When the Texas summer sun cranks up the heat, not all flowers can take the pressure. But that doesn’t mean your garden has to fade. There are several heat-tough annuals that actually thrive in the summer and keep blooming all season long with just a little care. Four of our favorites? Periwinkles, Pentas, Angelonia, and Zinnias.
Periwinkles (Vinca)
Periwinkles are practically made for hot, dry Texas summers. These low-maintenance annuals are drought-tolerant, heat-loving, and bloom nonstop until the first frost. Their glossy green foliage and wide range of flower colors—white, pink, red, purple—make them a versatile choice for mass plantings or borders.
Care Tips:
- Full sun is essential
- Well-draining soil is required (avoid soggy spots)
- Water at the base to prevent fungal issues

Pentas
Need to attract pollinators like butterflies and hummingbirds? Pentas are your go-to. Clusters of star-shaped blooms are packed with nectar and love the heat. They’re a great filler for flower beds or large containers, and they come in shades of pink, lavender, red, and white.
Care Tips:
- Full sun to part sun
- Water regularly, but don’t overdo it
- Optional: Deadhead spent blooms to encourage new growth

- Minimal maintenance—just enjoy the blooms!

Zinnias are a classic summer favorite for a reason. They’re bright, cheerful, easy to grow from seed or transplant, and irresistible to butterflies. With their wide variety of colors, heights, and bloom types, you can find a zinnia for just about every sunny spot.
Care Tips:
- Full sun required
- Deadhead regularly for continuous blooms
- Allow some blooms to go to seed for volunteer plants next year
