1. Zinnias
Zinnias thrive in the heat and keep blooming without missing a beat during the hottest months. They come in a wide range of colors, except blue, so you get plenty of variety. With their upright stems, they’re also a reliable pick for cut flower arrangements that hold up well indoors.
2. Marigolds
If you're looking for flowers that do double duty, marigolds fit the bill. Their strong scent helps keep garden pests like nematodes and aphids in check, which is why they’re planted alongside vegetables. In many cultures, these bright blooms are symbols of protection and good vibes.

3. Coneflowers
Native to North America, coneflowers are built for dry conditions. Beyond their looks, these flowers have long been valued in herbal medicine for potential immune support. Even after blooming, their seed heads stick around, offering food for birds.
4. Sunflowers
As sunflowers grow, young plants actually track the sun across the sky—a behavior called heliotropism. By season’s end, many reach over 12 feet tall. Moreover, sunflowers aren’t just for show, as nearly every part of the plant has a use, from the edible seeds to the sturdy stalks.
5. Petunias
Petunias bring nonstop color from spring through the first frost, making them a reliable choice for a long-lasting display. With varieties that ruffle, cascade, or show off stripes and spots, there’s no shortage of visual interest. Plus, newer hybrids are built to handle rain better.
6. Black-Eyed Susans
Black-Eyed Susans are the kind of flower that quietly takes over in the best way. Their golden-yellow petals brighten up any space, even in poor soil conditions. They're also known to symbolize encouragement, which explains their popularity in healing and therapeutic gardens.
7. Cosmos
Cosmos are the overachievers of poor soil, as they flourish where fussier plants fail. With delicate foliage and soft pastel flowers, they bring an effortless wildflower feel to any garden. Interestingly, these self-sowing charmers spread easily, needing almost no help to come back each year.
8. Coreopsis
Nicknamed “tickseed,” coreopsis is a hardworking bloomer that carries on from June right through to the first frost. Its bright, daisy-like flowers lift the mood of any space. The seeds are a favorite snack for goldfinches, while the blooms attract helpful predators that keep pests in check.
9. Lantana
The blooms of Lantana change color as they age, creating a constantly shifting display of pinks, oranges, and yellows. Their salt tolerance also makes them a go-to choice for coastal gardens. And if you brush past the foliage, you’ll catch a whiff of its citrusy scent, which adds one more layer to its appeal.

12. Verbena

13. Geraniums
Zonal geraniums are a classic choice for reliable summer color, especially in hot conditions. They bloom steadily and do well in pots or directly in garden beds. Plus, the essential oils found in geraniums are often used in natural insect repellents, offering both beauty and practical value for outdoor spaces.

Known for its strikingly unusual blooms, celosia adds bold texture and color wherever it’s planted. Its flowers come in plume or brain-like shapes, usually in vivid neon shades. Beyond looks, some varieties are edible and widely used in West African cuisine.
18. Portulaca
When you need color in the most sunny corners of your garden, portulaca steps up effortlessly. Also called moss rose, this tough little plant thrives in sandy soil and stores water in its succulent leaves. Moreover, in warmer climates, it self-sows and often returns on its own.
