Soft Feather Pappusgrass: What You Need to Know About This Uncommon Grass

If you’ve stumbled across the name soft feather pappusgrass in your plant research, you might be wondering what exactly this grass is all about. Also known by its scientific name Enneapogon cenchroides, this is one of those plants that doesn’t get much spotlight in the gardening world – and there are some good reasons why.

The Basics: What Is Soft Feather Pappusgrass?

Soft feather pappusgrass belongs to the grass family and can grow as either an annual or perennial, depending on conditions. Like other grasses, it’s what botanists call a graminoid – basically a fancy way of saying it’s grass-like in its growth pattern and appearance.

You might occasionally see this plant listed under an older scientific name, Enneapogon mollis, but Enneapogon cenchroides is the currently accepted botanical name.

Where Does It Grow?

Here’s where things get interesting (and a bit concerning): soft feather pappusgrass isn’t actually native to the United States. It’s an introduced species that has managed to establish itself and reproduce on its own in Arizona. This makes it what ecologists call a naturalized non-native plant.

  • No observations

Should You Plant It in Your Garden?

Here’s the thing – there’s very little information available about this particular grass species when it comes to gardening and landscaping. We don’t know much about:

  • Its growth habits and mature size
  • Specific care requirements
  • Whether it provides benefits to wildlife
  • Its potential to become invasive
  • How it performs in different climate zones

When you’re dealing with a non-native plant that has limited cultivation information, it’s usually wiser to look elsewhere for your landscaping needs.

Better Alternatives: Native Grass Options

Instead of taking a chance on soft feather pappusgrass, consider these well-documented native alternatives that will definitely benefit your local ecosystem:

  • Blue grama (Bouteloua gracilis) – A beautiful drought-tolerant native grass perfect for southwestern gardens
  • Buffalo grass (Poaceae dactyloides) – An excellent low-maintenance lawn alternative
  • Little bluestem (Schizachyrium scoparium) – Offers stunning fall color and supports native wildlife
  • Sideoats grama (Bouteloua curtipendula) – Attractive seed heads and excellent erosion control

The Bottom Line

While soft feather pappusgrass isn’t necessarily a bad plant, it’s not the best choice for most gardeners. With so many fantastic native grass options available that we know will thrive and support local wildlife, why take a gamble on something with so many unknowns?

If you’re specifically interested in this plant for research purposes or have encountered it growing wild, that’s a different story. But for the average home gardener looking to create beautiful, sustainable landscapes, you’ll find much better success with native alternatives that have proven track records.

Remember: the best garden plants are the ones that work well in your specific location while supporting the local ecosystem. Native plants almost always fit this bill better than their non-native counterparts!

Enneapogon cenchroides is also known as...

Often we refer to plants by their common names. When shopping for plants the scientific name is the best way to positively identify the plant species you desire. But some plants have more than one name! While it doesn't happen often, nurseries might display one name while you're searching for another. Enneapogon cenchroides is also known as:

Enneapogon mollis auct. non | USDA symbol: ENMO

Why do some plants have more than one name? Over time plant species may be renamed for a few reasons:

  1. Botanists in different regions named the same plant without knowing it had already been classified.
  2. A species was reclassified after scientific advances in, for example, DNA analysis.
  3. Slight variations within a species are sometimes mistakenly identified as entirely new species.
