Inula is a large genus of about 90 species of flowering plants in the family Asteraceae, native to Europe, Asia and Africa. They may be annuals, herbaceous perennials or subshrubs that vary greatly in size, from small species a few centimeters tall to enormous perennials over 3 m (10 ft) tall. They carry yellow daisy-like composite flowerheads often with narrow ray-florets. Some common characteristics include pappus with bristles, flat capitulum, and lack of chaff.
