There are about 70 different species of sunflower in the genus. These sunflower species can be divided into three categories: giants, colored sunflowers, and dwarf sunflowers.
Sunflowers were discovered in the Americas for the first time. They were domesticated in Mexico and the United States' southern states. Some of the earliest sunflower seeds have been discovered in Mexico, dating back to 2100 BCE. Sunflowers were known to be grown by native American tribes as a valuable crop.
Native Americans, Aztecs, and Incas all revered the sunflower as a symbol of solar deities.
Green organizations also use the sunflower as a symbol. The sunflower is used as a symbol of the vegan society, as well as being adopted by eco-conscious people.
Sunflowers are tall perennial plants that can live for a year or more. Sunflowers can reach a height of 300 cm in some cases (some even longer than this). Their flower heads are large and white, with maroon florets inside.
The outside of the flower is colored in a variety of hues. Sunflowers come in a variety of colors, including red, cream, orange, bronze, and purple, despite the fact that they're traditionally thought to be yellow.
Sunflowers turn to face the Sun as they grow in order to gain more energy. This rotating, known as heliotropism, stops as they begin to bloom. The sunflower will face east when it is fully mature. Sunflowers with undomesticated varieties have coarse stems that branch at the top.
Growth & Maintenance
Sunflowers are a type of plant that is native to the Americas and lives for a long time. A sunflower's growth is influenced by its surroundings as well as its genetic makeup.
Sunflowers are also influenced by the season in which they begin to grow; this has a significant impact on how they develop. The dormant and reproductive stages of the plant can be used to sort the growth of different sunflowers. By looking at the tops of the sunflower branches, these stages can be identified.
Sunflowers, as their name implies, are sun-loving plants that thrive in long, hot summers. Their soil must be sufficiently moist while also being well-drained. Sunflowers can grow in drier conditions as well, but it is not ideal for their growth.
Sunflowers must be handled differently depending on how long they live. Seeds for annual sunflowers should be planted in late winter if grown indoors. If you're going to grow them outside (or dealing with perennials), spring is the best time to do so.
Some of the threats to sunflowers include various types of mildew, rust and fungal leaf spots. Beetles and caterpillars are also active predators of sunflowers.
