Tithonia rotundifolia is native to Mexico and Central America, thriving in sunny, open areas such as grasslands and disturbed soils. This annual plant, which can reach heights of up to 6 feet, produces vibrant, daisy-like flowers that range in color from bright orange to red. Its blooms are notable for their relatively large size, typically measuring around 3 inches in diameter, with an arrangement of ray florets surrounding a dense cluster of yellow disc florets at the center. The plant's growth habit is tall and bushy. Tithonia rotundifolia is commonly cultivated in the United States and other warm regions worldwide due to its drought tolerance and minimal care requirements. Tithonia rotundifolia has been reported to naturalize, particularly in areas with mild climates where it can persist without replanting, although it is not considered highly invasive.
