There are about 150 different species of flowering plants in the Lantana genus, all in the verbena family (Verbenaceae). Some are shrubs, some are spreading and low-growing.
The flower clusters are called umbels, and are typically a mix of yellow, orange and red florets. The flowers change color as they mature, and the tiny flower clusters often have 2 or 3 colors during the flowers’ display.
These hardy flowers can be nice low shrubs, or ground cover, depending on the species you have.
