Ditch Rabbitsfoot Grass: A Wetland Wanderer in Your Garden

If you’ve ever spotted a soft, fluffy grass growing near ditches, pond edges, or other wet spots, you might have encountered ditch rabbitsfoot grass (Polypogon interruptus). This unassuming little grass has made itself quite at home across much of North America, though it originally hails from Mediterranean regions far from here.

Getting to Know Ditch Rabbitsfoot Grass

Also known as ditch polypogon, this perennial grass belongs to the same family as your lawn grass, but it has very different habitat preferences. True to its common name, you’ll typically find it growing in ditches, along stream banks, and in other consistently moist areas where many plants struggle to establish.

The rabbitsfoot part of its name becomes clear when you see its distinctive seed heads – they’re soft, cottony, and undeniably fuzzy, resembling the soft pads of a rabbit’s foot. These delicate plumes give the plant a gentle, almost ethereal appearance when they catch the light.

Where You’ll Find It

This adaptable grass has spread across a impressive range of states including Arizona, California, Colorado, Hawaii, Louisiana, Nebraska, Nevada, New Mexico, New York, Oklahoma, Oregon, Texas, Utah, Washington, Wisconsin, and Wyoming, plus territories like Guam and various U.S. Minor Outlying Islands. It’s particularly common in the western United States, where it thrives in irrigated areas and natural wetlands.

A Plant That Loves Its Water

One thing is crystal clear about ditch rabbitsfoot grass – it’s a water lover! Its wetland status varies by region, but it consistently shows up in moist to wet environments:

  • In some regions like the Great Plains and Atlantic Coast, it’s considered an obligate wetland plant, meaning it almost always grows in wet conditions
  • In other areas like the Arid West and Hawaii, it’s classified as facultative wetland, usually preferring wet spots but occasionally tolerating drier conditions

Should You Plant It?

Here’s where things get interesting. While ditch rabbitsfoot grass isn’t native to North America, it’s also not considered invasive or particularly problematic in most areas. It tends to stick to disturbed, wet areas where it fills a niche without crowding out established native plants.

However, as a responsible gardener interested in supporting local ecosystems, you might want to consider native alternatives that provide similar aesthetic appeal while offering better wildlife benefits. Native sedges, rushes, or indigenous wetland grasses can give you that soft, naturalistic look while supporting local birds, beneficial insects, and other wildlife.

Growing Conditions and Care

If you do encounter this grass on your property or decide to work with it, here’s what it needs to thrive:

  • Moisture: Consistent water is non-negotiable – think pond edges, rain gardens, or areas with poor drainage
  • Sunlight: Full sun to partial shade works well
  • Soil: Adaptable to various soil types as long as they stay moist
  • Climate: Hardy in USDA zones 7-10, based on its current distribution

The grass is relatively low-maintenance once established, primarily because it naturally seeks out the conditions it needs. It self-seeds readily, so you might find new plants popping up in suitable spots around your garden.

The Bottom Line

Ditch rabbitsfoot grass is one of those plants that’s neither hero nor villain in the garden world. It’s found its place in the American landscape and generally minds its own business in wet, disturbed areas. While it won’t harm your garden, choosing native wetland plants will better support local wildlife and create a more ecologically valuable landscape.

If you’re dealing with a wet, challenging spot in your garden, consider this an opportunity to explore beautiful native alternatives like native sedges, monkey flower, or indigenous rushes that will give you that soft, naturalistic appeal while contributing to your local ecosystem’s health.

Polypogon interruptus 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. Polypogon interruptus is also known as:

Polypogon lutosus auct. non | USDA symbol: POLU5

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.

Wetland Status

The rule of seasoned gardeners and landscapers is to choose the "right plant for the right place" — matching plants to their ideal growing conditions, so they'll thrive with less care and fewer inputs. But the simplicity of this catchphrase conceals how tricky plant selection can be if you don't have the right information. While tags on nursery plants list watering requirements, there's more to the story.

Knowing a plant's wetland status can simplify the process by revealing the interaction between plants, water, and soil. You might be surprised to learn that popular landscape plants are wetland species! And what may be a wetland plant in one area, in another it might thrive in drier conditions. The table below gives insight into the preferred growing conditions of this plant throughout its geographical distribution.
