In Greek mythology, who was Persephone's mother?

In Greek mythology, Persephone’s mother was Demeter.

Demeter was the goddess of agriculture, grain, and fertility of the earth. Persephone was her daughter, and the central myth of their separation explains the seasonal cycle. Hades abducted Persephone and took her to the Underworld. Demeter’s grief caused crops to fail and the earth to become barren.

A compromise was eventually reached. Because Persephone had eaten pomegranate seeds in the Underworld, she could not remain permanently with Demeter. She would spend part of the year with Hades and part with her mother. When Persephone returns, Demeter allows the earth to flourish; when Persephone descends again, the land becomes less productive.

The exact length of Persephone’s stay varies among ancient accounts. The myth is preserved especially in the Homeric Hymn to Demeter, which also explains the Eleusinian Mysteries, an important religious festival. Persephone is therefore both a goddess linked with spring growth and a queen of the Underworld.
