Jessica tries to befriend Pam Isley even though Babs tells Jess that Pam wants to be alone, and the rest of the team concurs. Jess insists on befriending her, with Pam rejecting her repeatedly. Eventually Pam finds out that Jess is protesting the cutting of an ancient tree. She joins her and they chain themselves to the tree. At night Pam tells the story of the tree who "speaks" to her by rustling in the wind. Pam grows angry over the imminent destruction of the tree. She clenches her fist in the soil, and vines grow around it. When the working crew arrives, Pam vanishes and Poison Ivy attacks the crew with her vines, flipping cars, tearing the road, and coiling the vines around the workers. She throws a bulldozer at the crew, and Green Lantern deflects it back, felling the ancient tree. Poison Ivy falls to her knees, in tears and a fit of rage. She retreats into the ground with her vines and tells Green Lantern that she will pay. The next scene, Pam and Jess find an acorn by the stump of the ancient tree. They plant it, and the episode ends with a shot of the acorn growing into a sapling as Jess and Pam walk away.
This episode showcases that while caring for plants and trees, Pamela would rather eat meat than vegan food. This was also touched upon in the short "Vegecide".
Aside from groans, Karen does not have any spoken dialogue in this episode.
The title of this episode may be a reference to the Shel Silverstein children's book The Giving Tree.
This is the fourth episode in which one or more of the main characters do not transform into heroes. The first was "Sweet Justice Part 1" (Babs, Karen, Kara, Jessica, Zee), the second was "She Might Be Giant" (Jessica and Zee, Leslie), the third was "Crushing It" (Diana).
