Super Giant Sunflower 10 seeds

Mongolian giant reaches up to 14ft tall with one of the largest flowering sunflower seed heads available. These can achieve up to 18in across. From my experience the plants will need support though in windy conditions because of the very heavy heads. I also learnt to harvest them early if you want the seeds as they are a favourite of many birds!!
