Care about tree (4)

Ross

I believe the answer is:

'tree' is the definition.
(I've seen this before)

'care about' is the wordplay.
'about' indicates an anagram.
'care' anagrammed gives 'ACER'.

(Other definitions for acer that I've seen before include "Plant", "Tree of maple family", "ornamental tree", "Tree or shrub of the maple genus", "Care about the maple?".)

I've seen this clue in Mirror.
