Handy plant? (4)
I believe the answer is:
palm
'handy plant?' is the definition.
The answer and definition can be both plants as well as being singular nouns.
Maybe you can see a link between them that I can't see?
This is all the clue.
Can you help me to learn more?
(Other definitions for palm that I've seen before include "Evergreen tree and part of the hand" , "Inner surface of the hand" , "Symbol of victory" , "Date-tree" , "Conceal in the hand" .)
