Sunflower: The flower that follow the sun.

A classic yellow flowers, the one we love to see when there is a field full of them, as a crop they can be produce as edible oil and fruits is also used as wild bird food, Sunflower was a common crop among the American Indian tribes of North America. Archaeological studies place crops of this plant in Arizona and New Mexico around 3,000 BC; some archaeologists suggest that the sunflower may have been cultivated before the corn.

The sunflower is the joy of summer with its rotation looking at the sun. It is an annual plant that is grown for seed in early March and blooms in summer or early fall.

The beauty of sunflowers

The sowing season for rainfed crops last approximately one month from the beginning of summer.Although it prefers clay soils, it is essential that the soil has good drainage.The waterings must be moderate and, thanks to its deep root, it can access a greater amount of water from the soil.

Everyone knows that sunflowers, every morning, begin to turn following the west path of the sun.However, recent studies have shown that once the flowers mature, the sunflowers slow their daily movement until they are fixed facing east.

When growth of the flower stalk to the sun stops and the flower is mature. This eastward orientation allows rapid warming in the morning and, as a result, increase pollinator visits.it can reach six meters in height, although, the normal thing is that it measures between two or three meters.

In culture:

The sunflower is the state flower of the US state of Kansas, and one of the city flowers of Kitakyūshū, Japan.

The flowers were the subject of Van Gogh’s Sunflowers series of paintings.

Sunflowers were also worshipped by the Incas because they viewed it as a symbol for the Sun.

During the late 19th century, the flower was used as the symbol of the Aesthetic .

Threats and diseases:

One of the major threats that sunflowers face today is Fusarium, a filamentous fungus that is found largely in soil and plants.

Downy mildew is another disease to which sunflowers are susceptible. Its susceptibility to downy mildew is particular high due to the sunflower’s way of growth and development. Sunflower seeds are generally planted only an inch deep in the ground.

Another major threat to sunflower crops is broomrape, a parasite that attacks the root of the sunflower and causes extensive damage to sunflower crops, as high as 100 percent.

The seed and sprouts of the common sunflower 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. In today’s market, most of the sunflower seeds provided or grown by farmers are hybrids. Hybrids or hybridized sunflowers are produced by crossbreeding different types and species of sunflower.

If you want your sunflower bouquets to be kept for as long as possible, we recommend you to  always use a vase with room temperatura, cut the stem diagonally with clean scissors or pruning knives, make sure the leaves do not touch the water. Also do not place the vase with the sunflowers in full sun, near heat sources or drafts. Sunflowers requires a lot of water make sure you constantly refilling their base. Do not place the sunflowers near a fruit bowl as the gases emitted by the fruit make the flowers wither faster.

Sunflowers are not just pretty flowers, they are also extremely good at absorbing toxins as an example millions of sunflowers were planted after the devastating tsunami that destroyed the reactors at the Fukushima nuclear power plant in Japan and were used to treat the land near the Chernobyl nuclear power plant.
