Dishes with shape of petals (6)
I believe the answer is:
plates
'dishes' is the definition.
(I know this)
'shape of petals' is the wordplay.
'shape of' is an anagram indicator (I've seen 'shapes' mean this (shape can mean to mould or transform)).
'petals' with letters rearranged gives 'PLATES'.
'with' is the link.
(Other definitions for plates that I've seen before include "Strange staple for crockery items" , "Shallow dishes" , "Eating utensils of staple kind" , "They're on the table" , "dentures" .)
