Entertainer needing a plant (5)
I believe the answer is:
hosta
'plant' is the definition.
The answer is an example.
'entertainer needing a' is the wordplay.
'entertainer' becomes 'host' (host is a kind of entertainer**).
'needing' is a charade indicator (letters next to each other).
'host'+'a'='HOSTA'
(Other definitions for hosta that I've seen before include "leafy plant" , "Athos (anag) - perennial plant" , "Plant that likes shade" , "Garden plant prized for its foliage" , "flowering plant" .)
