Florida’s abundant sunshine makes it a paradise for gardeners, but the intense heat, high humidity, and sandy soils present unique challenges for growing plants in full sun. Full sun conditions—defined as at least six hours of direct sunlight daily—require plants that are heat-tolerant, drought-resistant, and adaptable to Florida’s subtropical and tropical climate. Whether you’re landscaping a yard in Miami, designing a garden in Orlando, or enhancing a patio in Jacksonville, choosing the right plants is key to creating a vibrant, low-maintenance landscape. This guide explores the best plants for full sun in Florida, including native and Florida-friendly options, with tips for success across the state’s diverse regions.
Understanding Florida’s Full Sun Conditions
Florida’s climate varies from subtropical in North and Central Florida (USDA Hardiness Zones 8b–9b) to tropical in South Florida (Zones 10–11). Full sun plants must withstand intense sunlight, temperatures often exceeding 90°F, and humidity levels that promote fungal diseases. The state’s wet season (May to October) brings heavy rainfall, while the dry season (November to April) requires irrigation for many plants. Sandy soils, common across Florida, drain quickly, necessitating plants that tolerate drought or require soil amendments.
Key Considerations for Full Sun Plants
- Heat Tolerance: Plants must endure high temperatures and direct sunlight without wilting.
- Drought Resistance: Many full sun plants need to tolerate dry periods, especially in the dry season.
- Disease Resistance: High humidity can lead to fungal issues like powdery mildew, so choose resistant varieties.
- Soil Adaptability: Plants should thrive in sandy, well-drained soils or benefit from organic amendments.
- Regional Suitability: North, Central, and South Florida have different frost risks and temperature ranges, affecting plant selection.
By selecting plants suited to these conditions, you can create a thriving, sun-loving garden in Florida.

- Increase watering during the dry season (November–April).
- Mulching:
- Apply 2–3 inches of organic mulch (e.g., pine bark or straw) to retain moisture and suppress weeds.
- Keep mulch away from plant stems to prevent rot.
- Pest and Disease Management:
- Monitor for pests like aphids, whiteflies, and caterpillars. Use neem oil or insecticidal soap for control.
- Prevent fungal diseases by ensuring good air circulation and avoiding overhead watering.
- Choose disease-resistant varieties like blanket flower or pentas.
- Fertilizing:
- Use a balanced fertilizer (e.g., 10-10-10) for flowers and vegetables, or a slow-release formula for shrubs and trees.
- Fertilize palms with a palm-specific blend (e.g., 8-2-12) to prevent nutrient deficiencies.
