What would be a good selection of flowers to plant in a Texas garden?

I’m a teen and I signed up for the whole “Nickelodeon’s The Big Help”. I pledged to plant a garden, so I thought about flowers in my front lawn. (My mom says it’s okay.) We want flowers that wont attract too many bugs, looks pretty, and is great with a medium sized lawn. What flowers would the expert gardeners recommend?
It’s around 90 degrees, and I want the flowers in the sun.

Check for native plants and use those. There are lots of wild flowers in Texas and they vary by region. Ask at a garden shop.
