Thin coverings of strewn petals (6)
I believe the answer is:
plates
'thin coverings' is the definition.
'plates' can be an answer for 'coverings' (plate is a kind of covering). I am unsure of the 'thin' bit.
'strewn petals' is the wordplay.
'strewn' indicates an anagram.
'petals' with letters rearranged gives 'PLATES'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for plates that I've seen before include "Shallow dishes" , "Flat dishes" , "Eating utensils of staple kind" , "They're on the table" , "dentures" .)
