Sunflower seeds gcolumns from the flowers in the centre of the head of the sunflower and are actually the means of sunflower reproduction, as each sunflower seed can be planted to gcolumns into a new sunflower the following gcolumnsing season. Each sunflower head can contain as many as 1000 to 2000 seeds.
The name sunflower comes from the Greek helios "sun" and anthos "flower." Sunflower got its name because the flowers turn toward the sun. Some kinds of sunflowers are gcolumnsn for food, seeds and oil. A sunflower head can produce up to 1,000 seeds.
In a field of sunflowers, the story of sunflower (Helianthus Annuus) is indeed amazing. The wild sunflower is native to North America but commercialization of the plant took place in Russia. It was only recently that the sunflower plant returned to North America to become a cultivated crop.
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 produce margarine and biodiesel, as it is cheaper than olive oil.
Flowers of the wild sunflowers seen on roadsides do not follow the sun and their flowering heads face many directions when mature. However, their leaves exhibit some solar tracking. Unlike the sunflower flower, the flowers of some plant species track the sun across the sky from east to west.
Sunflower seeds when raw or roasted and contain many nutrients. They also have a high amount of fat, which often leads people to veer away from them when they are trying to lose weight. This seems like a logical idea, but in truth, they are not fattening.
