The velvety sunflower is a rare Florida-endemic subspecies of the beach sunflower, well-adapted to sandy, well-drained soils in warm, humid climates. It performs best in part shade to full sun with regular watering, though it benefits from good drainage to prevent root issues. A great choice for Florida native plant gardens, it attracts bees and butterflies with its cheerful yellow blooms.
