Carrizo Creek Ragwort: A Rare Native Treasure Worth Protecting
If you’re passionate about native plants and conservation gardening, you might be intrigued by Carrizo Creek ragwort (Packera spellenbergii). But before you start planning where to plant this New Mexico native, there’s something important you need to know: this little wildflower is fighting for survival.
What Makes This Plant Special
Carrizo Creek ragwort is a perennial forb that belongs to the sunflower family. Like other ragworts, it produces cheerful yellow daisy-like flowers that bloom from spring into early summer. The plant forms an attractive basal rosette of leaves and sends up flowering stems when conditions are right.
You might also see this plant listed under its former scientific names, Senecio cliffordii or Senecio spellenbergii, but botanists have since moved it to the Packera genus where it belongs today.
Where Does It Grow?
This ragwort is endemic to New Mexico, meaning it naturally occurs nowhere else on Earth. Its common name gives away its origin story – it was discovered in the Carrizo Creek area of Lincoln County. The plant’s entire natural range is incredibly limited, which brings us to an important conservation concern.

Why This Plant Needs Our Help
Here’s where things get serious: Carrizo Creek ragwort has a Global Conservation Status of S2, which means it’s imperiled. With only 6 to 20 known occurrences and somewhere between 1,000 to 3,000 individual plants remaining in the wild, this species is teetering on the edge of extinction.
This rarity status means that if you’re considering growing this plant, you have a responsibility to source it ethically. Never collect seeds or plants from wild populations, and only purchase from reputable native plant nurseries that propagate from legally and sustainably obtained stock.
Growing Conditions and Care
As a New Mexico native adapted to arid conditions, Carrizo Creek ragwort likely thrives in:
- Well-draining soils
- Full sun to partial shade
- Low to moderate water once established
- USDA hardiness zones 4-8
The plant’s wetland status varies by region, but it generally prefers upland conditions and rarely occurs in wetlands. This makes it well-suited for xeriscaping and water-wise native gardens.
Benefits for Wildlife and Pollinators
While specific wildlife benefits for this rare species aren’t well-documented, ragworts in general are valuable pollinator plants. The bright yellow flowers likely attract native bees, butterflies, and other beneficial insects during their blooming period.
Should You Plant It?
If you’re committed to conservation and can source Carrizo Creek ragwort responsibly, growing it can be part of important ex-situ conservation efforts. However, given its rarity and specialized needs, this isn’t a plant for casual gardeners.
For most native plant enthusiasts, consider supporting this species through:
- Donations to conservation organizations working in New Mexico
- Planting other native Packera species that are more common
- Creating habitat for native pollinators with abundant native alternatives
- Supporting research and conservation efforts for rare plants
The Bottom Line
Carrizo Creek ragwort represents both the beauty and fragility of our native plant heritage. While it might not be the right choice for every garden, raising awareness about rare plants like this one helps us appreciate the incredible diversity we’re working to protect. If you do choose to grow it, you become part of a conservation effort that could help ensure future generations get to enjoy this unique piece of New Mexico’s natural legacy.
