Botanical description of irises: an excursion into history
Iris is an ornamental, perennial plant belonging to the Iris family. It is believed that the first flowers came to us from Asia. Under natural growing conditions, irises can be found in North America and Europe.
Beautiful iris flowers enchant with their airiness and tenderness
These are the most beautiful and common flowers. They decorate city parks and flower beds in summer cottages.
The plant has a long erect stem, elongated basal leaves, and huge flowers of different colors. In addition to decorative properties, irises also have medicinal properties. They are used to treat many diseases.
Irises - flowers of the goddess Iris
The iris got its name in honor of the ancient Greek goddess of the rainbow - Iris. And the name was given to it by Hippocrates. If you believe one legend, then at the time when Prometheus was distributing fire, a rainbow spread across the sky. One could admire such a beautiful event all day long, and the next morning, when the rainbow disappeared, flowers appeared that completely repeated the rainbow: they shone with all its colors.
In ancient times, iris was considered a powerful aphrodisiac. Men and women who consumed the powder believed that it caused a strong desire. The aroma of the flower was so strong and pleasant that it had an exciting effect on people and set them up for a loving pastime.
Variety of species
Planting and care
Botanists have divided the diversity of the natural world of irises into 2 types: rhizomatous and bulbous. Rhizomes, in turn, are divided into bearded and non-bearded or beardless. Each species has its own characteristics and growing conditions. Let's look at each type in more detail.
Bearded irises are the kings of the garden
The large group of charming irises includes tall, standard, low and dwarf plants.
Distinctive features of bearded irises:
- Coloring. You can find flowers ranging from snow-white to dark charcoal. Breeders have not developed only one variety of irises - there is no pure scarlet color.
- Texture. The petals have both a translucent and dense structure. You can find petals with a waxy texture
- Form . Thanks to breeding work, you can buy flowers of a classic shape, and if you want something original and unique, then you have the opportunity to have varieties with beautiful, foamy lace of openwork petals in your garden. Such flowers look like a soaring bird.
- Size. Among a wide range of low-growing and tall varieties, you can choose one that will be appropriate in landscape design and that will be attractive in appearance.
Beautiful varieties of bearded irises - worthy garden decoration
A wave of new varieties of bearded irises simply swept the country in the early 90s. Mass distribution played a cruel joke, turning against the flowers themselves. It was generally accepted that the newest varieties were inferior in quality to the older ones. However, this is an exaggerated opinion, so you should not give up beautiful varieties of irises for the sake of someone else’s opinion.
Among the huge variety you can find not only bearded irises, there are also Dutch and reticulated irises, which bloom in early spring from a planted bulb.
Dutch irises (xyphiums)

They prefer sunny areas with fertile soil and neutral acidity. They look beautiful when cut and can be grown in flower beds and flower beds.
Reticulated irises (iridodictiums)
This group belongs to dwarf plants, not exceeding 10-15 cm in height. Such low-growing varieties are used to decorate borders, in flowerbeds, and look beautiful in flower beds.
Reticulate irises
However, low foliage is only before flowering. When the specimens fade, the foliage reaches a height of up to 50 cm. They bloom very early. Due to such early flowering, people also call them snowdrops.

Features of planting Dutch, reticulated and bearded irises
Many gardeners do not want to plant irises on their property, citing the fact that caring for flowers requires having some specific knowledge.
But growing irises is not a labor-intensive task; you just need to know the varieties of iris you purchased and how to care for the particular variety you bought in the store.
Unpretentious plants serve as a worthy decoration for a suburban area
Features of growing bearded irises
1The first feature is that some rhizomes grow horizontally and may become bare over time. Therefore, it is recommended to cover the plantings with mulch for the winter to prevent the roots from freezing .
2 Irises do not tolerate excess organic fertilizers . If you want to pamper your plants, it is better to apply mineral fertilizers dissolved in water for planting.
3 When planting, it is advisable to pour sand into the bottom of the hole . If you bury the rhizome, the flowers will stop blooming.
4During the growing season, irises have the ability to move to a certain distance other than the planting site. To make the rows look even, you will need to plant irises in a fan along the row, not across.
By following simple rules, you can create a beautiful and compact flower garden that will decorate your summer cottage.
Contrary to the generally accepted belief that irises need to be divided immediately after flowering, it can be said that irises can be replanted at any time of the year: early spring, summer and even autumn. If the weather in the region is warm, then there is no need to rush to transfer.
It is recommended to replant bearded irises once every 3 years in order not only to propagate the variety, but also to prevent it from dying. Siberian irises are replanted less frequently, once every 10 years. It can be done more often, the main thing is to prevent the variety from degenerating.
Planting bearded irises
Bearded irises prefer areas with good light. They do not like drafts, so for planting it is recommended to choose a sunny place, protected from the winds. In the spring, when the snow melts, moisture should not linger in the area with irises.
Before planting, you need to dig a hole that will correspond to the size of the iris root system. It is recommended to pour fine river sand into the bottom of the hole. Then, you need to place the rhizome on the resulting mound of sand, straighten the roots and sprinkle them with soil.
A mixture of bright colors of bearded irises stands out as a bright spot on the site
When planting, you need to make sure that the upper part of the rhizome is not deeply buried in the soil . It is better to do so so that part of the rhizome protrudes slightly above the surface and is accessible to the rays of the sun.
Planted plants do not need watering. If the division of the iris and its subsequent planting were carried out in the previous year, it is recommended to remove the flower shoot so as not to deplete the plant’s strength.
If you really want to admire the flowers of a new variety, it is recommended to cut off the peduncle with buds. They will bloom already in the vase, and using this method, you will not deplete the plant.
Features of planting Dutch irises
In stores you can find bulbs and rhizomes of Dutch irises. Rhizomatous irises are planted in August or early September. The site should have loose, breathable soil, soil with low acidity.
Before planting, it should be taken into account that irises should not subsequently be obscured by other tall plants, otherwise such proximity will negatively affect flowering.
Delicate Dutch irises grown from bulbs
For planting, dig a hole that is 2 times larger than the size of the rhizome itself. After the rhizome is covered with soil, you need to add another layer of mulch. This will prevent the soil from freezing in winter, and in summer it will protect the root system from overheating. You can mulch with hay, straw, and tree bark.
Planting bulbs
Iris bulbs
There are some discrepancies in planting rhizomes and bulbs, which are important to take into account when planting the prepared material:
1Before planting, iris bulbs must be placed in a fungicide solution for disinfection. This procedure will prevent the possibility of rotting of the bulb. After removal from the solution, the planting material must be dried.
2The planting site must be spilled with a weak solution of potassium permanganate to kill pathogenic microorganisms.
3The bulbs should be planted according to a 15x15 cm pattern. With this planting, the specimens will not shade each other.
4At the end, the bulbs are sprinkled with soil and watered.
Dutch irises bloom in mid to late May, but there is a discrepancy: some bloom in early June. The buds quickly wither, especially on hot days.
Caring for Dutch flowers after flowering
After flowering, it is recommended to wait for the foliage to dry, then dig up the bulbs and dry for 2 weeks in a well-ventilated area.

Some gardeners recommend drying outdoors , but you need to make sure that the scorching rays do not dry out the bulbs. Store in canvas bags in a ventilated place.
Selecting a location
When choosing a site for growing irises, you should give preference to open places with plenty of sun, but without drafts. Stagnation of moisture should also be avoided. Good drainage is essential for these plants.
The soil in which the plant will be planted is pre-enriched with compost or mineral compounds. Acidic soil is diluted with dolomite flour or wood ash. Peat is added to the loam. Clay soil is mixed into sandy soil.
Before planting, the soil is disinfected and impregnated with fungicides or herbicides to prevent weed growth.
General rules for caring for plants
Caring for irises does not involve difficulties; it is important to know what the plant likes and follow its whims
Soil selection and preparation
- Irises prefer fertile soil with neutral acidity. Can be planted on loams.
- Flowers can be grown in the same place for no more than 3-5 years, then it is recommended to transfer the planting to a new permanent residence.
Watering
- When planting, the rhizomes are located close to the soil surface, so excessive soil moisture can cause root rot.
- Over-watering contributes to the appearance of black, unsightly dots on the foliage, which subsequently also rot. Therefore, in the first half of summer, the plant is watered abundantly, and starting from the second half, watering is reduced.
- Elegant and beautiful irises can be grown by March 8th.
- Women will be delighted with such a gift. For forcing you need to take bulbous irises.
Illumination
- Good growth of irises and abundant flowering largely depends on the choice of location. The area should be well lit.
- When shaded, the irises will not have enough light, so the brightness of the flowers will be lost and flowering will be more sparse.
- Flowers are badly affected by gusts of wind and drafts. Therefore, when choosing a site, you need to take this feature into account.
Temperature
- Almost all types of irises tolerate even the most severe frosts well, so when preparing for winter you will only have to lightly mulch the ground.
- Beautifully decorated flower beds with irises attract the attention of passers-by. I just want to stop and inhale the aroma of charming “butterflies”.
Fertilizer application
- Irises need additional nutrients, especially when grown in one place for a long time. The first feeding is carried out in early spring. At this time, mineral fertilizers are scattered between plantings.
- During budding, it is recommended to apply potassium fertilizers. In August they are fed with phosphorus and potassium supplements. This procedure improves immunity and helps plants survive the winter.
Transfer to a new place
- When grown in the same place for a long time, you can notice such a feature that the irises stop blooming. This means they need to be transplanted into new nutrient soil.
- Plants are replanted after they have flowered. During this time, the irises have time to take root in a new place. Transplanted irises begin to bloom in the 2nd year.
- Before planting, mineral fertilizers are applied to the soil. Gardeners do not recommend adding organic compounds to the soil.
Propagation of irises
There are several ways to propagate irises: seed and vegetative.
Seed propagation is used mainly by breeders to obtain a new variety. This method is used quite rarely by summer residents, as it has certain difficulties.
Preparing the bush before dividing the rhizome
When forcing irises, it is important to use additional lighting. If it becomes clear that you are not meeting the deadlines, then you can extend the time for additional illumination of the plants. And then you can definitely get the treasured bouquet of irises for a certain holiday.
Vegetative propagation is carried out by dividing the rhizome into parts. With this method, flowering occurs the next year.
By dividing the rhizomes, wild and varietal irises can be propagated.
Rules for dividing rhizomes
1For propagation, you need to choose a healthy mother plant, without visible damage by pests and diseases.
2After removal from the ground, it is necessary to shake off the sand from the roots and divide the rhizomes into parts so that each of them contains one leaf bud or bunch. The delenka must have its own root system.
3For better rooting, the foliage will have to be cut by half, and the roots by 1/3.
4When dividing, inspect the rhizomes and remove damaged leaves and roots.
5Next, you need to disinfect the cuttings by immersing them in a weak solution of potassium permanganate for 15 minutes.
6The cut area should be sprinkled with coal.
Before planting, river sand is poured into the hole, part of the rhizome is placed on it and sprinkled with soil. When planting, it is important to maintain a distance of 0.5 meters between specimens.
What to do when irises have bloomed
If replanting is not planned this year, the flower stalks are cut off. If yellowness appears on the leaves, it also needs to be removed. The cut is made semicircular to make it look aesthetically pleasing. The iris will continue to decorate the flower garden and gain nutrients.
When the leaves wither in the fall, they are cut off at a height of 10 cm. The cut part must be burned to destroy the spores and eggs of pests and diseases.
Before winter, irises are mulched with pine needles, sawdust and peat. It is also recommended to cover them with spruce branches. For weakly resistant varieties, you can make a small greenhouse or greenhouse.
Pests and diseases of irises
Irises are unpretentious plants that feel great even with minimal care.
However, sometimes plants can get sick or be attacked by pests. To prevent the colonial spread of insects, you will need to inspect the plantings more often for diseases or harmful insects.
Leaf base rot and root rot When growing irises in waterlogged soil, a scourge such as rot occurs. To fix the problem, the plant will need to be removed from the ground, cleared of soil and all diseased areas removed, cutting with a knife to healthy tissue.
Next, you will need to dip the remaining rhizome in a growth stimulator solution. After the plant has dried a little in the sun during the day, it can be planted on the site.
Gladiolus thrips Signs that gladiolus thrips has settled on the plant can be recognized by the foliage - it becomes lethargic and loses its glossy shine. The fight needs to be carried out only with the help of special chemicals; folk remedies do not give a positive result.
Heterosporosis When examining the foliage of a diseased plant, you may notice small brown spots. As a preventive measure, it is necessary to cut off the entire above-ground part and burn it away from the site. After this, the irises need to be treated with a solution of copper sulfate.
Industrial and medical applications
Some varieties of irises are used for industrial purposes. The root is ground into powder and added to laundry and cosmetic products and toothpastes. It is present in shampoos, shower gels and gives a pleasant aroma to cosmetics.
