When were sunflowers first introduced to the US?
They were then introduced to Europe in the early 16th century and made their way to Russia. In Russia, where oilseed cultivators were located, these flowers were developed and grown on an industrial scale. Russia then reintroduced this oilseed cultivation process to North America in the mid-20th century; North America began their commercial era of sunflower production and breeding. New breeds of the Helianthus spp. began to become more prominent in new geographical areas.
What are the benefits of sunflower seeds?
The seed and sprouts of the common sunflower ( Helianthus annuus L.) have many medicinal uses. The edible seed and the sprout have an abundance of nutrients and biological activities and have many antioxidants such as phenolic acids, flavonoids and vitamins. The common sunflower has many antioxidant effects which serve as a protective function for cellular damage. Their phytochemical constituents, which include phenolic acids, flavonoids and tocopherol (vitamin E), have many potential benefits. The sunflower seed and sprout also have high concentrations of vitamins A, B, and C and are high in niacin. They also have many minerals such as calcium, potassium and iron. Sunflower seed extract contain antidiabetic effects where secondary metabolites within those extracts are able to control glucose levels effectively. The bioactive peptides of the common sunflower are known to have antihypertensive effects. Sunflower oil also helps in anti-inflammatory activity, prevents gastric damage and is a therapeutic alternative in the healing process for microscopical and clinical wounds.
Why are sunflowers growing in drier environments?
Another biotic factor that can explain for the evolution of larger sunflowers in drier environments is that the pressure from florivory and disease favors smaller flowers in habitat s that have a more moderate supply of moisture (mesic habitat).
Why do sunflowers face east?
Before blooming, sunflower plants tilt during the day to face the sun in order to gain more sunlight. This heliotropism continues for a short time when the plant blooms, young sunflower heads tracking of the sun. This is thought to help attract pollinators, as many are more attracted warm flowers. By the time they are mature, though, sunflowers generally face east. which lets them be warmed by the rising sun. The movement of sunflowers through heliotropism happens as the sunflower follows the sun, the opposite side of the sunflower stem begins to accumulate growth hormones and this causes growth which redirects the sunflower. The rough and hairy stem is branched in the upper part in wild plants, but is usually unbranched in domesticated cultivars.
Why are sunflowers beneficial to insects?
are a nectar producing flowering plant that attract pollinators and parasitoids which reduce the pest populations in nearby crop vegetation. Sunflowers attract different beneficial pollinators (e.g., honey bees) and other known insect prey to feed on and control the population of parasitic pests that could be harmful to the crops. Predacious insects are first attracted to sunflowers once they are planted. Once the Helianthus spp. reaches six inches and produces flowers it begins to attract more pollinators. Distance between sunflower rows and crop vegetation plays an important role in this phenomenon, hypothesizing that closer proximity to the crops will increase insect attraction.
What is the history of Helianthus spp?

Why are sunflowers valuable?
The common sunflower is valuable from an economic as well as from an ornamental point of view.

Where did sunflowers originate?
These crops were found in Tabasco, Mexico at the San Andres dig site. The earliest known examples in the United States of a fully domesticated sunflower have been found in Tennessee, and date to around 2300 BC. Other very early examples come from rockshelter sites in Eastern Kentucky. Many indigenous American peoples used the sunflower as the symbol of their solar deity, including the Aztecs and the Otomi of Mexico and the Incas in South America. In 1510 early Spanish explorers encountered the sunflower in the Americas and carried its seeds back to Europe. Of the four plants known to have been domesticated in eastern North America and to have become important agricultural commodities, the sunflower is currently the most economically important.
How tall are sunflowers?
The plant has an erect rough-hairy stem, reaching typical heights of 3 metres (9.8 ft). The tallest sunflower on record achieved 9.17 metres (30.1 ft). Sunflower leaves are broad, coarsely toothed, rough and mostly alternate. What is often called the " flower " of the sunflower is actually a " flower head " or pseudanthium of numerous small individual five-petaled flowers (" florets "). The outer flowers, which resemble petals, are called ray flowers. Each "petal" consists of a ligule composed of fused petals of an asymmetrical ray flower. They are sexually sterile and may be yellow, red, orange, or other colors. The flowers in the center of the head are called disk flowers. These mature into fruit (sunflower "seeds"). The disk flowers are arranged spirally. Generally, each floret is oriented toward the next by approximately the golden angle, 137.5°, producing a pattern of interconnecting spirals, where the number of left spirals and the number of right spirals are successive Fibonacci numbers. Typically, there are 34 spirals in one direction and 55 in the other; however, in a very large sunflower head there could be 89 in one direction and 144 in the other. This pattern produces the most efficient packing of seeds mathematically possible within the flower head.
How deep should sunflowers be planted?
They grow best in fertile, moist, well- drained soil with heavy mulch. In commercial planting, seeds are planted 45 cm (1.48 ft) apart and 2.5 cm (0.98 in) deep .

Sunflowers can be processed into a peanut butter alternative, sunflower butter. In Germany, it is mixed with rye flour to make Sonnenblumenkernbrot (literally: sunflower whole seed bread), which is quite popular in German-speaking Europe. It is also sold as food for birds and can be used directly in cooking and salads. Native Americans had multiple uses for sunflowers in the past, such as in bread, medical ointments, dyes and body paints.
How many chromosomes are in a sunflower?

Do sunflowers track the Sun?
A common misconception is that flowering sunflower heads track the Sun across the sky. Although immature flower buds exhibit this behaviour, the mature flowering heads point in a fixed (and typically easterly) direction throughout the day. This old misconception was disputed in 1597 by the English botanist John Gerard, who grew sunflowers in his famous herbal garden: " [some] have reported it to turn with the Sun, the which I could never observe, although I have endeavored to find out the truth of it." The uniform alignment of sunflower heads in a field might give some people the false impression that the flowers are tracking the Sun.
What are the petals of a sunflower called?
The outer petal-bearing florets are the sterile florets and can be yellow, red, orange, or other colors. The florets inside the circular head are called disc florets, which mature into seeds. The flower petals within the sunflower's cluster are always in a spiral pattern.
