Mexican Sunflower (Tithonia rotundifolia) is a vibrant and fast-growing annual plant known for its brilliant orange or red-orange flowers that resemble traditional sunflowers.
Mexican Sunflowers bloom from mid-summer to early fall, producing masses of colorful flowers.
- Plant Mexican Sunflower seeds outdoors after the last frost date in your area, typically in late spring or early summer.
- Alternatively, you can start seeds indoors 4-6 weeks before the last expected frost and transplant them once they have several true leaves.
- Sow the seeds 1/4 inch (6 mm) deep in well-draining soil.
- Space the seeds or seedlings about 18-24 inches (45-60 cm) apart, as Mexican Sunflowers can grow quite tall and wide.
- The plant can reach heights of 3 - 4 feet
- Seeds usually germinate within 7-14 days.
