Plant manufactured panel heaters (9,3)

I believe the answer is:

elephant's-ear

'plant' is the definition.
(elephant's ear is a kind of plant)

'manufactured panel heaters' is the wordplay.
'manufactured' indicates anagramming the letters.
'panel'+'heaters'='panelheaters'
'panelheaters' is an anagram of 'ELEPHANTS-EAR'.
