Tithonia diversifolia, commonly known as the tree marigold or Mexican sunflower, is a striking and fast-growing perennial shrub native to Mexico and Central America. This impressive plant is characterized by its tall, sturdy stems, dense clusters of vibrant orange or yellow daisy-like flowers, and large, lobed leaves. The blooms are not only visually stunning but also highly attractive to pollinators, particularly butterflies and bees. Tithonia diversifolia can reach heights of 6 to 10 feet, creating a dramatic presence in the garden or landscape. This shrub is celebrated for its adaptability and ability to thrive in a variety of soil types and climates, making it a favored choice for ornamental gardens and as a natural hedge or windbreak. With its low maintenance requirements and vibrant blooms, Tithonia diversifolia brings a burst of color and life to outdoor spaces, adding both aesthetic beauty and ecological value to gardens and landscapes. Zones 9-11GerminationTo germinate Tithonia diversifolia seeds, start by planting the seeds in well-draining soil or a seed-starting mix, burying them about 1/4 inch deep. Water the soil thoroughly after planting and maintain consistent moisture without waterlogging the soil. Place the containers in a warm location with temperatures around 20-25°C (68-77°F) to encourage germination. Tithonia diversifolia seeds typically germinate within 7-45 days under these conditions. Once the seedlings are sturdy enough to handle, they can be transplanted into individual pots or directly into the garden, where the Mexican sunflower will grow into a tall and vibrant shrub, attracting pollinators and brightening the garden with its vivid orange or yellow daisy-like flowers.
