The genus Inula comprises 100 to 200 species of annuals and perennials from Europe, Asia and Africa. Only a few species have outstanding ornamental properties.
Most species are hairy and coarse, and bear alternate leaves.
These plants are easily grown providing they are in full sun, and planted in a moist, well-drained soil, although most will tolerate somewhat wetter, even boggy conditions. I have grown Inula helenium for many years. It is native to Europe, and northern Asia, and has been naturalized in eastern North America. The basal leaves are large so give these plants room to spread, and look their best. Plant about 90 cm from other plants.
