The Florida black-eyed Susan is a rare, endemic variety found exclusively in Florida, making it a wonderful choice for native and wildlife-friendly gardens in the region. It grows well in part shade to full sun with average moisture and tolerates the sandy, well-drained soils typical of Florida landscapes. Deadhead regularly to extend the blooming season, and allow some seed heads to mature to support local bird populations.
