Tithonia thurberi, or Arizona Sunflowerweed, is an annual sunflower species that can grow up to 3 ft tall and is found in rich soils, often at the edges of streams and ditches, in riparian and woodland habitats between 3000-4500 ft. The smaller, yellow flowers bloom August-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.
