Kenya Bur Grass: A Small Annual Grass You Probably Don’t Want in Your Garden

If you’ve stumbled across the name Kenya bur grass (Tragus heptaneuron), you might be wondering whether this little grass deserves a spot in your garden. Well, let me save you some time – it probably doesn’t! But understanding what this plant is and why it shows up where it does can help you make better choices for your landscape.

What is Kenya Bur Grass?

Kenya bur grass is a small annual grass that belongs to the same plant family as lawn grasses, wheat, and bamboo. True to its name, this grass produces tiny, bur-like seeds that can stick to clothing, fur, and anything else that brushes against them. It’s one of those plants that’s much better at spreading itself around than it is at looking pretty in your garden.

As an annual plant, Kenya bur grass completes its entire life cycle in just one growing season – sprouting, growing, flowering, setting seed, and dying all within a single year.

Where Does Kenya Bur Grass Grow?

Originally from Africa and parts of Asia, Kenya bur grass has made its way to the United States, where it’s currently established in South Carolina. As a non-native species that reproduces on its own in the wild, it has the potential to spread to other areas with similar climates.

Why You Probably Don’t Want to Plant It

Here’s the thing about Kenya bur grass – it’s not what most gardeners would call attractive. This little grass offers:

  • Minimal ornamental value with small, inconspicuous appearance
  • Bur-like seeds that stick to everything (including your socks!)
  • No significant benefits for pollinators since it’s wind-pollinated
  • Limited wildlife value compared to native alternatives

Since it readily reproduces on its own and spreads without human help, intentionally planting Kenya bur grass could contribute to its further establishment in new areas.

Better Native Alternatives

Instead of Kenya bur grass, consider these beautiful native grasses that will give you much more bang for your buck:

  • Little bluestem (Schizachyrium scoparium) – gorgeous fall color and excellent wildlife value
  • Buffalo grass (Poaceae americana) – drought-tolerant with great texture
  • Purple lovegrass (Eragrostis spectabilis) – delicate, cloud-like seed heads
  • Broomsedge bluestem (Andropogon virginicus) – golden fall color and bird-friendly seeds

If You Encounter Kenya Bur Grass

If you find Kenya bur grass growing in your yard or garden, it’s likely arrived on its own rather than being intentionally planted. Since it’s an annual, preventing it from setting seed will help reduce future populations. Simply pull or mow the plants before they develop their characteristic burs.

The good news? Since it’s an annual, consistent management can effectively control Kenya bur grass populations over time.

The Bottom Line

While Kenya bur grass isn’t necessarily harmful, it’s not adding much value to your garden either. Your time, energy, and garden space are better invested in native grasses that will support local wildlife, look more attractive, and contribute to a healthier ecosystem. Save the exotic grasses for species that really earn their keep – this little bur-maker just isn’t one of them!
