The bedding plant, herbaceous plant, and garden plant seem to refer to three different types of ornamental plants. However, in fact, there is only one meaning that they express: "Cultivated outdoors. For ornamental, annual or perennial herbs." The word “flowerbed flower†originated in the northeastern United States. Most local residents have large courtyards. They can construct seedbeds and grow herbaceous flowers. Therefore, such flowers planted on seedbeds are called bedding plants in our country. Many have been translated as flower beds. In the southern part of the United States, the climate is warm. Many seedbed plants in the northeastern United States require a two-year growth period, and they can often complete a life cycle within one year. They are called annual plants. In Europe, these plants are also the same, because local residents often do not have spacious courtyards. They are simply placed on a window sill and are called “window plantsâ€. Planted in gardens are called “garden plantsâ€. ". In the British Isles, these plants have a new name called "herbaceous plant." It can be seen that the above three words actually refer to a category of plants, which is what we are used to talking about. It should be pointed out that traditionally weeds do not include perennial plants, but in recent years, perennial plants have gradually been included in this area. In addition, the concept of flower is different in different regions. For example, in southern Europe, cyclamen can be used as a flower planted in a flower bed; in Japan, cyclamen is expensive and can only be used as a pot flower. In any case, if you call this type of flower in Chinese, the most appropriate way to express it is probably to be a “grass flowerâ€. Grass flowers usually include three categories: annual, biennial, and perennial. Due to the progress of breeding technology and the climate differences in different regions, the distinction between annual and biennial flowers is not obvious. In practical cultivation, annual flowers and two-year-old flowers are often collectively referred to as annual flowers, or two-year-old flowers are cultivated for one year, and even a few perennial flowers are used as annual flowers.
