Wolf's tooth is a term used in botany to describe a type of creeping plant that has sharp teeth on its stem. The plant is also known as the scalloped-edged creeper, due to the serrated teeth that resemble the fangs of a wolf. Other synonyms for wolf's tooth include creeping jenny, moneywort, and Lysimachia nummularia. The plant is often used as a ground cover due to its ability to spread quickly and form a dense mat. It is also commonly used in rock gardens and as a border plant. Regardless of its name, wolf's tooth remains a popular choice for gardeners looking to add a touch of greenery to their outdoor spaces.
