Hardy perennial, this? Yes and no (6)
I believe the answer is:
laurel
This might be a double definition.
'hardy perennial' is the first 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 don't see?
'this? yes and no' is the second definition.
The definition suggests a singular noun which matches the answer.
Can you help me to learn more?
(Other definitions for laurel that I've seen before include "Stan possibly" , "girl" , "Evergreen shrub" , "literary award" , "one half of double act" .)
