About Sunflower seeds
Wikipedia Article About Sunflower seeds on Wikipedia
The sunflower seed is the seed 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'.
For commercial purposes, sunflower seeds are usually classified by the pattern on their husks. If the husk is solidly black, the seeds are called 'black oil sunflower seeds'. The crops may be referred to as 'oilseed sunflower' crops. These seeds are usually pressed into sunflower oil. Additionally, these seeds are generally considered the seed of choice for bird feeders.
If the husks are striped, the seeds are called 'striped sunflower seeds' or 'stripers'. Due to their lower oil content, the crops are called 'non-oilseed sunflower' crops. Striped sunflower seeds are primarily used for food; as a result, they may also be called 'confectionery' sunflower seed.
