Our most popular variety, this is the classic sunflower with enormous 25-30cm (10-12”) wide flower heads comprised of bright yellow petals and dark chocolate centers. These stately plants grow quite tall, averaging 180-240cm (6-8’) in height, but if watered and fertilized frequently and planted in excellent deep soil, they have been known to top 360cm (12’)!
