Tithonia, often referred to as 'Mexican Sunflower', typically requires ample sunlight and moderate watering. The species thrives best in temperatures of 20-30°C, in well-draining, fertile soil. Common challenges for tithonia include susceptibility to pests like aphids and whiteflies, as well as mildew and rust diseases. While relatively hardy, these plants may require some winter protection in colder climates. Seasonally, these sun-loving plants actively grow in summer and should be deadheaded regularly for flourishing blooms.
