As you may have guessed, the tulip tree (Liriodendron) gets its name because it produces blossoms that closely resemble springtime tulips. These buds are aromatic and are a golden-green hue ringed with vibrant orange. "The tulip tree, a member of the magnolia family, is one of the largest native trees in North America," says Walz. "Tulip trees are also the host plant for tiger and spicebush swallowtail butterflies."
