Keeping your Florida garden in bloom during the dog days of summer can feel like a losing battle. The sun gets hotter, the rain gets weirder, and some plants just give up and throw in the trowel (pun intended). But don’t worry—there are plenty of plants that can take the heat and keep your garden looking alive, even when everything else is melting.
We talked to a few Florida landscape designers and asked them: What are the best late summer perennials that still look great in August and beyond? Here’s what they had to say, along with some easy tips to make your garden thrive longer without making you sweat (too much).
Why Late Summer Perennials Matter in Florida Gardens
Florida is a gardener’s paradise… if you know what you’re doing. The long growing season is great, but it also comes with challenges: intense sun, sudden rainstorms, salty air (if you’re near the coast), and soil that often needs help.
By late summer, many annuals are fried or faded. That’s where late summer perennials come in. These are tough plants that not only survive the heat but actually like it. They keep blooming into fall and save your yard from looking tired.
Florida landscape designers often rely on these plants to keep their projects looking fresh and colorful long after other flowers have quit. Let’s dig into their top picks.
Top Late Summer Perennials Florida Landscape Designers Love
1. Black-Eyed Susan (Rudbeckia hirta)
This sunny yellow flower is a classic for a reason. It blooms like it means it and keeps going well into fall. It’s drought-tolerant, attracts pollinators, and doesn’t mind sandy Florida soil.
Why designers like it: It brings a pop of color that pairs well with almost anything. And it’s low-maintenance, which everyone loves.
2. Coreopsis
This cheerful flower is actually Florida’s state wildflower. It’s easy to grow, blooms for months, and handles poor soil without complaining. The yellow varieties are most common, but you can find pink and red ones too.
Designer tip: Plant them in clusters for a wildflower-meadow look. It’s a great way to add a natural, relaxed feel to your yard.
3. Lantana
Lantana is the overachiever of late summer. It blooms like crazy, shrugs off heat, and comes in tons of colors. Some types are even salt-tolerant, making them perfect for coastal areas.
Heads-up: Some types can be invasive in certain parts of Florida, so ask your local nursery for native or sterile varieties.
4. Salvia
Salvia (especially varieties like ‘Mystic Spires Blue’ or ‘Hot Lips’) adds vertical interest and rich color. Bees and hummingbirds can’t resist it. It loves sun and doesn’t get grumpy in hot weather.
Bonus: Salvia often comes back stronger each year if you give it a good trim in the winter.
5. Gaillardia (Blanket Flower)
With bright red, orange, and yellow petals, Gaillardia looks like a Florida sunset in flower form. It thrives in sandy soil, needs very little water once established, and blooms non-stop.
Landscape designers use it: To add tropical flair to modern or beach-style gardens. It looks especially good against stone or gravel backgrounds.
Smart Design Tips from Florida Landscape Designers
You’ve picked your plants. Now how do you make your garden look like it belongs in a magazine (without the magazine-level effort)? Here are some tricks Florida landscape designers swear by:
1. Layer Your Plants
Use a mix of tall and short perennials. Place taller ones like Salvia or Lantana in the back, and use shorter bloomers like Coreopsis up front. It creates depth and makes even small gardens look bigger.
2. Pick a Color Theme
If you throw every color into your garden, it can get loud fast. Stick with a palette—warm colors like reds, yellows, and oranges work great in Florida and hold up well in bright sun.
3. Keep It Low Maintenance
Florida landscape designers love perennials because they come back year after year. But even low-maintenance plants need some care:
- Mulch to keep roots cool.
- Deadhead old blooms to keep the show going.
- Water early in the morning to avoid mildew and evaporation.
4. Don’t Forget the Pollinators
A mix of native and hardy perennials can turn your yard into a butterfly buffet. Salvia, Lantana, and Gaillardia are all pollinator magnets.
Common Mistakes to Avoid
Even with the best plants, there are a few pitfalls to watch out for. Here are the usual suspects, according to Florida landscape designers:
- Planting too late: Get your late-summer bloomers in the ground by early July if you want flowers by August.
- Skipping soil prep: Florida soil is often sandy and lacking nutrients. Mix in compost before planting.
- Overwatering: These perennials are tough. Too much water can actually harm them. Let the top inch of soil dry out between watering.
- Choosing the wrong variety: Not all perennials are Florida-friendly. Always double-check with your local nursery or designer.
Where to Find These Plants in Florida
You don’t have to travel far to find these summer heroes. Most local garden centers carry them, especially those that specialize in Florida-native or heat-tolerant plants. You can also check:
- Florida Native Plant Society plant sales
- Master Gardener events
- Local nurseries that work with Florida landscape designers
Pro tip: If you’re unsure where to start, many Florida landscape designers offer consultations to help you build a plant list that suits your yard’s sun, soil, and size.
Final Thoughts
Summer in Florida doesn’t have to mean fried flowers and faded gardens. With the right late summer perennials, your landscape can stay colorful, healthy, and buzzing with life well into fall.
By listening to the advice of seasoned Florida landscape designers, you can enjoy a yard that doesn’t just survive the summer—it thrives in it. So grab a trowel, pick a palette, and plant something that’ll still be showing off when the rest of the neighborhood has wilted.
