If you’re looking to add some authentic southwestern character to your garden, desert twinbugs (Dicoria canescens brandegeei) might be just the native annual you’ve been searching for. This unassuming little forb brings a piece of the American Southwest right to your backyard, though you’ll want to know a few important things before adding it to your plant wish list.

What is Desert Twinbugs?

Desert twinbugs is a native annual forb that belongs to the diverse world of non-woody plants. As a forb, it’s essentially an herbaceous flowering plant that completes its entire life cycle in just one growing season. Don’t let the twinbugs name fool you – this plant isn’t related to insects at all! The name likely refers to some aspect of its flowers or seeds that reminded early botanists of paired bugs.

You might also encounter this plant under several scientific synonyms, including Dicoria brandegeei, Dicoria canescens var. brandegeei, or Dicoria paniculata, depending on which botanical reference you’re consulting.

Where Does It Call Home?

This native beauty hails from the southwestern United States, where it naturally occurs across Arizona, Colorado, New Mexico, and Utah. It’s perfectly adapted to the unique growing conditions of this region, making it an excellent choice for gardeners in these areas who want to create landscapes that reflect their local ecosystem.

Should You Grow Desert Twinbugs?

Here’s where things get a bit complicated. While desert twinbugs is undeniably a worthy native plant, it comes with an important conservation consideration. This subspecies has a Global Conservation Status that suggests it may be of some conservation concern. This means that if you’re interested in growing desert twinbugs, you’ll want to be extra careful about sourcing.

Responsible Gardening Practices

If you decide to include desert twinbugs in your garden, please follow these responsible gardening guidelines:

  • Only purchase from reputable native plant nurseries that ethically propagate their plants
  • Never collect seeds or plants from wild populations
  • Ask your nursery about the source of their desert twinbugs plants
  • Consider supporting conservation efforts for southwestern native plants

  • Adding seasonal interest that changes each year
  • Filling in gaps between perennial plantings

  • Supporting authentic regional plant communities

Growing Conditions and Care

Unfortunately, specific growing information for this particular subspecies is quite limited in available botanical literature. However, as a native plant of the southwestern United States, desert twinbugs likely thrives in conditions typical of this region. This generally means it probably prefers well-draining soils and can handle the temperature extremes common to areas like Arizona, Colorado, New Mexico, and Utah.

Since it’s an annual, you can expect desert twinbugs to complete its entire life cycle – from germination through flowering and seed production – in a single growing season.

The Bottom Line

Desert twinbugs represents the kind of specialized native plant that makes southwestern gardening so unique and rewarding. While the limited availability of detailed growing information makes it somewhat of a gardening adventure, its native status and regional authenticity make it worth considering for dedicated native plant enthusiasts.

Just remember to source responsibly, and don’t be discouraged if this particular plant proves elusive. The world of southwestern native plants is rich and diverse, with many other wonderful annual forbs that might be more readily available while you search for desert twinbugs from ethical sources.

After all, every native plant we successfully grow – no matter how small or seemingly insignificant – is a victory for local ecosystems and a step toward more sustainable, regionally appropriate gardening.
