Gambian Dayflower: A Little-Known Annual for Florida Gardens

Meet the Gambian dayflower (Commelina nigritana var. gambiae), a modest annual that’s quietly made its way into Florida’s plant community. While it might not be the showstopper of your garden, this little forb has an interesting story and some unique characteristics worth exploring.

What Exactly Is Gambian Dayflower?

The Gambian dayflower belongs to the spiderwort family and is classified as a forb—essentially a soft-stemmed plant without woody tissue. Think of it as the botanical equivalent of that friend who’s low-maintenance but always reliable. As an annual, it completes its entire life cycle in one growing season, making it a temporary but potentially charming addition to your landscape.

You might also see this plant referenced by its synonym, Commelina gambiae C.B. Clarke, in older botanical texts, but don’t let the name confusion fool you—it’s the same plant.

Where You’ll Find It

Currently, the Gambian dayflower has established itself in Florida, where it reproduces on its own in the wild. This non-native species originally hails from other regions but has found Florida’s climate to its liking.

Should You Grow Gambian Dayflower?

Here’s where things get a bit tricky. While this plant isn’t currently listed as invasive or noxious, there’s limited information available about its garden performance, wildlife benefits, or potential ecological impact. This makes it something of a wild card in the gardening world.

If you’re considering adding it to your landscape, here are some factors to weigh:

  • It’s an annual, so any mistakes won’t be permanent
  • As a non-native species, it won’t provide the same ecosystem benefits as native plants
  • Limited information makes it difficult to predict its behavior in your garden

Better Alternatives for Florida Gardeners

Since information about Gambian dayflower is sparse, you might want to consider some well-documented native alternatives that offer similar characteristics:

  • Native spiderworts (Tradescantia species) for similar foliage texture
  • Florida native wildflowers for annual color and wildlife benefits
  • Other native forbs that support local pollinators and wildlife

The Bottom Line

While the Gambian dayflower might intrigue the adventurous gardener, the lack of available information about its garden performance and ecological impact makes it a bit of a gamble. If you’re set on trying something unusual, proceed with caution and keep an eye on how it behaves in your specific location.

For most gardeners, especially those interested in supporting local ecosystems, focusing on well-documented native plants will provide more predictable results and greater environmental benefits. After all, why take a chance on a plant mystery when Florida offers so many beautiful, proven native alternatives?

Remember, successful gardening often comes down to choosing plants that are well-suited to both your local conditions and your gardening goals. With the Gambian dayflower, you’d be working with more questions than answers—and in gardening, that’s not always the most comfortable place to be.
