Finding the right plants for your sunny Florida yard can feel like a challenge. The good news is there are many excellent Florida ground cover plants thriving in sunny landscapes that handle the heat, humidity, and sandy soil with ease. These tough plants solve common problems, from covering bare spots to preventing erosion, all while adding beauty with less work than a traditional lawn.
Florida Ground Cover Plants – Thriving In Sunny Landscapes
This group of plants is specialy adapted to our unique climate. They don’t just survive the full sun; they prosper in it, often needing far less water and care than non-native options. By choosing the right ground cover, you create a living carpet that supports local wildlife and cuts down on your gardening chores.
Why Choose Ground Covers for Florida Sun?
Ground covers are more than just pretty. They are practical problem-solvers for any Florida landscape. Once established, they form a dense mat that blocks out weeds, saving you hours of pulling. Their roots hold soil in place during our heavy summer rains, preventing ugly and damaging erosion on slopes or in open beds.
They also help the soil retain moisture, which means you water less often. Many are drought-tolerant, a key feature during our drier months. Plus, they provide essential habitat for pollinators like bees and butterflies, making your garden a part of Florida’s ecosystem.
Top Picks for Full Sun Ground Covers
Here are some of the most reliable and beautiful choices. These plants have proven they can handle the relentless Florida sun.
Beach Sunflower (Helianthus debilis)
This cheerful native is a superstar. It spreads quickly, offering bright yellow, daisy-like flowers nearly year-round. It’s salt-tolerant, perfect for coastal areas, and thrives in poor, sandy soil. It reseeds readily, so it will naturalize and fill in large areas.
- Sun: Full sun.
- Water: Very drought-tolerant once established.
- Height: 1-2 feet tall, spreads several feet wide.
- Note: It has a casual, informal look; let it spread naturally.
Perennial Peanut (Arachis glabrata)
For a lawn alternative, it’s hard to beat perennial peanut. It forms a thick, green carpet of clover-like leaves and sports small, bright yellow flowers. It’s tough, requires no mowing, and actually improves soil by adding nitrogen.
- Sun: Full sun to very light shade.
- Water: Moderate; drought-tolerant but looks best with occasional watering.
- Height: 6-12 inches tall.
- Note: Not for heavy foot traffic, but great for visual areas and slopes.
Mondo Grass (Ophiopogon japonicus)
While not a true grass, mondo grass provides a fine-textured, grass-like appearance. It’s incredibly versatile and forms tidy clumps that slowly spread. The dark green color offers a beautiful contrast to brighter plants. Dwarf varieties are especially neat for edges.
- Sun: Full sun to full shade (colors best in sun).
- Water: Moderate; keep moist until established.
- Height: 6-10 inches tall.
- Note: Very low-maintenance and rarely bothered by pests.
Sunshine Mimosa (Mimosa strigillosa)
This Florida native is a fast-spreading, low-growing plant with fern-like leaves that fold up when touched. Its fluffy, pink, pom-pom flowers are a magnet for butterflies. It’s very aggressive, making it ideal for large, tough areas where you need quick coverage.
- Sun: Full sun to partial shade.
- Water: Drought-tolerant.
- Height: Only 3-6 inches tall, but spreads widely.
- Note: Can be invasive in mixed beds; best used in dedicated areas.
Blue Porterweed (Stachytarpheta spp.)
For a taller ground cover or small shrub effect, choose blue porterweed. It produces long spikes of attractive blue or purple flowers that butterflies adore. The native species is a long-lived perennial that spreads willingly.
- Sun: Full sun.
- Water: Drought-tolerant once established.
- Height: 2-4 feet tall and wide.
- Note: Choose the native Stachytarpheta jamaicensis for best wildlife value.
How to Plant and Establish Your Ground Cover
Getting your plants off to a strong start is key to there success. Follow these steps for a healthy, spreading bed.
- Prepare the Site. Clear all existing weeds and grass. Till or loosen the top 6-8 inches of soil. Mix in some compost to improve poor sandy soil, which helps with moisture retention.
- Space Plants Correctly. Check the plant tag for recommended spacing. For fast coverage, you can place them a bit closer, but don’t overcrowd. For example, space perennial peanut plugs about 1 foot apart.
- Plant at the Right Depth. Dig a hole just as deep and twice as wide as the root ball. Place the plant so the top of the root ball is level with the soil surface. Backfill and gently firm the soil.
- Water Deeply and Mulch. Water each plant thoroughly after planting. Apply a 2-inch layer of pine straw or shredded bark mulch around plants to supress weeds and conserve moisture. Keep mulch away from plant stems.
- Initial Watering Schedule. Water daily for the first week or two, then gradually reduce to 2-3 times per week for the next month. Once you see significant new growth, you can rely on rainfall, watering only during extended dry spells.
Care and Maintenance Tips
These plants are low-care, but not no-care. A little attention keeps them looking their best.
Watering Wisely
Even drought-tolerant plants need regular water to get established. After that, most will only need irrigation during prolonged drought. Water deeply and infrequently to encourage deep root growth. Early morning is the best time to water.
Fertilizing Lightly
Most Florida native ground covers need little to no fertilizer, to much can cause weak growth. If you feel you need to feed, use a slow-release, balanced fertilizer in the spring. A light layer of compost each year is often sufficient.
Managing Growth
Some ground covers, like Sunshine Mimosa, are vigorous spreaders. Use edging or regular trimming along borders to keep them in their designated area. For others, like Perennial Peanut, a yearly mow or trim on a high setting can encourage fresh growth and more flowers.
Design Ideas for Your Landscape
Think beyond just covering ground. Use these plants creatively.
- Slope Stabilization: Use fast-spreading, deep-rooted covers like Perennial Peanut or Beach Sunflower to hold a hillside.
- Lawn Replacement: Replace thirsty turf grass with Perennial Peanut or a mix of low-growing herbs for a fragrant, flowering “lawn.”
- Under Trees: Use shade-tolerant sun covers like Mondo Grass in sunny patches under high-branched trees where grass struggles.
- Pathway Borders: Edge your garden walks with neat, low clumps of Dwarf Mondo Grass for a clean, defined look.
- Color Themes: Plant masses of Beach Sunflower for a bright yellow display, or use Blue Porterweed for cool purple tones.
Common Problems and Solutions
Even the toughest plants can have occasional issues. Here’s what to watch for.
Weeds: Keep weeds under control while your ground cover is filling in. Hand-pull carefully to avoid disturbing new plants. Once the cover is dense, weeds will be mostly blocked out.
Pests: Few pests bother these hardy plants. Chewing insects may leave holes in leaves, but rarely threaten the plant’s health. Encourage natural predators like birds and lizards. If needed, use a strong spray of water or an organic insecticidal soap.
Fungal Disease: In our humid climate, allow for good air circulation. Avoid overhead watering in the late afternoon or evening. If you see spotted or mildewed leaves, remove affected foliage to prevent spread.
FAQ
What is the fastest spreading ground cover for full sun in Florida?
