The plant today

Urena lobata, commonly known as Caesarweed or Congo jute, is a tender perennial, variable, erect, ascendant shrub or subshrub measuring up to 0.5 meters (1.6 ft) to 2.5 meters (8.2 ft) tall. The stems are covered with minute, star-like hairs and often tinged purple. Considered a weed, it is considered to be native throughout much of the tropical and subtropical world, including South and Central America, Africa, Asia and Pacific Islands.
