Mexican Sunflower (Tithonia rotundifolia) dazzles the garden with brilliant orange-red blooms that stand tall above lush green foliage, creating a bold display of color from midsummer until frost.

🌱 Planting Instructions 

In areas that experience winter or frosts, plant wildflowers in the spring, after all danger of frost has passed. Locations that do not receive frosts can plant wildflowers anytime.

Sow seeds in fields, gardens, lawns, and meadows. Cleared, open spaces will grow more flowers.

Choose a planting day that has rain in the near future, so you don't have to water them. Plant them in full sun in an area that has good drainage. Scatter the seeds broadly around the space. Walk over the seeds to press them into the ground. Do not bury them; they need the sun to germinate.

Keep the soil moist without being soaked until they are 4-6” high. After that, natural rain is generally sufficient.
