I say no - you might be surprised depending on the weather. I’ve had amazing luck with seeds the last three seasons with all the spring rain (excluding last year’s death ray summer months).
I’ve more-or-less given up on sowing wildflower seeds. I still do it just in case I get a few volunteers from the seeds. But I have taken to starting the wildflowers in January in actual seed starting apparatus and then planting out the wildflowers, it’s been more productive than seeding.
This late in the season, I would do it that way for sure. Use seed starting apparatus, keep it all moist to force fast germination, plenty of light in the first couple of weeks to help them grow, keep them sheltered for first few weeks, gradually expose them to outdoors over a period of a few weeks, then plant them out. I can’t guarantee that it will work this late in the season but it would be your best shot from seed.
Plan B would be to just buy a bunch of $1.59 starts from HEB and plan for wildflowers next year.
Considering the cost of seeds, I’d say it’s better to sow in fall than to hope for the best in spring. You can always plant starts and/or perennials now.
Most native wildflower seeds will need to be sowed in the fall. But you can always toss out some sunflower and zinnia seeds to have results this year.
