Plant, peanut I gathered (7)
I believe the answer is:
petunia
'plant' is the definition.
The answer is an example.
'peanut i gathered' is the wordplay.
'gathered' indicates anagramming the letters.
'peanut'+'i'='peanuti'
'peanuti' anagrammed gives 'PETUNIA'.
(Other definitions for petunia that I've seen before include "Flower - tuna pie (anag)" , "Common garden plant" , "Bloomer" , "Common garden 13 across" , "Garden plant, originally from S. America" .)
