• Mammoth Russian Sunflower is a Huge plant and Flower. They can get 10 to 15 feet tall, but most get about 10-12 ft. They have huge leaves, and a thick, sturdy stalk that will produce a giant 12-16" feathery yellow flower with hundreds of seeds. The seeds are ready when the flower nods and drops its petals. Easy to grow from seed. Pretty much a carefree, drought tolerant plant once the seedlings are established. Water once or twice a week if no rain. Over-watering can cause disease. A little slow-release organic fertilizer will increase seed production. 50+ Organic seeds from Kansas per order. Thank You!.
