Daughter of Hera and Zeus (4)
I believe the answer is:
'daughter of hera and zeus' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for hebe that I've seen before include "Greek goddess of youth, wife of Hercules" , "Olympian cupbearer - evergreen garden shrub" , "Greek goddess of spring" , "Herculean bride" , "Zeus's daughter; shrub" .)
