The Kong Sunflower is a very tall growing sunflower--about 14 to 17 feet; but this variety has multiple blooms and branches. Plant in an area that gets full sun, and if possible, a windbreak because the tall ones like to blow over. This garden seed takes 75 plus days. It grows fast and takes 5 to 10 days to germinate. Add some style to your garden today; the Kong is a great addition to any line up! Happy growing!!!
