Cosmos is native to Mexico, America, and is a plant of the Asteraceae family, cosmos genus. It is an annual or perennial herb, with a height of 1-2 meters. The roots are spindle-shaped with many fibrous roots, and the base of the stem has adventitious roots. The stems are usually erect and can sway with the wind. It has feathery deeply lobed leaves. The capitulum is solitary, with a diameter of 3-6 centimeters. The ray florets are purple, pink, or white; the ligules are elliptical and obovate, the seeds are black and purple, with a long beak at the top, and have 2-3 spines. Cosmos is a famous ornamental plant and is widely cultivated in China, with its beautiful figure seen by the roadside, field ridges, and riverbanks.
Cosmos can be propagated by seed sowing or cutting. Seed sowing: In northern China, sowing is usually done from April to June, with flowers blooming from June to August. If sown in July to August, it can bloom in October, with shorter and tidier plants. Cosmos seeds have self-sowing ability, so once planted, there is no need to plant them every year. Cutting: Cosmos cuttings are done in May, selecting sturdy top branches, cutting an 8 to 10 cm long section as cuttings, and inserting 3 to 5 plants in a cluster into prepared soil, with 4 to 5 cm exposed above the ground. Watering and shading are done, and roots will form in about half a month. With proper care, they will soon bloom.
Cosmos has a robust nature, loves sunlight, and is drought-resistant and can tolerate poor soil. It is not picky about soil but cannot accumulate water. If planted in fertile soil, it may cause the branches and leaves to grow excessively, which can affect the quality of flowering. To maintain the overall beauty of the plant, multiple pinching is required during the growth period of cosmos, which can make the whole plant shorter and encourage branching, increasing the number of flowers.
