Bedding plant found by old boy with priest in filming location (7)
I believe the answer is:
lobelia
'bedding plant' is the definition.
'lobelia' can be an answer for 'plant' (lobelia is a kind of plant). I am not certain of the 'bedding' bit.
'old boy with priest in filming location' is the wordplay.
'old boy' becomes 'OB' (abbreviation for a private school 'old boy').
'with' says to put letters next to each other.
'priest' becomes 'eli' (biblical figure).
'in' means one lot of letters goes inside another.
'filming location' becomes 'la' (I can't explain this - if you can you should believe this answer much more).
'ob'+'eli'='obeli'
'obeli' inserted into 'la' is 'LOBELIA'.
'found by' is the link.
Can you help me to learn more?
(Other definitions for lobelia that I've seen before include "Flower used for hanging baskets" , "Popular bedding plant" , "found in bed" , "Boil ale to get the flower" , "Common garden plant; oil bale (anag.)" .)
