African Finger Millet: What You Need to Know About This Non-Native Grass
If you’ve stumbled across the name African finger millet (Eleusine coracana africana de) in your gardening research, you’re looking at an interesting annual grass that’s made its way into parts of the United States. This non-native plant has established itself in the wild, but there’s quite a bit we still don’t know about its garden potential.
What Exactly Is African Finger Millet?
African finger millet belongs to the grass family and falls into that broad category of graminoids – basically grass and grass-like plants including true grasses, sedges, and rushes. As an annual, it completes its entire life cycle in one growing season, from seed to seed.
You might also see this plant referenced by its scientific synonyms:
- Eleusine africana Kennedy & O’Byrne
- Eleusine indica (L.) Gaertn. ssp. africana (Kennedy & O’Byrne) S.M. Phillips
Where Does It Grow?
Currently, African finger millet has been documented growing wild in California and South Carolina. As a non-native species, it reproduces on its own without human intervention and appears to be persisting in these areas.

Should You Plant African Finger Millet?
Here’s where things get a bit tricky. While this grass isn’t currently listed as invasive or noxious, we simply don’t have enough information about its garden behavior, growing requirements, or potential ecological impacts. Sometimes that uncertainty is reason enough to pause.
What we do know is that it’s already reproducing spontaneously in the wild, which means it’s found conditions it likes in at least two very different climate zones. However, without clear data on its growth habits, preferred conditions, or wildlife benefits, it’s hard to recommend it for intentional cultivation.
Consider Native Alternatives
If you’re drawn to the idea of growing annual grasses in your garden, consider exploring native options instead. Native grasses offer several advantages:
- They’re adapted to local conditions and typically easier to grow
- They provide known benefits to local wildlife and pollinators
- They won’t pose potential invasive risks to local ecosystems
- They help support the natural biodiversity of your region
Your local native plant society or cooperative extension office can point you toward annual grasses native to your specific area that might scratch the same gardening itch.
The Bottom Line
African finger millet remains something of a mystery in the gardening world. While it’s not flagged as problematic, the lack of information about its cultivation requirements, ornamental value, and ecological role makes it difficult to recommend. When in doubt, native plants are usually the safer and more beneficial choice for both your garden and the broader environment.
If you do encounter this grass growing wild in your area, it’s worth reporting your observation to local botanical surveys – every bit of data helps scientists better understand how non-native species are establishing themselves in our landscapes.
