This perennial native North American superstar sunflower is hardy in all USDA zones. It grows in a wild, prairie pattern and pops back up year after year, spreading rhizomatically. These are amazing multifunctional landscaping plants that can reduce erosion with their dense root system, contain grass areas as a border due to their alelopathic chemicals, bioremediate (filter toxins out of) water and soil, foster wildlife habitat, feed humans and look beautiful!
 
With their bright yellow, daisy-like flowers and tall, slender stems, they can grow up to 8 feet tall, making a stunning addition to any garden. To plant, sow the seeds directly into the ground in late spring or early summer, in a location with full sun and well-drained soil. Water regularly and provide support for the tall stems as they grow. Maximilian Sunflowers are low-maintenance and attract pollinators such as bees, butterflies and birds to your garden.
