Senor Saguaro is a tall cactus that is outside of Archie's home. It is described as a "30 foot giant that towered over the toolshed in the back of his [Archie's] home." The towering figure provides a talking companion to the rather unique professor, Archie. The cactus is a vivid reminder of the story taking place in Arizona, an area where definition and redefinition is set against the backdrop of fossilized remains. This is critical to the character of Stargirl, a vision of self definition, herself. Senor Saguaro standing outside of Professor Archibald Brubaker's home is also significant, for this is where the most amount of discussion and understanding happens for Leo in trying to understand the complexity of Stargirl and his emotions for her. Saturday morning classes are held at Brubaker's home, under the giant Senor Saguaro. The function of the cactus is more symbolic than anything else, and is a vivid reminder of how setting, in terms of Arizona and Archie's home, is powerful in the novel.
