Flower garden and landscape

Beauty and treachery - poisonous plants in garden design


Country and house sections are inconceivable without flowers. Modest paths framed by tulips, lush flower beds of annuals that amaze the eye with a color combination, green-blue conifers. Beautiful flowers in the garden, in the house, in city parks and squares. But, as the great actress Ranevskaya said in one of the films: "Beauty is a terrible force," plants and flowers are dangerous. I’d like to prolong the meeting with them, and now there’s a bouquet on the table, a nose in pollen, a stalk in my teeth, and then, and further ... malaise, ambulance, resuscitation. It is necessary to work with some plants and flowers, sometimes with gloves, and enjoy the aroma at a decent distance.

Starting to decorate the garden, landscaping the landscape of the house area, you need to familiarize yourself with the data on the selected crops. From 350 thousand flowering plants, remove poisonous plants from the garden and home (or reasonably protect from children, especially allergy sufferers). Make flowerbeds and flower beds in your garden safe.

Some of the plants grown may be, to one degree or another, hazardous to health.

Poisonous perennial shrubs

Not a single private plot of land, a public park or square can do without landscaping in the form of flowering broad-leaved shrubs, bushy creeping conifers, perennial herbaceous plants. Not all of them are harmless to humans and animals. Habitual plants may have properties that are harmful to health.

After reading the article and other materials, some will want to take drastic measures. But plants do not have to be destroyed. They can be shielded or transplanted to another place so that it is inaccessible to children and animals, lovers to try everything on a tooth or tongue.


Often, white, bluish, light or dark pink elegant balls of Hydrangea hang from the front gardens. Not all hydrangeas are poisonous. However, if animals bypass the bush, they will not eat a leaf - a sure sign that the plant is poisonous.

A large amount of cyanide is contained in Large leaf hydrangeas (Hydrangea macrophylla), especially in flower buds. The color of inflorescences does not affect its toxicity. Obvious symptoms of poisoning occur if you chew on leaves or a flower bud: shortness of breath, fainting, pressure drop with a rapid pulse, convulsions.

Hydrangeas are moderately toxic plants, all parts of the plant contain cyanogenic glycosides, the use of all parts of the plant in food is contraindicated and can lead to poisoning.

For cultivation in the garden, you can use Russian cultivars, which in general manifestations of toxicity disappear with age. Hydrangea serratus, or Tea hydrangea (Nydrangea serrata) - a welcome shrub in the garden. Its leaves are not poisonous. In Japan and Korea, because of their high sugar content, they are even used as a sweetener in gratuities for diabetics.

Charming Oleander ordinary (Nerium oleander) strewn with delicate pink flowers leaves no one indifferent. The plant is so magnificent in its lush beauty that some gardeners, even knowing its toxicity, still grow this plant not only in open ground, but also in apartments, conservatories and greenhouses.

The graceful appearance hides big problems, especially terrible for young children. The whole plant is poisonous: flower nectar, juice, young shoots and leaves. One leaf can damage the central nervous system, affect the digestive and circulatory systems. A pleasant enticing aroma causes headache, nausea, shortness of breath until necessary and take resuscitation measures.

The danger of oleander is due to the content of oleander, cornerin and other cardiac glycosides in the plant.

Another poisonous plant is the evergreen shrub Rhododendron (Rhododendron), whose leaves also serve as a living decoration of the garden in winter. For the extraordinary beauty of the spectacular large flowers of the bush, pink, white, purple and other colors, rhododendron is called a divine plant. But all parts of the plant are poisonous in rhododendron and can cause coma if ingested.

Rhododendrons contains andromedotoxin, which refers to neurotoxins; it disrupts cellular receptors, which can be fatal. Azaleas, from the same family, can also be attributed to poisonous plants.

Poison green fence

Sometimes areas with shabby fences are ennobled with decorative shrubs using Daphne (Daphne), Snowberry (Symphoricarpos), Biryuchin (Ligustrum), Euonymus (Euonymus) other. Beautiful thickets are highly decorative all year round. Bright boxes of euonymus with fleshy berries hiding poisonous seeds, white juicy berries of a snow-berry, black privet berries are so deceptively appetizing that children often taste them without the knowledge of their parents.

However, the fruits of these poisonous plants contain poisonous alkaloids that can cause dizziness, vomiting, and fainting.

Not needed in the country and daphne. All parts are poisonous in it - bark, leaves, flowers and even berries. Wet bark causes irritation of the skin and mucous membranes of the eye, and several berries eaten can cause death in children.

Poisonous conifers

The needles are unusually decorative. Decorators consider conifers to be the queens of landscape design. Sometimes in large house sections, trimmed lawns intended for rest are decorated with coniferous crops - Juniper (Juniperus), Yew berry (Taxus baccata), Thuay (Thuja) Among these cultures, there are harmless representatives and rather poisonous species.

For example, yew berry is one of the most poisonous plants in the southern regions. In plants, the high content of poison in wood, bark, needles, young shoots. But the most poisonous in yew are seeds hidden in a fleshy bright scarlet berry.

Juniper Cossack, the leader among the poisonous species of junipers, has black berries with a gray bloom, a high content of highly toxic esters and resins, and young annual growths are poisonous.

Creeping forms of conifers are considered especially dangerous, some species of thuja are considered partially poisonous. Refuse to decorate the garden with conifers is not necessary, but it is necessary to protect them from the penetration of children. If this is tapeworm planting, remove them away from the rest areas, if a mixborder is framed, it is better to separate it from the tracks with a tape of green plantings of non-poisonous flowers.

Poisonous flowers

Increasingly, residents of forests and fields appear on the plots. The beautiful lily of the valley bowed its bell, beckoned the raven eye with a berry, reached out to pick sleep-grass, to taste the small attractive bulbs of early spring flowering. But flowering is not so harmless. Their beauty also has "terrible power."

They are familiar to you.

The bulbs of these plants are extremely toxic to humans. They cause nausea, vomiting, severe diarrhea, allergic sufferers - a choking cough. You need to work with these plants with gloves, do not touch your eyes, do not drink milk, as it accelerates the absorption of poison by the body.

Zantedesia (callas)

In some local areas, gardens, city parks and squares, large flower beds and rockeries grow perennial callas - Zantedesci (Zantedeschia) They are bewitchingly beautiful in their austere beauty. There is only one folded leaf (calla), but how much grace there is and one cannot but add - poison.

The intracellular juice of the plant is poisonous. All parts of the plant contain calcium oxalate, which forms needle crystals in the internal organs.

The Dangers of Moorish Lawns

In a brief article of an educational nature, there is no way to acquaint the reader with all the poisonous beautifully flowering and decorative-leafed and garden plants. But even the information listed above gives an idea of ​​what plants we are friends with, not suspecting their true "character."

Moorish lawn

Today more and more often dachas and adjoining plots are used for recreation, rather than daily labor in vegetable beds and in the garden. The design of the rest areas in the style of the Moorish lawns, which actually represent a certain area sown with various field plants, is in fashion.

For such a lawn, 10-40 species of beautifully flowering field plants are selected, mixed and sown. The lawn is not mowed until the seeds have fully ripened, which by self-sowing next year will multiply and restore the green outfit of a wonderful corner of rest.

Analysis of the proposed ready-made mixtures for sowing showed that the seeds of poisonous plants prevail in them, so it is better to make a mixture of seed material yourself. Calendula, flax, cornflowers, chamomile, cloves, forget-me-nots, various types of ornamental cereals can be safe.

In various sets of early-flowering plants, bulbous sprouts, tulips, daffodils, crocuses, cyclamens are recommended. But these representatives of the flora also belong to poisonous plants. They, if used to decorate the lawn, then only that part where there will be no playgrounds.
