The sunflower seed is the fruit of the sunflower (Helianthus annuus). The term "sunflower seed" is actually a misnomer when applied to the seed in its pericarp (hull). Botanically speaking, it is more properly referred to as an achene. When dehulled, the edible remainder is called the sunflower kernel or heart.
There are three types of commonly used sunflower seeds: linoleic (most common), high oleic, and NuSun. Each variety has its own unique levels of monounsaturated, saturated, and polyunsaturated fats. The information in this article refers mainly to the linoleic variety.
For commercial purposes, sunflower seeds are usually classified by the pattern on their husks. If the husk is solid black, the seeds are called black oil sunflower seeds. The crops may be referred to as oilseed sunflower crops. These seeds are usually pressed to extract their oil. Striped sunflower seeds are primarily used for food; as a result, they may be called confectionery sunflower seeds.

Famous quotes containing the words sunflower and/or seed:
“When van Gogh paints sunflowers, he reveals, or achieves, the vivid relation between himself, as man, and the sunflower, as sunflower, at that quick moment of time. His painting does not represent the sunflower itself. We shall never know what the sunflower itself is. And the camera will visualize the sunflower far more perfectly than van Gogh can.”
—D.H. (David Herbert)
“Not one man is forgiven! East, West, North, South!
I bite off their dingbats. Christ rots in my mouth.
I curse the seed of my father that put me here
for when I die there’ll be no one to say: Oh No!
Oh dear.”
—Anne Sexton (1928–1974)
