Ashy sunflower
Ashy sunflower (Helianthus mollis) carries soft, silvery-gray foliage and bright yellow heads from July into September. It colonizes by short rhizomes, forming patches that pump out pollen for bees and seed for goldfinches and quail.
Why landowners plant ashy sunflower
- Long bloom window bridges mid- and late-summer nectar gaps.
- Heavy pollen producer supporting specialist sunflower bees.
- Seed feeds songbirds and quail into fall.
- Very drought-tolerant on thin, droughty upland ground.
Site fit
Dry to dry-mesic uplands, roadside prairie, and thin rocky soils. Rhizomatous spread means it can dominate rich mesic sites — keep the rate low on fertile ground.
Establishment
Cold-moist stratification required; dormant seed. Establishes faster than most prairie forbs, often blooming in year two. Spreads outward from year three on.
Management
Fire-tolerant and stimulated by burning. Where spread is a concern, use spot mowing rather than herbicide to keep it in balance.
CRP practice fit
Mid- and late-summer bloomer for dry pollinator mixes.
Diversity forb on droughty upland CRP acres.

Frequently asked questions
It can spread by rhizome on rich, moist ground. Keep the rate at or below 0.1 PLS pounds per acre on fertile mesic sites; on droughty uplands it stays well behaved.
Goldfinches, native sparrows, and bobwhite quail work the seed heads from late summer into fall.
