A dryad (or wood nymph) is a female spirit often associated with a certain tree.


In Greek mythology, a dryad is usually a female spirit typically associated with a particular location or landform. Other nymphs, always in the shape of young maidens, were part of the retinue of a god, such as Dionysus, Hermes, or Pan, or a goddess, generally Artemis and Persephone. They are beautiful humanoids with elf-like appearance and can sometimes be seen with tree-like appendages and are sometimes green.

They live in groves, in trees and in valleys and cool grottoes. All dryads are born with a certain tree over which they will watch. A dryad either lives in a tree, in which case she is called a Hamadryad, or close to it. The life of dryad is connected with that of a tree. That is, the longer the tree lives, the longer the dryad does. If the death of a dryad is caused by a mortal, the gods will punish him/her. The dryad itself will punish any mortal who tries to hurt its tree. The nymphs at Camp Half-Blood act as waitresses at mealtimes.

Percy Jackson and the Olympians

The Lightning Thief

Luke summons a pit scorpion to kill Percy. When it gets Percy, Percy tries to get back to camp, but he is dying. Luckily, some wood nymphs carry him to the Big House. They are unnamed, but they did save his life.

The Titan's Curse

Grover and Percy watch a satyr chase a redheaded nymph until she goes into tree form and the satyr kisses her as she transforms herself into a tree. Grover sees this as perfectly normal.

Known Dryads

  • Juniper- Grover's girlfriend, a dryad, and lives in a Juniper tree. Grover is said to once have had a crush on a wood nymph that lived inside a blueberry bush. There have been references to her having green tears appearing similar to or the same as the chlorophyll present in plants. Juniper also appears to have the ability to disappear in a puff of green mist, and it is unclear whether this ability is present in all wood nymphs.
