Places to which people retire may be full of flowers
I believe the answer is:
beds
'places' is the definition.
(bedding is a kind of placing)
'people retire may be full of flowers' is the wordplay.
I cannot quite understand how this works, but
'be' is within the answer.
This explanation may well be incorrect...
'to which' is the link.
Can you help me to learn more?
(Other definitions for beds that I've seen before include "Graduate teacher's" , "Garden plots - English county (abbr)" , "Dormitory items" , "Cots, bunks etc -- eastern English county (abbr)" , "Hospital places" .)
