Willowleaf sunflower is a herbaceous perennial in the daisy family (Asteraceae) native to the central United States, primarily in the Great Plains and Ozark Plateau and is found growing over limestone soils in prairies and meadows. Genus name comes from the Greek words helios meaning sun and anthos meaning flower. Specific epithet means with leaves like willows ( Salix ). Willowleaf sunflower will grow 5 to 6 feet tall but can reach 8 feet in height with a 1 to 3-foot spread. It is tolerant of most soil conditions as long as they are well-drained and prefers full sun but will tolerate some shade. Shading causes the plant to grow taller and produce fewer blooms. The plant will spread by creeping rhizomes and seeds. Clumps can be divided every 2 to 4 years as needed. In late summer to fall, clusters of bright yellow ray petals surround a brown center of disc flowers that are attractive to pollinators. The attractive leaves are narrow, drooping and willow-like with soft hairs. Birds are attracted to the seeds that follow flowering. Native bees nest in the dead, hollow stems, so gardeners are encouraged to cut back dead stems to 12 to 24 inches and allow them to remain standing until they disintegrate on their own.

It can also be used in the back of the border, providing bright yellow color for the fall pollinator garden. Useful in a cutting or cottage garden. There are shorter cultivars for garden use. Insects, Diseases, and Other Plant Problems: Watch for rust, leaf fungal spots and powdery mildew. Watch for aphids, beetles and caterpillars.
