Sunflower “whole seeds” (fruits) are sold as a snack, after baking fry, with or without added salt. Sunflowers can be made into an alternative to peanut butter, suncake. In Germany, it is mixed with rye flour to form sunflower seed bread, which is very popular in German-speaking Europe. It is also sold as food for birds and can be used directly in cooking and salads. Sunflower oil extracted from the seeds is used for cooking, as a carrier oil, and to make margarine and biodiesel because it is cheaper than olive oil. There are a number of sunflower varieties with different fatty acid compositions; Some “high oleic” types contain higher levels of healthy monounsaturated fats in their oil than olive oil. Helianthus annuus is a species of plant in the Asteraceae family. The stem of the flower can reach 3 meters in height, with a flower head up to 30 cm wide. Other types of sunflowers include the California royal sunflower, which has a burgundy (red + purple) flower head. The wood sunflower is a native perennial herb of the aster family that can grow up to 5 to 7 feet tall.
It is native to eastern and central North America and is found in all parts of North Carolina in rocky or sandy forests and dry open places. The leaves are opposite with a smooth to slightly toothed edge and a hairy underside. The leaves often do not have a stem. Large yellow flowers do not ripen until early summer and continue until early autumn. The meal remaining after processing the seeds into oil is used as animal feed. Some recently developed varieties have hanging buds. These varieties are less attractive to gardeners who grow flowers as ornamentals, but attractive to farmers because they reduce bird damage and losses due to certain plant diseases. Sunflowers also produce latex and are being experimented with to improve their suitability as an alternative plant to hypoallergenic rubber production. Traditionally, several Native American groups planted sunflowers on the northern edges of their gardens as the “fourth sister” of the more familiar combination of corn, beans, and pumpkin.  Annual species are often planted for their allelopathic properties. [source?] However, for commercial farmers who grow staple crops, sunflower, like any other unwanted plant, is often considered a weed.
Especially in the Midwestern United States, wild (perennial) species are often found in corn and soybean fields and can negatively impact yields. Sunflower can also be used to extract toxic ingredients such as lead, arsenic and uranium from the soil. They were used to remove uranium, cesium-137 and strontium-90 from the soil after the Chernobyl disaster (see phytoremediation). The petals of the sunflower group are always spiral. In general, each flower is aligned approximately by the golden angle of 137.5° with respect to the next, creating a pattern of interconnected spirals, where the number of left spirals and the number of right spirals are consecutive Fibonacci numbers. Typically, there are 34 spirals in one direction and 55 in the other; On a very large sunflower, there could be 89 in one direction and 144 in the other.   Forest sunflower is easy to grow in moderately well-drained soil in partial shade. It is tolerant to a variety of soil types. Use in domestic garden/pollination species, natural area or forest garden.
It is drought tolerant once established. It is a high-quality wild plant. Sunflower is the flower of the state of Kansas. That`s why Kansas is sometimes called the Sunflower State. To grow well, sunflowers need full sunshine. They grow best in fertile, moist, well-drained soil with plenty of mulch. In commercial plantations, seeds are planted 45 cm (1.5 ft.) apart and 2.5 cm (1 inch) deep. Sunflowers typically grow between 1.5 and 3.5 m (5 to 12 ft) tall. The tallest sunflower confirmed by Guinness World Records measures 9.17 m (2014, Germany).
In 16th century Europe, the record was already 7.3 m (24 ft, Spain).  Most varieties are variants of H. annuus, but four other species (all perennial) are also domesticated. These include H. tuberosus, the Jerusalem artichoke that produces edible tubers.

The central flowers resemble the center of a normal flower, Apseudanthium.
The advantage for the plant is that it is very easily visible to insects and birds that pollinate it and produce thousands of seeds. The outer flowers bearing petals are the sterile flowers and can be yellow, red, orange or other colors. The flowers inside the circular head are called disc flowers that ripen into seeds.
