Exactly how it became Florida tasselflower eludes us completely, though were sure there is a reasonable or semi-reasonable explanation. According to the Invasive Species Compendium, it began its worldwide journey in the late 19th century, likely spreading first to the United States and Caribbean. Perhaps Florida was its first stop. It is found throughout the state but mainly from the central Peninsula south into the Keys. It's also found in Georgia, Louisiana, Texas, California, plus Puerto Rico and the Virgin Islands.
The flower is a striking red, resembling a barber's shaving brush, which is the inspiration for several of its other common names. It is on the smallish side given the size of the plant. — it can be two to three feet tall.The flowers sit atop a long, thin stem, each stem having multiple blooms. It is an annual plant, long and gangly, either upright or leaning. The leaves are narrow, arranged alternately on the stem, arrow shaped and both lobed (each lobe coming to a sharp point) and serrated. Seedheads are dandelionesque fluffy white balls that scatter with the wind. And Florida tasselflower is a prolific seed producer — a single plant can produce as many as 5,000 potential offspring in a season.

Butterflies will frequent this plant for the nectar, as will bees. The cinnabar moth (rarely found in the U.S.), uses it as a host plant.
