Tasty plant (9)
I believe the answer is:
succulent
I believe this is a double definition.
'tasty' is the first definition.
(thesaurus)
'plant' is the second definition.
(succulent is a kind of plant)
(Other definitions for succulent that I've seen before include "One may be potted!" , "Juicy" , "Full of juice" , "Eg, a cactus" , "Luscious" .)
