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.
Pollination occurs by insect, bird, wind, humans, or other natural mechanisms. Because there are no restrictions on the flow of pollen between individuals, open-pollinated plants are more genetically diverse. However, as long as pollen is not shared between different varieties within the same species, then the seed produced will remain true-to-type year after year.
Annual plants are plants with a life cycle that lasts only one year. They grow from seed, bloom, produce seeds, and die in one growing season. They then need to be replanted each spring.
