Tropical pear (7)
I believe the answer is:
avocado
'tropical pear' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for avocado that I've seen before include "Greenish-colour" , "Fruity colour" , "A dark green pear with cramy flesh" , "Pulpy fruit" , "Dull greenish colour" .)
