Culture

Easily grown in average, medium, well-drained soil in full sun. Tolerant of wide range of soil conditions. If grown in part shade, plants tend to be taller and more open, produce fewer flowers and require support. Spreads over time by creeping rhizomes to form dense colonies. Divide every 3-4 years to control spread and maintain vigor.

Noteworthy Characteristics

Willow-leaved sunflower is a Missouri native plant that occurs in unglaciated western Missouri prairie areas south of the Missouri River. Features clusters (branched panicles) of 2-2.5" wide sunflowers with bright yellow rays and dark brown center disks atop rigid, whitish-green stems typically growing 5-6' (less frequently to 8') tall. Narrow, drooping, willow-like, pale green leaves (5-7"). Blooms from late summer to fall. Good fresh cut flower.

Problems

No serious insect or disease problems. Taller plants may need staking.

Garden Uses

Attractive foliage and profuse late summer to fall bloom make this an excellent addition to the border background, wild or native plant garden, or naturalized planting.
