Herbaceous plants in the forests of our country are far more common than shrubs and trees together.The length of the stem, usually small, although there are quite high - banana, cane, corn, etc.

feature that characterizes the herbaceous plants - is soft or juicy aboveground stem.There is a perception that these types of herbs are the result of the evolution of woody flora.Scientists came to this conclusion by comparing them with the anatomical structure of the anatomical structure of the related year-old branches of woody species.

Herbaceous plants on the term of existence are divided into several types: annual, biennial and perennial.

to the annual are those whose whole lifetime - one during the growing season, ie,one season, which is favorable for their growth.As a rule, the seeds of these plants germinate in the spring, and then they reach their normal size, bloom, bear fruit, and then they die completely.This millet, cucumber, tomato, corn, flowering aster, petunia, wild quinoa, cornflower, chickweed, etc.

biennial herbaceous plants have two periods of vegetation: the first images of their vegetative organs, then the leaves die off, and the roots remain, and in the second year of the kidney grow shoots, the plant bears fruit and then dies.It is known to us beets, cabbage, carrots, that alone can not tolerate the cold, so they usually gardeners dig up and store in basements or cellars, to spring to plant the seeds of pre-selected.Wild biennials - a burdock, thistle, caraway, chicory.

However, the vast majority of known species - is a perennial herbaceous plants, many of which do not reach the flowering period or in the first or even the second year of his life, but after five to ten years after seed germination.The period of flowering and fruiting they repeated up to twenty years.Annually kidney surface formed new shoots, which die off the end of vegetation, but not entirely: only the upper part of the die, with what is at ground level or below remains.Sometimes shoots spread out on the ground, pressed her bombarded plant residues.

Almost all herbaceous plants are perennial forests, many of which have long kept its place at the same time, thanks to its long roots and shoots ground, they spread in all directions, capturing new habitats.

This species do not breed seeds, as in the forest soil is almost always covered by a thick layer of fallen needles or leaves, which makes it difficult germination, propagation and vegetative means such litter is not a hindrance.

The forest grows many kinds zimnezelenyh herbs that safely hidden under a thick layer of snow.They are shade-tolerant and well tolerated in the absence of light.

However, the forest is not the only habitat of perennial herbaceous plants.Many of them are great and grow in meadows, glades, generally in any public place.Here they tend to grow much more elaborate, and flower and fruit are much more abundant.

Herbaceous plants of the forest is always very sensitive to soil conditions: the availability of nutrients and moisture, so they can be called a kind of indicator of the forest land.That is why many of them are closely related to their dissemination to the type of forest: some grow among deciduous, others - including conifers.

However, it is worth noting the fact that among the herbaceous plants there are also those who have a very wide area of ​​distribution that does not depend on the type of soil.This so-called indifferent plants.
