Got up and started smelling the flowers (5)
I believe the answer is:
roses
'the flowers' is the definition.
(I've seen this before)
'got up and started smelling' is the wordplay.
'got up' becomes 'rose' (I've seen this before).
'and' says to put letters next to each other.
'started' suggests taking the first letters.
The first letter of 'smelling' is 's'.
'rose'+'s'='ROSES'
(Other definitions for roses that I've seen before include "Bloomers" , "Flowers of 15th century war" , "Thorny shrubs with bright flowers" , "favours > certain wines" , "Occupants of bed" .)
