| Identification | This is an annual herb with spreading to mostly erect stems that root at some nodes. Most plants grow 2 feet long or less, with opposite, lance-shaped, toothed leaves. Heads are very small (less than 1/3-inch across), with numerous dull whitish rays 2-2.5 mm long. The plant often appears weedy, somewhat like an exotic species, though it clearly is a native one. It looks like no other species, composite or otherwise, when in bloom -- as it is the only member of its genus in the Eastern states. | |
| Taxonomic Comments | A synonym is Eclipta alba.
| |
| Other Common Name(s) | Yerba-de-Tajo (often spelled as Yerba-de-tago). This name is often used, but thankfully False Daisy is a good and alternate common name. | |
