Demeter

Demeter is the goddess of the Earth and Harvest.

Appearance
She is a dark-haired goddess and wears green robes. Her throne is woven out of apple-tree branches. She mirrors Gaea, the Titan Earth Goddess, and nature is her sphere of power. She can make plants grow and flourish, but can also make the world cold and kill all plants, which she does during the fall and winter, since Hades kidnapped her daughter. Her daughter has to stay in the Underworld for half of the year, and then Demeter is depressed, so the joy in which she keeps the earth alive is lost, resulting in the 'death' of plants (since they don't really die, since the plants bloom again in spring).

History
She is most notable for her daughter, Persephone's kidnapping by her older brother, Hades. Demeter was devastated, and mourns for her daughter during the fall and winter months, when Persephone must stay in the Underworld.

The Series
She has no major demigod children that have been identified, but does have a cabin at Camp Half-Blood. Her cabin is said to have a roof made of grass and her kids have the ability to make any kind of plants grow on the windowsill. She first appeared in The Titan's Curse at the winter solstice council meeting, having no known speaking role but one of the first few, along with Aphrodite, to vouch for Percy Jackson's safety. She and Persephone make appearances in The Last Olympian in the Underworld. As a guest in Hades's realm due to her daughter's presence, she nags Persephone about marrying her brother, Hades, displaying a character similar to that of elderly mothers in modern Western pop culture, and meets Percy and Nico when they go down for the Styx, this time curiously displaying no particular affection for either. Her most famous child is Katie Gardner lead counselor for her cabin. After Nico convinces Hades to reinforce Olympus at a desperate moment, both Demeter and her first daughter joined with him, turning an entire army of giants into a wheat field while in battle and later joining the other gods on Olympus when they reward the heroes.
