Woolly sunflowers is an annual or perennial shrub or subshrub, some species growing to a height of 2 m. Leaves present generally alternate and entire to nearly compound, with woolly hairs on some of the species. The inflorescence contains numerous yellow flower heads in flat-topped clusters. Fruits are angled in the outer flowers, but are generally club-shaped for the inner flowers; the pappus is somewhat jagged. The genus is native to western North America, with a concentration of narrow endemics in woolly sunflowers.
Water:
Woolly sunflowers prefers environments resembling its native habitat, requiring consistent weekly watering to thrive. While moderately drought-tolerant, it benefits from natural rainfall, needing supplemental water during dry spells, particularly during its active growing season to support foliage and flowering.
Propagation:
Propagation methods for woolly sunflowers include seed sowing, cuttings, and division, requiring proper light, temperature, and well-draining soil. Mimicking native habitat conditions is crucial. Collect seeds post-bloom, use rooting hormone for cuttings, and divide established clumps in spring for successful growth.
