This could be blooming thing Cinderella lost? (5-7)
I believe the answer is:
ladys-slipper
'this could be blooming' is the definition.
(type of flowering plant)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for ladys-slipper that I've seen before include "Type of orchid" , "Wild orchid (for Cinderella?)" .)
