Tilesia baccata, commonly known as Mexican Sunflower, Japanese Sunflower, or Tree Marigold, is a fast-growing perennial herb native to Central America and South America. It thrives in a variety of habitats including tropical forests, open areas, disturbed soils, and roadsides. This species is adaptable to a range of ecological conditions but is particularly common in areas with a history of disturbance. Tilesia baccata can reach a height and width of 6-10 feet (1.8-3 meters), displaying a bushy, upright habit. Its large, bright yellow flowers are showy and bloom prolifically from summer into fall, attracting pollinators such as bees and butterflies.

The Mexican Sunflower is valued for its vibrant flowers and rapid growth, making it an excellent choice for creating visual impact in a short period. It is often used in tropical and subtropical gardens as a specimen plant, for screening purposes, or in borders. It requires full sun to flourish and prefers medium or fast-draining loam or sandy soils. While it tolerates a range of soil conditions, it performs best with regular watering. However, it is drought-tolerant once established. Tilesia baccata can be invasive outside its native range, so it is essential to consult local guidelines before planting.CC BY-SA 4.0
