That field of sunflowers sounds so beautiful. Occasionally I've passed by sunflower fields here in KY and I always have to stop and just stare at them for awhile. I do love sunflowers. I'm not sure why your seeds don't grow like the pictures show. Maybe we just don't know what has been done to the seeds. I've never had them to grow terribly tall or en masse for me either but sometimes I think I just didn't plant them early enough.
