Tips for Growing Flowers Successfully in the Texas Summer Heat
Texas summers present some unique challenges for gardens. Use these tips to help your flowers thrive in the intense heat and sun:
-
Plant in well-draining soil to prevent soggy roots. Incorporate compost or other organic matter to improve drainage.
-
Mulch flower beds and containers to retain soil moisture longer. 2-3 inches of organic mulch like bark or pine straw works great.
-
Water deeply and less frequently to encourage deep root growth. About 1-2 inches per week is sufficient for most plants.
-
Provide afternoon shade if possible – a trellis canopy, or strategically placed plants helps prevent wilting.
-
Use containers with light-colored glazes to help moderate soil temperature and reduce water loss.
-
Fertilize throughout the growing season to support flowering and health. Apply products designed for blooming plants.
-
Remove spent blooms and dead leaves often to maintain a tidy appearance and promote new growth.
-
Monitor for pests like aphids and caterpillars which can thrive in summer’s heat and humidity. Take action early to avoid major damage.

The Best Heat Tolerant Plants for Texas (And How to Help Them Thrive)
To say that our trees, shrubs, and flowers need to hold up under intense heat is an understatement. If you’re not careful, you can choose plants that will die quickly in our hot, dry climate. That’s why we’ve put together this list of the best heat-tolerant plants for Texas.
We’ve been landscaping in and around Dallas/Fort Worth for decades, so we know how different plants do during the different seasons. The weather is getting cooler, and winter is coming, but it’s still not too early to start thinking about what you’ll plant in the spring.
Around here, we’re never too far away from hot days. So here are some plants that can take whatever Texas throws at them and still keep looking good!.
All plants need three things to thrive: sunlight, air, and water. Unfortunately, too much of any of those can cause problems.
- Too much water…they can drown.
- Too much air…they can blow away.
- Too much sun…they can cook.
We enjoy abundant sunlight here In Texas. This is one of the many great things about living here, but it also means there is plenty of heat. If you want a landscape that looks good even during the hottest summer days, you should only plant things that do well in our harsh growing conditions.
However, before we start, please keep in mind that no plant can be sure to survive if things get too bad. In 2020, Texas had record-breaking high temperatures in the summer and freezing low temperatures in the winter. Sometimes, in spite of your best efforts, nature wins in the end and your plants don’t make it.
Regardless of what shrubs and flowers you select, here are a few key rules to keep in mind:
- Put the right plant in the right place. Pay close attention to the tags and look for plants that can handle 6 to 10 hours of direct sunlight with little to no watering. Watch out for tags that say “low water” and “heat tolerant.” “These choices will be much less stressed by our summer weather than less hardy plants
- Don’t give up when they look weak. When it gets hot, even the toughest plants and flowers can start to look sad. To save energy during the hottest parts of the season, they often go into a protective mode that’s like hibernation. If this happens, they might not bloom anymore, and the leaves might curl or shrink. If that happens, don’t get rid of the plant right away because you think it’s dying. Keep it watered and fertilized (but don’t overdo it). Then keep an eye on it all summer to see if it starts to grow again when the weather gets cooler.
Now let’s take a look specifically at shrubs and flowers. You can bring these lists with you to your next meeting with a landscape designer or to the nursery near you.
Here is a list of heat resistant or tolerant shrubs as recommended by the Texas Superstar program of Texas AgriLife Research:
- Blue Angel™ Althea
- Lynn’s Legacy Cenizo
- Belinda’s Dream Rose
- Grandma’s Yellow Rose
- KNOCK OUT® Rose
- ‘Marie Daly’ Rose
- Rock Rose
- Texas Lilac Vitex
Next, here is a list of solid choices for heat-resistant flowers:
This list is divided into two categories: perennials and annuals. Every year, perennial flowers come back, or if the conditions are right, they keep growing. This makes them easy to grow. Annuals only last for one season, so they need to be planted year after year. There are advantages and disadvantages to both, so we’ll cover those as we go along. Here are the flowers that seem to do best in hot Texas weather.
- Plants that can handle high temperatures include lantana, aloe, black-eyed Susan, butterfly bush, columbine, Texas gold, cone flower, goldstrum rudbeckia, hibiscus (varieties include Flare, Lord Baltimore, Texas Star, and Moy Grande), mealycup sage, pink muhly grass, purple fountain grass, verbena – blue princess, and yucca.
- Begonia, Caladium, Coleus, Impatiens, Sunpatiens, and Lantana are all annual plants that can handle the heat in Texas. However, in northern Texas, the winter temperatures may be too low for these plants to survive. In planting zones 6 and 7 MarigoldPetuniaSalvia – varieties: Henry Duelberg, Mystic Spires BlueZinnia.
