Helianthus debilis subsp. debilis
Helianthus debilis subsp. debilis
The beach sunflower is a Florida-native perennial groundcover known for its bright yellow flowers and exceptional tolerance of sandy, coastal soils. It performs best in partly shaded to full-sun sites with moderate, regular watering, and benefits from periodic deadheading to promote continuous blooms. This low-input plant is an excellent choice for erosion control, butterfly gardens, and seaside landscapes.
