Sunflower Seeds

Sunflower seeds are technically the fruits of the sunflower plant (Helianthus annuus)

The seeds are harvested from the plant's large flower heads, which can measure more than 12 inches (30.5 cm) in diameter. A single sunflower head may contain up to 2,000 seeds

There are two main types of sunflower crops. One type is grown for the seeds you eat, while the other — which is the majority farmed — is grown for the oil

The sunflower seeds you eat are encased in inedible black-and-white striped shells, also called hulls. Those used for extracting sunflower oil have solid black shells.

Sunflower seeds have a mild, nutty flavour and a firm but tender texture. They're often roasted to enhance the flavour, though you can also buy them raw. Healthline
