Has anyone ever saved the seeds from their sunflowers, let them dry out and replant them? One year, I wondered, if this was really possible. So, I gave it a try and low and behold new sunflowers starting popping up! I was so proud of myself for saving money, and the kids just loved how fast the sunflowers shoot up. It usually just takes about a week to see the sprouting action begin. Just make sure, you grab a stick or something to help prompt up the sunflower or can fall over easily.
