They use formulas and diagrams that give a visual representation of its structure.

Flower formula- This symbol structure of a flower using letters, numbers and signs.

When drawing up the formula, use the following notation:

Ca- calyx ( Calyx);

Co- corolla ( Corolla);

R- simple perianth ( Perigonium);

A- androecium, a collection of stamens ( Androeceum);

G- gynoecium, a collection of pistils ( Gynoeceum);

* - actinomorphic flower;

Zygomorphic flower;

? - bisexual flower (usually it is omitted in the formula);

? - female (pistillate) flower;

? - male (staminate) flower;

() - brackets mean the fusion of flower parts;

Plus indicates the arrangement of flower parts in two or more circles (for example, R 3+3 - simple perianth, of 6 leaflets arranged in two circles) or the fact that the parts separated by this sign differ from each other ( A 1+(9) - androecium consists of one free and nine fused stamens);

Ca 5- the number next to the symbol indicates the number of members of this part of the flower ( Ca 5 - calyx of 5 free sepals);

∞ - if the number of members of a given part of the flower is more than 12, then their number is indicated by an infinity sign (for example, A ∞- the number of stamens is more than 12).

The formulas also note ovary type by location on the receptacle (upper, lower, middle):

G 1- a line above the number means that the ovary is inferior;

G 1- line under the number - superior ovary;

G 1--- a line from the number - the ovary is semi-inferior.

Examples of flower formulas are given below.

* ? Ca 4 Co 4 A 2+4 G(2) - formula of the cabbage flower: actinomorphic, bisexual; double perianth, in which the calyx consists of 4 free sepals, the corolla - of 4 free petals; androecium has 4 long and 2 short stamens (quadruple androecium); The gynoecium is simple, coenocarpous, formed by 2 carpels (1 pistil - from 2 carpels), the ovary is superior.

? Ca (5) Co (2+3) A 2+2 G(2) - formula of the white claret flower: zygomorphic, bisexual; double perianth, in which the calyx consists of 5 fused sepals, and the corolla - of 5 fused petals (2 petals form the upper lip, and the other 3 petals form the lower lip); the androecium is formed by 4 free stamens, of which 2 are long and 2 are short (double androecium); The gynoecium is simple, coenocarpous, formed by 2 carpels (1 pistil - from 2 carpels), the ovary is superior.

* ? R 3+3 A 3+3 G(3) - lily flower formula: actinomorphic, bisexual; a simple perianth consists of 6 leaflets, which are arranged 3 in 2 circles (simple corolla-shaped perianth); androecium consists of 6 free stamens, arranged 3 in 2 circles; The gynoecium is simple, coenocarpous, formed by 3 carpels (1 pistil - from 3 carpels), the ovary is superior.

? Ca (5) Co 1+2+(2) A (9)+1 G 1 - pea flower formula: zygomorphic, bisexual; double perianth, in which the calyx consists of 5 fused sepals, the petals have different shape and size: one large petal - a sail, two free side ones - oars (wings) and two fused ones - a boat (moth-type corolla); the androecium consists of 10 stamens, of which 9 are fused into a tube and 1 is free - bifraternal androecium; The gynoecium is simple, monocarpous (1 pistil is formed by 1 carpel), the ovary is superior.

Flower diagram more clear than the formula. It represents a conventional schematic projection of the parts of a flower onto a plane and reflects their number, relative sizes and relative position, as well as the presence of accretion (Fig. 16, 17).

The diagram indicates the location of the covering (bract) leaf, bracts and the axis of the inflorescence or shoot bearing the flower. The bract, bracts and sepals are represented by brackets with a keel (curly brackets) various sizes, petals - in round brackets, stamens - in the form of a section through the anther or in the form of a shaded ellipse, gynoecium - also in the form of a section through the ovary with a drawing of the placentation site and ovules through which the section passed.

The diagram is designed so that the covering leaf is at the bottom, the axis of the inflorescence is at the top, and between them the parts of the flower are located in circles with conventional signs. When parts of a flower grow together in the diagram conventional signs connected to each other by a line.

Iris is a flower that personifies one of the most beautiful phenomena of nature, is affectionately called “kasatik” by the Russian people. This proud flower, directed towards the sun, shining, shimmering with all colors, attracts with its inexplicable intimacy, reverent tenderness and fragility.

This is a miracle of nature inspires all lovers of beauty. The beauty of irises attracts artists, composers dedicate operas and romances to it, and poets dedicate poems to it.

Features of the iris, morphological and biological

Iris belongs to the iris family (Iridaceae juss). On globe There are about 200 species of iris, widespread in Europe, Asia, Africa, North America. These are plants of different habitats: mountains and meadows, steppes and swamps, deserts and river banks. They have fan-shaped tufts of leaves and strong peduncles with 1-10 flowers.

Irises are perennial herbaceous rhizomatous plants. Those of them that have a bulb are now separated into separate genera. They have already become Junos, Xyphiums, Irido-dictiums, Gynandriris.

Structure of an iris flower

Simple iris flower, has internal and external perianth lobes, called “petals” by flower growers (Fig. 1).

Three outer lobes bent downwards or positioned horizontally and are called foreign literature falls (from the English falls - “waterfall”), the three inner ones are raised up, bent towards the center of the flower and are called standards (from the English standards - “banners, flags”).

This the arrangement of the perianth lobes makes the flower unusual and easily visible to insects. The perianth lobes consist of a marigold (narrow part) and a plate (widened part).

Records varied in size, shape and color. The perianth lobes grow together at the base and form a tube. The bottom of the flower is covered with involucre leaves. The outer petals play a major role in opening and closing the flower and serve as a “landing platform” for insects.

In hybrid bearded irises on the outer lobes there are multicellular hairs - a beard, which decorates the flower and serves to attract insects. Both the outer and inner lobes of the perianth perform signaling functions.

In some species iris (marsh iris, common iris), the internal lobes are reduced. The pistil consists of three petal-shaped lobes of the style, a three-lobed stigma and supra-stigial ridges. The latter protect the stigma blades from rain. The stamens have three filaments in the lower part fused with the perianth tube

According to the shape of the flower The iris rivals the orchids themselves. Elastic petals, corrugation, folds, and horizontal lower lobes of the perianth determine its luxurious shape. In the most modern varieties, the edges of the lobes are decorated with many small bubbly swellings, creating a lace effect.

Separation of iris by flower color

The very name “iris” speaks of the richness of colors., inherent in its flowers: from white, blue, purple to almost black, from cream and yellow to orange; from soft pink to red and brown. Often, one flower combines contrasting tones or merges into complex iridescences of different shades, which are difficult to name.

Based on the color of the flower, varieties are divided into:

One of the most stunning spring-blooming herbaceous perennials is the Properly Bearded Iris. Having a rich palette of colors and shades, divided into groups according to flowering time and height, it has become not just a decoration for gardens, but a source of pride for many collectors. Its selection has a rich history and includes tens of thousands of registered varieties and cultivars unknown to a wide range of people. But, despite the diversity, breeding work does not stop, perhaps because crossing iris sometimes gives amazing results and is not considered difficult.

Classification of bearded iris

Bearded iris has a rather complex hybrid origin. Its ancestors are different natural species: German iris, dwarf iris, Trojan iris, Cyprus iris, pale iris, etc. That is why it has so many forms and varieties. And it is for this reason that it still does not have a single classification recognized throughout the world.

The simplest classification of bearded iris is division by height. The low-growing group includes plants with a height of only 40 cm. The medium-growing group includes plants up to 70 cm. All varieties above 70 cm are considered tall.

Wherein dwarf irises They are divided into miniature, with a peduncle height of up to 20 cm and one to three flowers on it, and standard - with a peduncle height of 21 to 40 cm and two to four flowers.

Medium-sized bearded irises are divided into 4-flowered ones (IB - intermediate bearded), those that have more than 6 flowers on one peduncle (BB - boarder bearded), and the so-called miniature ones (MTB - miniature tall bearded).

The tall group is not divided into subgroups.

According to the classification adopted by the Russian Iris Society (ROI), Properly Bearded irises are divided into:

• Tall Bearded (TV – Tall Bearded);
• Standard Medium Bearded (SMB – Standard Median Bearder);
• Small-Flowered Median Bearder (SFMB - Small-Flowered Median Bearder);
• Binding Medium Bearded (IMB – Intermediate Median Bearder);
• Standard Dwarf Bearder (SDB – Standard Dwarf Bearder);
• Miniature Dwarf Bearder (MDB – Miniature dwarf Bearder);
• Non-Aril-like Arilbreds ((-) AB – Non-Aril – like Arilbreds);
• Arils and Aril-like Arilbreds (AR& (+)AB (Arils and Aril-like Arilbreds)

According to the flowering periods, bearded irises are:

• very early (V – very early),
• early (E - early),
• mid-early (ME – medium-early),
• medium-late (ML – medium-late),
• late (L – late),
• very late (VL – very late).

There are also varieties with repeated (two or more) flowerings - remontant (Re - Rebloomers), but in the conditions of most of our climatic zones, unfortunately, in the vast majority of cases, remontantness does not manifest themselves in them, so there is practically no data on them in Russian.

Irises are also divided according to flower size:

• with small flowers,
• with average
• with large
• with very large ones.

There is a classification based on the color of fouls and standards:

• single-color irises (self) - distinguished by the same coloring of all perianth lobes;
• two-tone (bitone) - have two shades of the same color, one of which is painted in the upper lobes, the other in the lower lobes;
• two-color (bicolor) - carry two different colors.

Among the latter, the following groups are distinguished:

• amena (amoena) – with white upper petals;
• variegate - with yellow upper and dark red lower ones;
• plicata (plicata) - with anthocyanin (from pink-lilac to dark purple) patterns on the light surface of the perianth lobes;
• luminata - with an uncolored part around the beard on the anthocyanin background of the lobes;
• plicata-luminata or fancy-plicata (plicata + luminata) – a combination of plicata and luminata indicators;
• glaciate – pastel shades with the absence of anthocyanin elements;
• iridescent (blend) - with smooth transitions from one color to another;
• reversible – standards darker than foul;
• with “broken” color (brokencolours) – with splashes of contrasting color on a plain background.

Breeding bearded iris

Thanks to people's love for this wonderful perennial, over a hundred new varieties are born every year. The most intense group, and also the most popular, are the Tall Bearded Irises. The variety of shapes of their flowers and the combination of colors is simply amazing. But, despite this, breeders continue to work, surprising the world with new wonderful achievements.

How to develop a new variety?

Withdraw new variety Even a novice amateur gardener can grow bearded iris. This requires a little patience, some knowledge and determination.

The first place to start your selection work is to study the structure of the flower.

Structure of the bearded iris flower. 1 - inner (upper) petals (perianth lobes), standards; 2 - supra-narcular ridge; 3 - stigma; 4 — boot; 5 - beard; 6 - outer (lower) petals (perianth lobes), fouls; 7 - ovary; 8 - a piece of wrapper. © flowers-earth

Perianth lobes are the name given to the “petals” of the iris flower. Among them, there are external lobes - fouls (lower petals) and internal lobes - standards (upper petals). The beard is a strip of richly colored bristles running along the top of the hair. Pistil - has three lobes and a supra-styllicular ridge. Stamens are hidden under the standards and pistil.

Crossbreeding

If everything is clear with the structure of the flower, you can start crossing.

Step 1 - preparation

First of all, you need to decide what you will cross. Using a label, mark the mother plant (which will be pollinated) and the father plant (from which pollen will be taken). (It is better to place the label with the marking under the ovary so that it does not get lost after the flower withers.)

Unfortunately, or maybe fortunately, it is almost impossible to predict the result in advance, but in any case, for crossing it is necessary to take the best specimens with pronounced traits of interest.

In general, the breeder should be interested in the shape of the flower, its color, the number of buds, the timing and duration of flowering, the nature of branching, and the growing power of the variety. An amateur is usually quite interested in the very fact of crossing, and therefore you can start with something simple - try to get a variety of colors of fouls and standards, or mix tall and dwarf hybrids in order to obtain a transitional or connecting medium-sized form.

If breeding work is planned to continue, then it is better to immediately start a separate notebook and record in it a list of crosses and seedlings selected for further experiments, assigning them numbers and letter designations, taking into account the year of crossing, pair number, seedling number.

Step 2 - pollination

In the morning, when the plants have already dried, or in the evening, in dry, windless weather, you must carefully cut off the anther from the paternal iris with scissors. Using a brush, carefully transfer the pollen to the open stigma of the mother flower.

A few important points:

The mother flower is ready for pollination already at the end of the first day of flowering, when its stigma bends (opens). First, the anthers ripen in the opened flower, and only then, after 16 or even 20 hours, the pollen.

When the day is too hot, the stigma dries out and cannot accept pollen. Therefore, it is recommended to carry out pollination at the beginning or end of the day, but taking into account the fact that there will be no rain in the next two hours.

The most viable pollen is considered to be collected on the first day of flowering.

If the iris perianth lobes are corrugated, for easy access to the stigma you can tear off standards and fouls from them.

The follicles and anthers are also torn off in order to protect the flower from pollination by insects.

To increase the percentage of bolls set, it is better to pollinate three stigmas rather than one.

If pollination has occurred, the box will begin to grow; if not, the flower will fade and fall off.

In the event that the mother plant is for some reason not ready for pollination or is not close to the paternal plant, the anther can be stored until the right time in a glass container at room temperature. But it can be stored for no more than eight days.

Step 3 – seed maturation

Next, you need to wait for the pods to ripen (about two months). They should turn yellow-green. But you shouldn’t keep them on the plant for too long, because if the boxes burst, the seeds will scatter. In addition, it was noticed that seeds collected from unripe capsules germinate better.

One box can contain from one to 60 seeds, if these are tall bearded irises, and for dwarf varieties - over 100. At first they have a smooth surface and a honey-brown tint, but as they dry, they wrinkle and shrink by half

Step 4 - sowing seeds

Seed material can be sown either immediately after harvesting or before winter. It is good to sow according to a 10 X 10 cm pattern, burying the seeds to a depth equal to approximately three of their diameters, but not deeper than 1.5 cm.

If the number of seeds is large, it is more convenient to divide the area into four-row beds with a distance between rows of 30 cm and between seedlings of 20–25 cm. The soil for seedlings should be water- and breathable, not acidic.

In unfavorable weather conditions, irises can also be grown through seedlings. In this case, the dried seeds should be placed in labeled bags and stored until February. In February, sow them in bowls in pre-disinfected soil. To retain moisture, you can place a small amount of hydrogel on the bottom of the pots.

To stimulate the seeds to germinate, you need to keep them in the cold for some time. To do this, the container with the seedlings is covered with film and sent to a cool place for one and a half to two months, with a temperature of about +2...5°C, for example, in a refrigerator. Then they place it on a warm, well-lit windowsill, or even better, in a mini-greenhouse and wait for shoots. When it warms up, seedlings are planted outside.

Important rule

In order for the seeds to germinate successfully, the soil in the pots or garden beds must always be moist. Drying out even for one day greatly stops the process of seed germination. But even if all the conditions are met, you will have to wait at least eight weeks for seedlings, with the exception of the seeds of plicata hybrids, which begin to awaken already in the seventh week after sowing. And the germination process itself is extremely uneven, so you need to be patient.

Step 5 - flowering

The last stage is flowering. But it will have to wait. Fully developing plants begin to bloom only in the second or third year.

But even when the plants bloom is not yet an indicator. It is necessary to give irises at least two years of flowering, since only in the second or third year of flowering will it be possible to say whether the result obtained is something interesting or not.

Step 6 - registration

If the resulting cultivar is unique, it can be registered! This must be done through the Russian Iris Society (ROI). But when filling out an application, you will have to fill out a special form in which to note various aspects concerning the new variety, so it is better to print the application form in advance, even before flowering, and fill it out gradually, and not from memory.

IN different countries Festivals, international competitions and bearded iris exhibitions are held annually. The oldest of them is the competition held in Florence, called “Concorso Internazionale dell’Iris”, dating back to 1957.

Australia, America and Great Britain each season award the most interesting new variety of bearded iris in its class a special award - Dykes Memorial Medal, which in Russian sounds like “Dykes Medal”. The presentation has continued since 1927.

The largest number of varieties of bearded iris have been bred in the United States of America (the USA accounts for over half of the registered cultivars); Russia is in second place in terms of breeding activity, followed by Austria and France.

There are more than 30,000 varieties of bearded iris in the world, but none of them have completely black, bright red or pure green petals.

One of the latest achievements of breeders are bearded irises of the so-called “space” group (SA - Space Agers). Their difference lies in the non-standard shape of the beard, expressed by a peculiar outgrowth in the form of a petal - a petaloid (flounce), spoon (spoon) or horn (horn).

The perennial hybrid iris has vegetative and generative shoots. Vegetative ones consist of rhizomes with annual links.

The rhizomes are located horizontally relative to the soil level at a shallow depth, and sometimes extend to the surface. The newly formed links end in a bunch of sessile leaves, which, in the conditions of the Urals, die off annually in late autumn and winter periods.

Generative shoots (peduncles) are branched. Their height depends on the characteristics of the variety. They bear 1 - 10 flowers, and sometimes more. The peduncle lives for one season and dies after flowering and fruiting.

The intensity of growth of annual links and the angle of their deviation from the previous rhizome determine the duration of cultivation of varieties in one place, both for landscaping purposes and for obtaining planting material. The rhizome lives for several years, annually forming new links from the buds with bunches of leaves.

If the central bud of the rhizome is damaged or a peduncle develops from it, then the lateral dormant ones awaken more actively and up to 8 lateral shoots can form. At good conditions cultivation, almost every awakened bud produces a strong annual rhizome.

Most irises are light-loving plants. Many species or varieties vegetate in dark places, but rarely bloom. Different types do not have the same attitude towards the soil, the degree of its moisture, the nature of the reaction and the content of nutrients in it.

Many bearded irises require slightly alkaline or neutral soils, but they also grow well on slightly acidic soils. Their powerful, fibrous root system has a beneficial effect on soil structure. Therefore, for the purpose of cultivation, it is cultivated in one place for 3 - 4 years.

Iris responds well to fertilization. Early spring covering of the soil around the bushes with rotted manure, as well as watering them in the first half of summer with a highly diluted mullein solution, are effective on growth and flowering.

In the absence of manure, plants are fed 2-3 times during the summer. mineral fertilizers(50 g of superphosphate, 20 - 30 - ammonium sulfate and 20 - 30 g of potassium chloride per 1 m2). In early spring, mainly ammonium sulfate and potassium chloride are applied, and in June - August all three types of fertilizers are applied.

During the period of intensive growth and flowering, all garden irises need abundant soil moisture. On light loamy, sandy loam soils that poorly retain moisture, hybrid iris responds positively to watering in sunny weather, which is best done in the evening. During the ripening of fruits and the end of the growing season, the need for soil moisture drops sharply. In the second half of summer, even short-term excessive soil moisture is detrimental, especially for young, immature rhizomes.

Late autumn and in early spring(before the beginning of the growing season), many irises suffer greatly and sometimes die from excess moisture in the soil. Rather, the roots and especially the part that is located near the rhizome are damaged, while the branched ends of the affected roots continue to live for some time.

The bases of the leaves located in the soil and the terminal (apical) buds bearing the peduncle embryo are also easily damaged. Their death is apparently caused by the fact that in the area of ​​the growing zone of the rhizome the activity of vital processes is greatest and even a short-term lack of oxygen when the soil freezes or floods with melt water has a particularly detrimental effect on these areas of the rhizome.

Most garden irises, except the so-called “beardless” ones, do not tolerate closeness well groundwater, but they tolerate prolonged drying out of the soil after flowering without pain.

Family Irisaceae, genus Iris.

In the domestic garden classification of irises there is a clear division into two large groups:

• Bearded irises
• Non-bearded irises

Both are rhizomatous plants!

To avoid confusion, it is necessary to clarify that currently there is no single classification of the Iris genus.

You may have probably heard concepts like

• Rhizomatous irises
• Bulbous irises
• Dutch irises

The Russian Iris Society (ROI) classifies only rhizomatous irises as true irises. The world community believes differently: for example, if you refer to the well-known publication thePlantList, bulbous irises also belong to the genus Iris, for example, Iris xiphium Iris Xifium and Iris junonia Iris Juno.

Russian scientists believe that the attribution of Juno and Xyphium to Irises is erroneous; these are completely different plants, as evidenced by the differences in ontogenesis (age phases) of plants.

In the genus Xyphium, 6 species have been identified, which have been widely used in interspecific hybridization. The results of such selection in different countries led to the appearance of so-called Dutch, Spanish or English bulbous irises on the market.

They are also found in our gardens, although due to climate differences, mainly English hybrids are popular, less often Dutch ones (they are characterized by weak frost resistance), Spanish bulbous irises are practically not found - they are not winter-hardy at all.

Time will tell who is right – the world community or Russian scientists. But for now, planting material from bulbous plants continues to arrive on Russian shelves under the name Hybrid Iris.

Iris setosa

Bulbous irises

The difference between bulbous irises in the root system, storage nutrient organ - bulb, which is also the reproductive organ, consists of 3-7 fleshy scales, not fused with edges, covered with membranous protective scales. The leaves of bulbous irises are lanceolate, grooved, tetrahedral (square when cut), sometimes almost cylindrical. Peduncles are long and thin.

Dutch iris Iris hollandica

English hybrids of bulbous irises are descended from Xiphium latifolium, so many bulbs have numerous, thread-like roots that die off during the summer dormant period.

Besides external difference Bulbous irises differ from rhizomatous irises in their cultivation characteristics. If the rhizomatous ones do not tolerate air humidity and dampness, love the sun, and do not require digging after flowering, then the bulbous ones, for the most part, grow well under light shade, after flowering they require drying the bulbs and storing them in a cool, dry place (care is almost the same as caring for lilies).

Bearded iris

Bearded iris is not a separate species, but the largest group of the genus Iris, uniting different kinds and varieties of irises that have an anatomical feature of the flower structure: on the lower petals there is a strip of fibers of a contrasting color, similar to a wedge-shaped French beard. The beard of hairs is clearly visible on the central vein of the lower petals, but in some species it is also present on the upper petals. Most bearded irises are native to Southern or of Eastern Europe and are classified into sections.

Classification of bearded irises

In addition to specific irises (about 50 species), bearded irises include several thousand decorative hybrids, which in turn are divided into Bearded Irises and Aril + Arilbreds.

The Bearded Irises themselves are divided by height into categories:

• MDB - miniature dwarf bearded, peduncle up to 20 cm, flower diameter 6-10 cm.
• SDB - standard dwarf bearded, peduncle 20-40 cm, flower diameter 8-10 cm.
• IB - intermediate bearded, peduncle 40-70 cm, flower diameter 7-12 cm.
• BB - border bearded, peduncle 40-70 cm, flower diameter 6-12 cm.
• MTB - miniature tall bearded, peduncle 40-70 cm, flower diameter 5-8 cm.
• TB - tall bearded peduncles, 70-110 cm, flower diameter 12-20 cm.

A mark indicating membership in the category may be indicated on planting material(branded packaging with bulbs).

In addition to those mentioned above Russian society Irises are accepted, although very rare:

• Non-Aril-like Arilbreds (AB)
• Arils and Aril-like Arilbreds

Also in catalogs of bearded irises you can see an abbreviation indicating the flowering time:

• E (Early Season) – early date flowering
• M (Mid Season) – average flowering period
• L (Late Season) – late flowering period
• VE (very early) - very early
• VL (very late) - very late
• EML – long flowering

All bearded irises - perennials with a strong rhizome, on average about 1.5-2 cm thick, it is juicy, fleshy, located horizontally underground, and has clearly defined annual thickenings. In some species, the rhizome has a distinct odor (violet aroma). The leaves are usually gray-green, sword-shaped, two-rowed, flat. Peduncle erect, tall, branched. The flower consists of six petals in two tiers: three rise to the top - they are called standards, and three are arched to the bottom - they are called fouls. The shades and colors are very diverse.

Bearded iris - flower structure

The peculiarities of agricultural technology for rhizomatous irises are simple: they love a lot of sunny color (varietal irises are especially light-loving), timely watering, but do not tolerate frequent rains, dampness and high humidity. Soils: well-drained, fertile, with an acidity pH of 6.5-7.5 (neutral or slightly alkaline).

In Russia, hybrids of German Iris, pale Iris, variegated Iris and other species are usually common. And they are usually referred to as hybrid iris Iris hybrida; in total, more than 30 thousand varieties are registered. Flowering periods vary, most bloom in May-June.

It should also be noted that irises have remontant varieties - capable of blooming two or more times during one summer season.

Bearded iris variety ‘Victor Hugo’

Another classification accepted throughout the world according to color scheme, color of iris flowers:

• Iris self Iris is one color - standards and fouls are the same color, the beard may have a different shade
• Iris complete self The iris is completely monochromatic - all parts of the flower, including the beards, are the same color and shade
• Iris bicolor – standards and fouls of different colors
• Iris amoena is a specific two-color iris, the standards of which are white or have a very light shade, the fouls are colored.
• Iris reverse amoena (or darktop) is a two-color iris that has colored standards and white fouls.
• Iris variegata Iris variegata - yellow standards, fouls - red-burgundy or brown.
• Iris bitone Iris is two-tone - the standards are a lighter shade and the fouls are a darker shade of the same color.
• Iris reverse bitone - reverse two-tone - the standards have a darker shade, and the fouls are lighter, all of the same color.
• Iris neglecta Iris neglecta is a variation of the two-tone iris: the standards are a lighter shade of blue or purple, and the fouls are a darker shade of the same color (blue or purple).
• Iris reverse neglecta is another variation of the two-tone iris: the standards are a darker shade of blue or purple, and the fouls are darker. light shade the same color (blue or purple).
• Iris luminata Iris luminata - standards are lighter than fouls (by several shades), on fouls around the beards it is lighter, almost white stripe or colored (yellow, orange or pink), all petals with light marbled veins, fouls - red, burgundy, purple or blue.
• Iris plicata Iris plicata (folded) - on a lighter background, a pattern of small dots or strokes of a different color, often turning into a solid border along the edge of the petal.
• Iris glaciata Iris glaciata - there is no anthocyanin pigment in the color of the petals (red, purple or blue), so they are pure white or carotenoid in color (yellow, orange, pink).
• Iris broken color Irises with “broken color” are varieties with genetically fixed mottling, marbling - white strokes and spots, the color of standards and fouls is very different.
• Iris blend - mixed irises - which have two or more colors in the color of the petals, as a rule, a smooth transition from one color to another (iridescent color).

And a little more terminology that may be useful in growing irises. There are such concepts as:

• Space irises (Iris Space Agers or SA) - these irises are distinguished by the spatial design of flowers, 3B - flowers - when the beards have a continuation of various shapes in the form of a horn, spoon, arrow, or petaloid (petal-shaped formation).
• Corrugated irises - having a pronounced waviness on the outer part of the petals.
• Lacy irises - the lush corrugation along the edge of the petals turns into lace.

Non-bearded irises

These irises differ in that the outer perianth lobes (foli) are hairless, all petals are smooth.

Non-bearded irises are divided into classes:

• SIB - Siberian
• CHR - Chrysographs
• JA - Japanese
• SPU – Spuria
• LA - Louisiana
• CA - Californian
• OT - Others (pseuudacoruses, versicolors, laevigates, setoses and other small varieties not classified into separate classes).

In Russia you can find representatives of not all classes of beardless people. For example, for obvious reasons (climate imbalance), you are unlikely to see California or Louisiana irises in person. But Japanese ones are easy, there are even varieties of domestic selection, for example, ‘Altai Snow Maiden’ or ‘Lilac Haze’. Siberian varieties are popular, mainly in the blue range of flower colors: ‘Ordinary Miracle’, ‘Blue Lagoon’, there is the snow-white ‘Snegurochka’.

Japanese iris (non-bearded)

Non-bearded irises have different flower shapes; some varieties (almost all Japanese) have standards - the upper three petals are not arranged vertically, but, like the foils, are bent far down. In some varieties, the standards (upper petals) are very small and slightly raised, while in others, all six petals are completely identical in appearance.

Uses of irises

Bearded irises are used in garden design in group or single plantings (solitaires), in mixborders, they grow well on rocky slopes, and look impressive in orderly rows along paths. Miniature varieties irises are applicable on borders and mixborders in the foreground, in the design alpine slides, they can be grown in a container (pots).

Most varieties of bearded irises are suitable for cutting and forcing.

When choosing irises for your garden, it is very important to take into account the climatic needs of a particular variety. Iris is a capricious flower that does not tolerate dampness and cold; choose varieties based on frost resistance, locally bred, which are more resistant to cold winters and, most likely, will be less susceptible to various diseases.

Important: In bearded (hybrid) irises, like many other irises, almost all parts of the plant are poisonous (rhizome and leaves), if you eat them by mistake, you can get poisoned - abdominal pain and vomiting. Sometimes there is information about the edibility of rhizomes, for example, Iris Florentine - this is an erroneous opinion; under no circumstances should you eat them. Even the juice of rhizomes and leaves when working with them with bare hands may cause skin irritation or an allergic reaction!

Indeed, the rhizome of the orris root - Iris Florentine - has found application in industry: it is crushed into powder, which is added to laundry detergents, as a flavoring agent in cosmetics(shampoos, perfumes, soaps) for hair care, previously often used in tooth powders, sometimes in folk medicine as an expectorant and decongestant. But no one ever uses it as a food product.
