Cosmos originally comes from Mexico in the Americas and belongs to 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. They have feathery deeply lobed leaves. The flower heads are solitary, with a diameter of 3-6 centimeters. The ray florets are purple, pink, or white; the舌-shaped petals are elliptical-obovate, and the seeds are black and purple, with a long beak at the top and 2-3 spines. Cosmos is a famous ornamental plant and is widely cultivated in our country, with its beautiful presence seen by roadsides, field ridges, and streamsides.
Cosmos can be propagated by sowing seeds or by cutting. Sowing: In the northern part of China, it is usually sown 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 the ability to self-sow, so once planted, there's no need to plant them every year. Cutting: Cosmos is cut in May, selecting robust top branches, cutting an 8 to 10 cm long section as a cutting, and planting 3 to 5 cuttings in a cluster in prepared soil, with 4 to 5 cm above the ground. Watering and shading are applied, and roots will form in about half a month. With proper care, flowers will bloom soon.
Cosmos has a strong vitality, loves sunlight, and is drought-resistant and adaptable to poor soil. It is not demanding on soil, but cannot be waterlogged. If planted in fertile soil, it can cause excessive growth of branches and leaves, which may affect the quality of flowering. To maintain the overall beauty of the plant, it is necessary to pinch the tips of cosmos multiple times during its growing period, which can矮化 the plant and encourage branching to increase the number of flowers.
