Tithonia rotundifolia, or Mexican Sunflower, is an annual sunflower species that can grow up to 6 ft tall. This native to Mexico has deep orange flowers that bloom May-October and are pollinated by native bees. It is also a larval host plant for butterfly and moth species, and its seeds provide food for birds and other wildlife. Plant in full sun to partial shade in well-draining soil, and remove spent flowers regularly to prolong life. It does very well when planted with the monsoons.
