Characteristics of herbaceous plants differences between herbaceous plants

Herbs are one of many plants, I believe everyone may not know, let's get to know it together! Look at the characteristics of herbs.

What are herbs?

Most of the branches of herbs die after the growing season, but the roots of underground parts can grow again in two years. The roots of perennial herbs are generally stronger, and some of them also grow roots, tubers, bulbs, bulbs and other organs. In winter, the parts on the ground still sleep quietly. When the climate turns warm the next year, they sprout and grow again. This year after year growth, underground roots or stems may gradually become fat, may also branch.

Classification of Herbs

Annual herbs refer to herbs that germinate, grow, bear fruit and wither and die from seeds. Their life span is only one year, that is, they can complete their life cycle within one growing season. biennial herb that grows only vegetative organs in the first growing season and dies after flowering and fruiting in the second growing season, e.g. winter wheat, sugar beet, broad bean, etc. Perennial herbs, life is longer, generally more than two years of herbs, such as chrysanthemum, water lily, clivia, etc.

Herbs have less developed to underdeveloped xylem and succulent, softer stems. According to the length of the life cycle of herbs, they can be divided into annual, biennial or perennial plants. Most herbs die at the end of the growing season, including annual and biennial herbs such as rice, radish, etc.

The aboveground parts of perennial herbs die annually, while the roots, rhizomes, and bulbs of underground parts, such as geraniums, can live for many years. Herbs, annual, biennial and perennial habits, sometimes with geographical latitude and cultivation habits change and change, such as wheat and barley in autumn sowing for biennial herbs, in spring sowing when they become annual herbs; and such as cotton and castor in Jiangsu and Zhejiang provinces for annual herbs, but in the low latitude south can grow perennial herbs.

Life is longer, generally more than two years of herbs, such as chrysanthemum, orchid, lotus, water lily, clivia, etc. Perennial herbs roots are generally stronger, some also grow roots, tubers, bulbs, bulbs and other organs, winter, the ground part is still quiet sleep, to the next year warm climate, they germinate and grow. This year after year growth, underground roots or stems may gradually become fat, may also branch.

This gives us a basis for identifying their age; its age can be inferred from the number of branches in its underground parts, the size, length and thickness of its stems or roots. Perennial herbs can live for more than two years.

The underground part of some plants is perennial, such as perennial roots or rhizomes, bulbs, root tuber and other abnormal organs, while the above-ground part dies every year, and new branches grow from the underground part in the spring of the next year, flowering and fruiting, such as lotus root, onion, taro, sweet potato, dahlia, etc.; In addition, the above-ground and underground parts of some plants are perennial, after flowering and fruiting, the above-ground part is still not dead, and can bear fruit many times, such as Evergreen, Op, etc.

Characteristics of Herbs

1. Annual flowers: Herbs that are generally sown in spring and bloom in summer and autumn. The seeds mature in autumn and the plants die in winter. They complete a life cycle in one year. Such as a string of red, cockscomb, zinnia, impatiens and so on.

2, biennial flowers: generally sown in autumn, the following spring and summer flowering herbs. Summer seeds die when they mature. They grow annually, but less than two years. Such as calendula, melon, pansy, snapdragon and so on.

3. Perennial root flowers: individual life span exceeds two years, and they are perennial herbaceous flowers. Cold-resistant, winter can be winter in the open field, can blossom and bear fruit many times, underground part of the normal shape, such as chrysanthemum, gerbera.

4, bulbous flowers: individual life span of more than two years, perennial herbaceous flowers. Its underground part has enlarged deformed stems or roots, and there are five types. (1) Bulbs: with a large number of fat scales. Such as narcissus, lily. (2) corms: spherical in shape and solid inside. Gladiolus, for example. (3) Tubers: underground stems into blocks, such as calla lily. (4) Rhizomes: underground stem hypertrophy and formation of thick and long rhizomes, which have obvious nodes and internodes. Such as canna. (5) Root tuber: formed by expanding roots, such as dahlia.

5. Aquatic flowers: This class belongs to perennial herbaceous plants. The underground part is mostly hypertrophy and rhizomatous, growing in shallow water or swamp areas. Such as lotus, water lily.

6. Ferns: This class belongs to perennial herbs, mostly evergreen, which do not flower or produce seeds. Such as kidney fern, antler fern.
