What's the difference between flowers and grass? Let me help you tell them apart easily

There is no essential distinction between flowers and grass; flowers were selected out from grass, and flowers come from grass. It is only that the two differ in where their visual impact lies. Grass generally refers to relatively low-growing foliage plants; flowers are the reproductive form of flowering plants and generally refer to herbaceous plants with ornamental value.

1. What are herbaceous plants?

They refer to plants whose stems have poorly developed xylem, contain few lignified cells, and have weak supporting strength. Herbaceous plants are generally very short in stature and short-lived, with soft stems, and most die back above ground or as a whole plant at the end of the growing season. According to the number of years needed to complete the entire life cycle, they are divided into annual, biennial and perennial herbaceous plants.

2. What are herbaceous plants with ornamental value?

Flowers, herbaceous plants with ornamental value, are a general term for plants grown to be appreciated. They like sunlight and tolerate cold, have short branches with a reproductive function, and come in many kinds. A typical flower, on a short axis of limited growth, bears a calyx, petals, and stamens and pistils that produce reproductive cells. A flower is composed of the corolla, calyx, receptacle and stamens and pistils, comes in all kinds of colors, and some grow very showy and fragrant.

Some scholars believe that the strobilus of gymnosperms is also a “flower”, while most people believe that only angiosperms have true flowers, so angiosperms are also called flowering plants. The various parts of a flower are not easily affected by the external environment, and for a long time people have used the morphological structure of flowers as the main basis for the classification, identification and systematic evolution of angiosperms.

3. What are woody plants?

Woody plants are sturdy plants whose roots and stems form large amounts of xylem through thickening growth, and whose cell walls are also mostly lignified. Woody plants can be divided into three types according to plant height and branching position:

1. Subshrubs: plants are perennial, with only the base of the stem lignified while the upper part is herbaceous, withering in winter, such as the tree peony;

2. Shrubs: relatively short trees, under 5 m tall, with branches close to the base of the stem, such as tea, Chinese rose and rose of Sharon, with evergreen shrubs and deciduous shrubs distinguished;

3. Trees: tall and upright, reaching over 5.5 m in height. The trunk is obvious and the branching position is relatively high, such as pine, China fir, Chinese wingnut and camphor.
