Sunflower seeds are very easy to grow. I have grown them for a few years for looks, but being a very experimental gardener, I plan this year on growing them to semi-support my tomato plants. I have a few varieties but have chosen the Giant Russian variety to take on this job. They not only look great in the vegie patch, they attract bees and produce lots of seeds (for eating). I'll just have to watch it that the birds will help themselves to the seeds (and the tomatoes).
