Sunflowers were revered among native Americans and used as medicine and food sources. They are still very popular today. Basic guidelines for growing them include using rich, well-drained, alkaline-to-neutral soil in a location that receives 5-8 hours of sunlight.
Water must be consistent, and give the soil around it nitrogen-rich fertilizer every 2 weeks. The tallest sunflower on record was grown in 2014 in Germany, reaching 30 feet!
