My son put out bird feeders during the winter 2014-15 and the little brat birds kept pitching the sunflower seeds out onto the ground. To our dismay, some of the seeds took root and gifted us with sunflowers in front of our deck this year. We were delighted! I noticed the larger headed sunflowers did have a droopy stance while the smaller heads were erect. Watering did not seem to change the situation. I have raised the flowering types before and did not have this issue. I recently harvested the larger heads and was surprised by the weight and all the seeds these produced. Not bad for being cultivated by the birds.
