Topic 1: “Ornamental plant growing: characteristics of industries. Variety of ornamental plants."


Purpose of ornamental plants

The main purpose of ornamental plants is decoration. Such crops are divided into several types:

  • Garden.
  • Homemade.
  • Aquarium.

Aquarium plants are a separate part here. They, in addition to performing their decorative functions, play an important role in the life of underwater inhabitants. Aquarium vegetation is divided into several types:

  • Growing in the ground - limnophila, Indian fern, hemianthus dwarf, etc.
  • Living in water are Aegagropyla, Moss monosolenium and Java moss.
  • Living on the surface - Pistia, Riccia floating, Limnobium shooty, etc.


Duckweed is a small plant that lives on the surface of the water. It has small leaves with a convexity. The bulge is filled with air, which is why duckweed floats. Duckweed is used both as an ornamental plant and as an additive to the diet of fish. In addition, some fish use duckweed as cover for spawning. Duckweed is an unpretentious plant that takes root in almost any conditions. The main condition for its maintenance is a large amount of sunlight.

Java moss is a plant that lives in the water column. Its homeland is Southeast Asia. Moss looks like an interweaving of thin green threads. If left undisturbed, it can attach itself to objects and form attractive thickets. Fish use moss as a spawning site. The optimal temperature for moss is 23−28 degrees Celsius. At low temperatures it stops developing.

The Indian fern is one of the most popular aquarium inhabitants. In addition to decorative functions, it plays an important role in water purification.

When planting a fern, you should pay attention to the soil, it should be soft, sand is perfect. The optimal temperature ranges from 23 to 25 degrees. The aquarium should be in a well-lit place.

Trees for the garden

The fundamental part of the garden are trees and shrubs. Trees can be divided into deciduous and coniferous, and shrubs into climbing and flowering.

Coniferous trees decorate the garden throughout the year and are a salvation for the garden in the cold season. The main representatives of coniferous ornamental plants:

  • Fir is an evergreen tree that belongs to the Pine family. A distinctive feature of fir is its cones that grow vertically, which other pine representatives do not have. The plant has about 50 varieties, which can reach a height of 30 cm to 80 m.
  • Thuja is an evergreen, compact tree that exudes a pleasant spicy aroma. Thuja, like fir, has a large number of varieties. The average height of a tree ranges from 11 to 18 m, but there are also representatives up to 75 m high. All varieties of thuja are resistant to rotting and easily tolerate both winter cold and summer heat.
  • Kupressociparis is a prominent representative of coniferous trees. The tree is fast growing, with a cone-shaped crown. By ten years of cultivation, the plant grows up to 8-10 m, and up to 2 m wide. The branches of the tree grow upward and have small scaly leaves.

Among deciduous trees, the most striking are:

  • Canadian maple is a long-liver, living for 300-400 years. The leaf of this plant adorns the flag of Canada. The tree grows up to 40 m in height. Its crown is thick and wide, its diameter can reach 12 m. The tree reveals its beauty in the fall, coloring the leaves orange and bright red. The tree is frost-resistant, but suffers from gusty winds and hail. In the first years after planting, trees should be wrapped for the winter.
  • Japanese crimson is a rather exotic tree that grows mainly in Japan and China. The tree can easily grow in central Russia, but in winter it needs to be looked after. The height of the crimson plant is 5−7 m, the crown has an ovoid shape. The leaves are especially beautiful in spring when they turn purple-pink. It is best to plant a tree in a lighted place, but not in direct sunlight - it can burn the plant.
  • Chestnut is a tall tree belonging to the Beech family. It grows up to 35 meters in height. Its huge crown provides dense shade, and its beautiful flowers delight the eye every spring. In autumn, fruit pods grow on the tree. When they ripen, nuts will appear from there. Nuts are widely used in industry. Chestnut tolerates winter calmly, and can withstand heat in summer, but still, the optimal temperature for it is considered to be 20-27 degrees.

Which shrubs can be planted near the house and which cannot?

In addition to trees, you can plant the following beautiful shrubs near your house:

Lilac

Blooming

Flowering shrubs look very beautiful. To make flowers pleasing to the eye throughout the season, plant shrubs with different flowering periods.

Shrubs can be planted in groups of 3–5 specimens, and compositions can be made that include trees, shrubs and flowers. Bare trunks of shrubs decorate the site in winter, adding additional elements to the structure of the garden.

High

Shrubs can reach a height of three meters. For such tall plants, more space needs to be allocated accordingly. Tall shrubs such as lilac or jasmine look like trees. During the flowering period, such giants, strewn with bright flowers, look very beautiful.

Tall shrubs should be planted at a considerable distance from the wall of the house - 2.5-3 meters, so that the roots of the plant do not contribute to swelling of the foundation. It is also necessary to ensure that tall bushes do not obscure the windows of the house.

In Siberia

Residents of the northern regions can easily grow not only winter-hardy, but also heat-loving shrubs near their homes. However, you will have to cover them for the winter. If such troubles are not desirable for you, then limit planting near the house to only winter-hardy specimens.

What ornamental plants grow near a house in Siberia?

Winter-hardy shrubs include:

  • lilac;
  • spirea;
  • hydrangea;
  • buddleya.

Jasmine can be replaced with mock orange. It tolerates frost much better, and looks exactly the same as jasmine.

Behind the fence

More unpretentious species, such as lilac, barberry or mock orange, are usually planted behind the fence. These “simple” shrubs will serve as the beginning of the inspection, while real beauty will greet guests on the site itself in the form of park roses, spirea and hydrangea.

Shrub crops

Ornamental shrubs are a large group of perennial plants that have different shapes and proportions. Most ornamental shrubs are deciduous, but there are also coniferous specimens.

Types of trees

All trees that have decorative properties are divided into deciduous and coniferous. Conifers are evergreen and also have a permanent shape and are a good salvation for the garden during the off-season. The most famous representatives of coniferous plants are thuja, fir or cupressociparis.
