If you’re looking to add authentic southwestern flair to your garden while supporting local wildlife, New Mexico groundsel might just be the hidden gem you’ve been searching for. This cheerful native perennial brings sunny yellow blooms and low-maintenance charm to gardens across the American Southwest.

What Is New Mexico Groundsel?

New Mexico groundsel (Packera neomexicana var. mutabilis) is a native herbaceous perennial that belongs to the sunflower family. As a forb, it produces soft, non-woody stems that die back each winter, returning fresh and vibrant each spring. You might occasionally see this plant referenced by its former scientific names, Senecio mutabilis or Senecio neomexicanus var. mutabilis, but don’t let the name changes confuse you—it’s the same delightful plant.

Where Does It Grow Naturally?

This true American native calls the Southwest home, naturally occurring across Arizona, Colorado, New Mexico, and Utah. It has adapted beautifully to the region’s challenging growing conditions, making it an excellent choice for gardeners who want to work with nature rather than against it.

Why Grow New Mexico Groundsel?

There are several compelling reasons to consider adding this native beauty to your landscape:

  • Native authenticity: As a true native plant, it supports local ecosystems and provides habitat for regional wildlife

  • Wildflower meadows: Let it naturalize alongside other native wildflowers
  • Pollinator gardens: Essential for supporting native bee and butterfly populations

Growing Conditions

New Mexico groundsel thrives when you give it conditions similar to its native habitat:

  • Sunlight: Full sun to partial shade

  • Spacing: Allow adequate space for the plant to spread naturally
  • Soil preparation: Ensure excellent drainage; amend heavy clay soils with sand or gravel

  • Maintenance: Deadhead spent flowers to encourage continued blooming, though you can leave some for wildlife

A Word of Caution

While specific information about this particular variety is limited, it’s worth noting that some members of the Packera genus can be toxic if ingested. Keep this in mind if you have curious pets or children who might be tempted to nibble on garden plants.
