Rio Grande Wild Petunia: A Rare Texas Native Worth Knowing About
Meet Ruellia davisiorum, better known as Rio Grande wild petunia – a fascinating native plant that calls Texas home. If you’ve never heard of this little gem, you’re not alone! This perennial wildflower is one of those special plants that reminds us just how diverse and wonderful our native flora can be, even when they prefer to stay under the radar.
What Makes Rio Grande Wild Petunia Special?

Where Does It Call Home?
Rio Grande wild petunia is native to Texas, where it has adapted to thrive in the unique conditions of the region. As a plant that’s evolved specifically for this area, it represents the kind of perfectly adapted native species that can truly shine in the right Texas garden.
