Flower that may create autumn riots, nothing less (10)
I believe the answer is:
nasturtium
'flower that' is the definition.
The definition and answer can be both plants as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'create autumn riots nothing less' is the wordplay.
'create' indicates an anagram.
'nothing' becomes 'o' (looks like zero - 0).
'less' is a deletion indicator.
'autumn'+'riots'='autumnriots'
'autumnriots' with 'o' taken away is 'autumnrits'.
'autumnrits' with letters rearranged gives 'NASTURTIUM'.
'may' acts as a link.
Can you help me to learn more?
(Other definitions for nasturtium that I've seen before include "Garden climber" , "flowering plant" , "Common trailing plant" , "bloomer" , "ITMA's U-turn (anag) - flower" .)
