Right before entering Hades' Palace you have to go through Persephone's Garden.
Hades' Palace
( http://camphalfblood.wikia.com/wiki/Persephone's_Garden )
The Garden is extremely unnatural and strange since there are multi-colored mushrooms, poisonous scrubs, and weird luminous plants that grew without sunlight. There were also precious jewels that seemed to compensate the lack of flowers, such as clumps of raw diamonds and piles of rubies as big as his fist. Last but not least, there were Medusa's garden statues of petrified children, satyrs, and centaurs, standing here and there and all smiling grotesquely.
In the center of the garden was an orchard of pomegranate trees, their orange blossoms neon bright in the dark, and the fruit had an overwhelmingly sweet tart smell.
You must go through here first before entering Hades' Palace.
