Fruit is unusual archery motto (6,6)
I believe the answer is:
cherry tomato
'fruit' is the definition.
The definition and answer can be both plants as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'unusual archery motto' is the wordplay.
'unusual' is an anagram indicator.
'archery'+'motto'='archerymotto'
'archerymotto' anagrammed gives 'CHERRY TOMATO'.
'is' is the link.
Can you help me to learn more?
(Another definition for cherry tomato that I've seen is " Small red fruit".)
