Helianthus nuttallii
Nuttall's sunflower is a hardy native perennial that thrives in moist to average soils with partial shade to full sun. Water regularly during the growing season and allow the soil surface to dry slightly between waterings. It spreads by rhizomes over time, so give it room to naturalize and divide clumps every few years to manage spread.
