Sunflower seeds are edible. 

Eat the seeds raw, or season and roast for added flavor. There are countless benefits to adding them to your bread recipes, salads, and sandwiches. Sunflowers are known for their delicious seeds and perhaps the lesser-known fact is you can eat the entire sunflower; stalk, leaves, petals, and seeds. 


Sunflowers attract pollinators and beneficial insects into your vegetable garden, improving the pollination of your fruits and vegetables. They provide a healthy source of nectar and pollen for the bees. Birds love the seeds and it's fun to watch them swing themselves upside down on the flowers to harvest the seeds. Chickens and livestock eat sunflower seeds for supplemental food in the winter.


Eating sunflower seeds benefits your health in many ways. They are a good source of fiber and protein, and a dozen essential vitamins and minerals, two of them being zinc and selenium. The sunflower heads follow the sun each day from east to west and cast a shadow where they grow. This shade provides an excellent opportunity to plant and grow lettuce and spinach and other plants that will bolt in the full heat of the sun. Planting sunflowers can also provide a living trellis for other crops in the garden like peas. Their stem is also strong enough to make paper and the petals and seeds have natural dying properties.
