1.Tithonia — Overview

Tithonia — Main Image

Tithonia rotundifolia, commonly known as Mexican Sunflower or Torch Flower, is a vibrant annual plant belonging to the Asteraceae family. Native to Mexico and Central America, it is celebrated for its striking, large, daisy-like flowers with brilliant orange or red-orange petals and a yellow center. Growing vigorously, it can reach heights of 4 to 6 feet (1.2-1.8 meters) or more, forming bushy clumps with velvety, deeply lobed leaves.

Its rapid growth and spectacular blooms make it a popular choice for cottage gardens, borders, and as a dramatic focal point, attracting a plethora of pollinators, especially butterflies and hummingbirds, throughout its long blooming season from summer to frost. This resilient plant thrives in sunny, warm conditions and is relatively drought-tolerant once established.
