Shrub put in particular island area (10)
I believe the answer is:
poinsettia
'shrub' is the definition.
(poinsettia is a kind of shrub)
'put in particular island area' is the wordplay.
'put' becomes 'set' (both can mean to place or position).
'in' is an insertion indicator.
'particular' becomes 'point' (synonyms).
'island area' becomes 'ia' (this might be a standard abbreviation which I don't know about).
'set' put into 'point' is 'poinsett'.
'poinsett'+'ia'='POINSETTIA'
Can you help me to learn more?
(Other definitions for poinsettia that I've seen before include "House plant, popular at Christmas -- tiniest OAP (anag)" , "poisonous bush" , "American plant" , "bloom" , "Ornamental house plant" .)
