Flowers from the lady at the rest centre (6)
I believe the answer is:
irises
'flowers' is the definition.
(type of flower)
'lady at the rest centre' is the wordplay.
'lady' becomes 'Iris' (woman's name).
'at' is a charade indicator (letters next to each other).
'the rest centre' becomes 'es' (I can't justify this - if you can you should believe this answer much more).
'iris'+'es'='IRISES'
'from the' acts as a link.
Can you help me to learn more?
(Other definitions for irises that I've seen before include "Flowers found in the eye" , "Parts of eyes or flowering plants" , "Expensive painting" , "Flowers and parts of eyes" , "Flags" .)
