Helianthus nuttallii subsp. parishii
Parish's sunflower is a rare California native perennial that thrives in moist, partially shaded conditions such as wetland margins and riparian edges. Water regularly to keep the soil consistently moist, especially during dry summer months. It is best suited for wildlife gardens and native habitat restoration projects rather than typical home landscapes.
