History and Comments: Butter and Eggs Snapdragon is native to Europe, and it is now considered a weed. It often grows in dense stands, and because it has creeping roots, it can take over areas, where it is not controlled. Several states list Butter and Eggs as an invasive weed. Butter and Eggs is also commonly referred to as Yellow Toadflax. It is called butter and eggs, because of the similarity of its flower colors to those products, and toadflax, because the orange spot resembles a toad's mouth and its leaves are similar to those of the flax plant.
