Present a plant (5)
I believe the answer is:
hosta
'plant' is the definition.
The answer is an example.
'present a' is the wordplay.
'present' becomes 'host' (I've seen this before).
'host'+'a'='HOSTA'
(Other definitions for hosta that I've seen before include "Ornamental foliage plant; as hot (anag.)" , "flowering plant" , "Garden plant with ornamental foliage" , "Athos (anag) - perennial plant" , "leafy plant" .)
