Native to South America, but introduced to Hawaii
A perennial shrub that reproduces from seeds. This attractive plant grows as dense stands of tall shrubs in pastures and rangelands as well as along roadsides and in disturbed areas.
Mature plants grow to 8 feet in height, and have a much-branched and shrubby appearance with dense foliage. The stems are woody and fibrous when broken. The leaves are ovate to heart-shaped and from 3 to 5 inches long. Their tips are pointed and elongated and their margins are serrate to slightly scalloped. Leaves are hairy on both surfaces, especially on the lower surface, and the leaves occur on a stalk that may be 2 to 3 inches long as well. The large orange flowers also occur on a long, thin stalk, singly or sometimes two flowers, and the stalk has a joint in it about 2/3 of the way along. These arise from the leaf axils. The seed pod that forms is a round capsule about 1 inch in diameter, consisting of a whorl of about 10 units, each containing several seeds.
Characteristicts Important to Control:
Plants may be killed using a systemic herbicide, but they are so large that physical removal may be needed following their death, in order to open up the area.
