Also called Mexican sunflower. Years ago, I planted a wildflower mix, and the planting was soon dominated by 4-foot tall plants with single, reddish-orange flowers. I never was able to figure out what the flower was until I happened upon a similar planting at the Olbrich Gardens in Madison, Wisconsin. It was tithonia. The tall plants have attractive, soft green foliage with a fairly large number of bright 4″-5″ blooms. I find this very striking, especially as a backdrop plant to other vivid colored annuals like zinnias and calendula.
