Limpia Blacksenna: A Hidden Gem of Texas Native Wildflowers

If you’re looking for a native wildflower that’s as tough as Texas itself, let me introduce you to limpia blacksenna (Seymeria scabra). This scrappy little annual might not be the showiest flower in the garden, but it’s got character in spades and plays an important role in supporting local ecosystems.

What Is Limpia Blacksenna?

Limpia blacksenna is a native Texas annual forb – that’s gardener-speak for a non-woody herbaceous plant that completes its entire life cycle in one growing season. As a true Texas native, this plant has adapted perfectly to the challenging conditions of the Lone Star State, making it an excellent choice for gardeners who want to work with nature rather than against it.
