Q.Wilting Texas Star Hibiscus
Notice both red and white Texas Star Hibiscus begin to droop in late afternoon (Louisiana 8B), either in ground or pot. Suggestions? Thanks, Merrily

Without photos of the plant, the soil around them, and some information on temperature, watering, and other information on the conditions around the plant, it would be hard to say. Please include detailed information on these things and I will be more than glad to help.
Drooping can often happen in the afternoon in high temperatures.
If your plantings are new, they may need some time to adjust to full sun.
Try giving them morning sunshine and afternoon shade. If they are directly planted into the ground; add a shade cloth for the hottest part of the day.
Make sure the plants are watered well; container plants will need watering more frequently.
Add mulch to ground plantings to help with moisture retention and keeping roots cool.
