The Riesen Sonnenblumenkerne, or Giant Sunflower, is a remarkable plant that produces towering sunflowers with large, bright yellow blooms. These impressive flowers can reach heights of up to 10 feet, making them a showstopper in any garden. Known for their stunning visual appeal, these heirloom seeds are perfect for creating a focal point in flower beds, as well as attracting pollinators like bees and birds.
Water regularly to keep the soil consistently moist, especially during the growing season. Once established, sunflowers are somewhat drought-tolerant, but occasional deep watering encourages stronger growth.
