Flower plucked from porch I demolished (6)
I believe the answer is:
orchid
'flower' is the definition.
(I know that orchid is a type of flower)
'plucked from porch i demolished' is the wordplay.
'plucked from' says the answer is hidden in the clue.
'ORCHID' is hidden within 'porch i demolished'.
(Other definitions for orchid that I've seen before include "Plant with complex blooms" , "Blooming" , "elaborate bloomer" , "Showy tropical flower" , "Much sought-after family of plants" .)
