Lanie is delighted that her aunt has returned and her wild garden is taking off—but her next door neighbor is not happy that Lanie is growing a "weed garden" right in their suburban neighborhood, next to her prize roses. She threatens to report Lanie and her family to the neighborhood association for violating the landscaping rules. Meanwhile, Lanie is horrified that the neighbor is using poison sprays in her garden, right next to where Lanie is trying to attract butterflies. Lanie wants to spread the word in her community about the benefits of natural gardening and nontoxic pest control, but when an opportunity arises, she falls short. Discouraged at first, Lanie finds another way, as she and her friends plan a garden festival at the Community Garden where she's been volunteering. On the day of the festival, Lanie and her neighbor find common ground—and a creative solution to their garden problem.
