Its native home is apparently central Mexico, although it has become naturalized in many other places (North and South America, Europe, Japan, Philippines, the northern India, Nepal, etc.).

The petioled leaves are ovate and serrated are opposite branching, and covered coarse, hispid[6] hairs.

[7] The small flower heads are up to a centimeter wide (0.4 inches) but typically 2-3mm in diameter and have rounded center filled with many disc florets usually in a shade of bright yellow.

Both the disk and ray florets are fertile[7] producing an achene with a large pappus.

Care must be taken to not confuse them with the distantly related, and visually similar, Tridax procumbens.
