Aztec Maximilian Sunflower is a native, warm season perennial forb that grows 3-9’ tall from a large underground tuber. Maximilian Sunflower is found throughout the state except for the Trans Pecos and South Texas Plains. It is useful as forage for all types of livestock and many species of wildlife. Seeds are eaten by many bird species, although they are not a preferred food of most game birds. The species has also been considered to have potential use as a biofuel source. Pollinators relish the showy yellow blooms and the plant provides an important late summer through autumn nectar source across Texas, particularly for migrating monarchs.
