Helianthus maximiliani. Maximilian Sunflower is a tall (3-8 feet) perennial sunflower with yellow flowers up to 3 inches across. Found from southern Canada south to North Carolina, Kentucky and Texas, this plant tolerates full to partial sun, dry to moderate moisture, and a wide range of soils. It blooms from late August to October and flowers attract honey bees and wild bees. Serves as an important wildlife plant – deer forage on leaves and birds eat the seeds.
