the answer is hidden in the clue.
'receding' says the letters should be written in reverse.
'iasnob' can be found hidden inside 'hernias no bother after'.
'iasnob' backwards is 'BONSAI'.
(Other definitions for bonsai that I've seen before include "Very little tree" , "Dwarf trees and shrubs" , "stunted growth" , "Bosnia (anag.)" , "(Cultivation of) dwarf trees" .)
