Delicate flower arranged in church by French designer (6)
I believe the answer is:
orchid
'delicate flower' is the definition.
'orchid' can be an answer for 'flower' (orchid is a kind of flower). I am not certain of the 'delicate' bit.
'arranged in church by french designer' is the wordplay.
I cannot really understand how this works, but
'church' could be 'rc' (abbreviation for Roman Catholic) and 'rc' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for orchid that I've seen before include "Highly prized flower" , "Showy tropical flower" , "Common houseplant" , "Glamorous tropical flower" , "Exotic flower with bee and lady varieties" .)
