Digitaria setivalva: An Elusive Grass Species
If you’ve stumbled across the name Digitaria setivalva in your plant research, you’re likely wondering what exactly this grass species is all about. Well, you’re not alone in your curiosity – this particular species presents quite the botanical mystery!

What We Know (And Don’t Know)
Digitaria setivalva belongs to the grass family (Poaceae) and goes by the common name crabgrass. However, here’s where things get interesting – or rather, frustratingly vague. Despite extensive searching through botanical databases and native plant resources, reliable information about this specific species is remarkably scarce.
The Mystery of Identity
In the world of plant taxonomy, names can sometimes be tricky. What we’re dealing with here might be:
- An extremely rare or locally endemic species
- An outdated botanical name that’s been reclassified
- A synonym for another, more commonly recognized Digitaria species
- A regional variant that hasn’t been well-documented
Geographic Distribution
Unfortunately, the geographic range and native status of Digitaria setivalva remain unclear based on available information. Without reliable distribution data, it’s impossible to determine where this grass naturally occurs or whether it would be appropriate for native gardening projects.
Should You Grow It?
Here’s the honest truth: with such limited information available, it’s difficult to recommend either for or against growing Digitaria setivalva. We simply don’t have enough reliable data about:
- Its native range and status
- Whether it has invasive tendencies
- Its specific growing requirements
- Its ecological benefits or drawbacks
- Its aesthetic qualities
Better Alternatives
If you’re looking for native grass species to add to your landscape, consider exploring well-documented Digitaria species or other native grasses in your area. Your local native plant society or extension office can provide reliable recommendations for grasses that will thrive in your specific region while supporting local ecosystems.
A Word of Caution
Given the uncertainty surrounding this species, if you do encounter plants labeled as Digitaria setivalva, proceed with caution. Without clear information about its growth habits and potential invasiveness, it’s best to stick with well-known, documented native species for your gardening projects.
The Bottom Line
Sometimes in the plant world, we encounter species that remain tantalizingly mysterious. Digitaria setivalva appears to be one of those cases where more research is needed before we can make informed gardening recommendations. Until more reliable information becomes available, your best bet is to focus on the many wonderful, well-documented native grasses that can bring beauty and ecological value to your landscape.
