The hedge flower that will make an odd line (9)
I believe the answer is:
dandelion
'the hedge flower' is the definition.
'dandelion' can be an answer for 'flower' (thesaurus). I am unsure of the 'the hedge' bit.
'will make an odd line' is the wordplay.
'will make' indicates an anagram.
'an'+'odd'+'line'='anoddline'
'anoddline' is an anagram of 'DANDELION'.
'that' is the link.
Can you help me to learn more?
(Other definitions for dandelion that I've seen before include "Common yellow-flowered plant" , "Flower with a "clock"" , "I nod, laden with yellow flower" , "Common yellow-flowered weed" , "salad leaves" .)
