Merremia peltata, commonly known as the yellow wood rose or Noyau vine, is a flowering vine belonging to the Convolvulaceae family. Native to tropical regions, this vine is known for its attractive yellow flowers and is found in a variety of habitats, including forests, disturbed areas, and along roadsides. While appreciated for its ornamental value, it's important to note that in certain regions, Merremia peltata is considered an invasive species.
