Taffy taking a bit of a siesta in the garden (7)
I believe the answer is:
daisies
I'm afraid I can't explain this answer.
Can you help me to learn more?
(Other definitions for daisies that I've seen before include "Flowers with yellow centres" , "Asides I make to the flowers" , "Asides I use to describe flowers" , "Asides I address to the flowers" , "Pushing up the --" .)
