Wrecked trees to be found in buttonhole (7)
I believe the answer is:
rosette
'found in buttonhole' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'wrecked trees to' is the wordplay.
'wrecked' indicates anagramming the letters.
'trees'+'to'='treesto'
'treesto' with letters rearranged gives 'ROSETTE'.
'be' acts as a link.
Can you help me to learn more?
(Other definitions for rosette that I've seen before include "Mark of affiliation" , "Prize; favour" , "Badge of office or honour" , "Ribbony badge" , "Colours" .)
