Texas is a great place to live for most of the year. Texas yards are envied by people living elsewhere as they shine lively in the spring and fall and have flowers blooming all year long. However, selecting the perfect flowers to grow in Texas is more difficult than one might imagine. Some plants need a lot of attention, some are pest-prone, and many are just too complicated or slow-growing to be practical.

Despite all the benefits of living in Texas, one thing cannot be denied: it can get very hot, especially in the summer. Living in Texas means you should be prepared for extended periods of heat and drought. So, if you are a gardener or just love planting flowers around your home, below are the best flowers to plant in Texas that are guaranteed to survive the heat and intense climate changes in the Lone Star State.

17 Best Flowers to Plant in Texas

1. Hibiscus

The first image that comes to mind when you imagine a tropical rainforest is hibiscus blossoms. The Texas Star Hibiscus has large, solitary, scarlet flowers of three to four inches wide that are carried on stems of palmately lobed leaves with three to seven segments. They do require higher temperatures where there is adequate humidity for them to grow. As long as summertime temperatures don’t exceed 95°F (35°C), the hibiscus thrives.

2. Daisies

Daisies are ideal for planting anywhere in your Texas yard because they thrive in higher temperatures and sunlight. Cold and wet weather frequently leads to an increase in disease and fungus. Although it doesn’t happen frequently, daisy plants fall prey to fungus and disease, which results in no blooms or the flower dies. Plant daisies in the spring and bulbs in the fall to see this lovely bloom return yearly with little to no upkeep.

3. Columbine

In the heat of Texas, both red and yellow columbines thrive, but they do best in wet, well-drained soil. When there is a lack of water in the summer, columbines frequently become dormant. Hummingbirds swarm to these blossoms in large numbers.

4. Salvia farinacea

One of Texas’ more well-known spring flowers, Cape plumbago, blooms abundantly from May until the first frost. The cape plumbago originates from warm, temperate, tropical regions, primarily South Africa. Despite being a sensitive perennial, Cape plumbago can withstand Texas’ midsummer heat and humidity. It thrives in environments with regular grass mowing, sandy, light soil with adequate drainage, and plenty of organic materials. The flowers have a phlox-like appearance and draw a variety of butterflies.

6. ‘John Fanick’ Phlox

‘John Fanick’ Phlox, a stunning bicolor with lavender-and-pink blooms, is named after a San Antonio nurseryman. It can stand both heat and humidity. Grow it in full sun to partial shade on moderately healthy, well-drained soil. Smaller phlox frequently succumb to powdery mildew disease, although the foliage’s waxy nature deters it. It can be grown in a small, 2-foot wide, 3-foot tall package.

7. Fall Aster

This natural shrub can withstand both sun and partial shade and has tiny, beautiful purple flowers. As the name implies, the plant’s flowers are at their greatest in the fall months, and it provides nectar. This plant needs little pruning in the spring and summer to maintain its compact shape.

The cultivars of Cherry (or Autumn), Cedar, Mealy Blue, Mexican Bush, Jerusalem, Majestic, San Luis, Russian, and Tropical Sage are incredibly tough and can easily tolerate the Texas heat.

The lantana makes the ideal companion plant for outdoor activities with its luscious orange, yellow, pink, or lavender blossoms flooding your containers. Lantana prefers hot, humid weather because it is a native of the tropics and thrives in moist, well-draining soil but can overcome drought conditions. It blossoms all year long in close clusters of red, pink, orange, yellow, or white and flourishes in the light, particularly the afternoon sun. Since the flowers are enticing to butterflies, bees, and hummingbirds, they are perfect for growing along the edges of vegetable gardens.

11. Turk’s Cap

Petunias are a wonderful annual flower that blooms until the beginning of November but truly does best in hot weather. You’ll notice more flowers as the temperature rises. On the tips of the one-foot stalks, trumpet-shaped, violet-blue flowers bloom, which are very showy due in part to the clouds of butterflies they draw. Although they may tolerate some shade, these perennials like full sunlight and will flower less in low light conditions.

13. Zinnias

Zinnias are one of the few spring flowers that can be sown in early summer and still blossom and grow. However, you can plant them in the spring to give them a head start. The sun-loving, quick-blooming zinnias create daisy-like flowers with thick, emerald-green leaves. Our fellow pollinators love zinnias, and they can withstand heat and drought. Although they are lovely blossoms, the fungus can cause root rot if the soil becomes too damp.
