Cup-bearer of the gods and a flowering shrub (4)
I believe the answer is:
hebe
'cup-bearer of the gods and a flowering shrub' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for hebe that I've seen before include "Cup-bearer of the gods and NZ plant" , "Youth personified" , "Cup-bearer of the gods and flowering shrub" , "Daughter of Zeus and Hera" , "Greek goddess of youth, wife of Hercules" .)
