👉 Nasturtiums are a type of flowering plant that is native to Europe and Asia. They are commonly known as "nasty" because they have a strong, sour, or unpleasant taste. The specific variety of nasturtium is not widely recognized by all species, but the general classification is based on its color, size, and shape. Nasturials are often used in culinary dishes, such as in stews, soups, and sauces.
