EPHEMEROIDS EPHEMEROIDS

(ephemeroida), perennial herbaceous plants, which are characterized by autumn-winter-spring vegetation. They bloom in early spring. In summer, above-ground shoots die off completely, leaving only underground storage organs with buds - bulbs, tubers, rhizomes. Typical for arid regions where they rest during periods of drought (species of tulip, sedge, bluegrass bulbous), as well as for forest-steppes and broad-leaved areas. forests where they use a wet and light period before the leaves bloom on the trees (Siberian scilla, species of corydalis, buttercup anemone).

Perennial herbaceous plants that have the ability to suspend life processes during drought (summer) and begin growth and development in favorable time, i.e. They are characterized by autumn-winter-spring vegetation. Mainly bulbous plants. So, in spring numerous types of tulips and goose onions bloom. In summer, the aboveground part dies off completely and no traces of the plant are visible, and the bulbs rest in the ground. Some bulbous ephemeroids (e.g. colchicum, saffron) bloom in autumn.

Not everywhere the climate is conducive to long-term flowering of plants. In some regions it is so unsuitable that it lasts only a couple of months, or even weeks. In such places, ephemerals and ephemeroids often grow. We'll talk about them in more detail.

Ephemera - what are they?

Full usually takes a very long time. Only seeds can break through the ground for several months, not to mention further development. There are plants that live for a year or two, but oak and eucalyptus die after thousands of years.

There are species that simply don’t have that much time. These are ephemera. They are typically found in areas with harsh conditions where access to light or nutrients is severely limited for most of the year. To survive in such an environment you need to try. Some plants use thorns, others are small, and others have simply learned to do everything very quickly.

Ephemera are annual herbaceous plants. In one short season (from two weeks to two months) they manage to grow to the state of an adult plant, bloom, bear fruit and die. And the seeds that fell to the ground will germinate next year, completely repeating the experience of the “parents”.

Typical ephemera are African malcolmia, oak grouse, spring stonefly, some poppies, woodlice, Tal's rhizome, anthurus, etc. Most of them have small roots and unbranched stems. The leaves are small and not very dense, so that photosynthesis proceeds as intensely and quickly as possible.

Where do they meet?

Ephemera usually represent vegetation of deserts, semi-deserts and steppes. In such places the weather is favorable only for short periods. In deserts they occur during precipitation. Then rivers appear on lifeless lands, and their valleys are filled with flowers and herbs. As soon as the hot sun dries up the rivers, the plants will disappear.

Ephemera make up 80-90% of all vegetation in Africa. They are found on the Arabian Peninsula, in Kazakhstan, in the steppes of Ukraine, in Russia and many other countries of the world.

They do not always inhabit deserts and steppes. Selected species They are also common in deciduous forests, such as oak forests. Low-growing plants are not very comfortable in them due to the lack of sunlight. Ephemera usually appear here in the spring, when the trees have not yet acquired leaves. They develop intensively and complete their life cycle by the time lush crowns will block their access to the sun.

Ephemeroids

The vegetation of deserts and other places with difficult climates is also represented by ephemeroids. Unlike ephemerals, they live for several years and in unfavorable periods they only stop their growth.

Perennial ephemerals can be found growing side by side with ephemeral plants. In addition, they are widespread in meadows, mixed, coniferous and deciduous forests. Among the ephemeroids: scilla, kandyk, anemone, colchicum, tulips, crocuses, yellow goose onions, bulbous bluegrass.

They can grow stems and leaves slowly, but only flower and bear fruit during a short growing season. Favorable conditions for this usually occur in early spring or autumn. After flowering, their above-ground organs die off, but tubers, bulbs or rhizomes remain underground, from which the above-ground parts will grow again next season.

Thal's rhizomet

This ephemera is also called cutting. With the exception of Antarctica, the plant is distributed on all continents. It is found in Canada and the USA, in the southern and central regions South America, in Northern and Southern Africa, throughout Eurasia and Australia.

The rhizome lives only six weeks and is capable of self-pollinating. Due to these properties, the plant is often used in laboratories for various studies, like fruit flies or rats. It was even grown on space stations and was planned to be grown on Mars and the Moon.

Oak groats

Like the rhizome, the kibble belongs to the cabbage family. It grows up to 20 centimeters. The leaves of the plant are oblong and located close to the ground. At the end of the long and straight stems there are small pale yellow flowers, collected in inflorescences.

Krupka blooms from April to June. Its seeds and stems are often used in folk medicine for cleansing the blood, kidneys, treating bronchitis and pleurisy. It grows in meadows and fields, on rocky and sandy slopes. Krupka is found in Ukraine, Belarus, Central Asia, Siberia, the Far East and the European part of Russia.

Scilla

Scilla is often called the “blue snowdrop” due to the strong similarity of the plants. This is a typical ephemeroid that lives for several years. often blue, but may be white or yellow. It blooms for about two weeks in April, with some species appearing in the fall.

Scilla is found in Africa, Asia and Southern Europe, Crimea, and the south of the European part of Russia. The flower grows in mountainous areas or on shady, well-moistened plains. Despite the fact that its homeland is the southern regions, it tolerates frost well.

The flowering of early small bulbous plants marks the long-awaited arrival of spring. For each crop it is fleeting, only about two weeks. However, their assortment is wide enough for us to have the opportunity to admire the picturesque carpet for at least a month, selecting the ephemeroids according to the order of flowering. The bulbs, tubers, and rhizomes of these plants are small in volume, which allows for fairly close planting near other perennials or shrubs. The ground part dies off quite quickly after flowering and does not spoil the appearance of the plantings.

Crocus Remembrance

In general, crops are unpretentious and durable, they can long time do without the attention of the gardener, however, for a successful start, a number of conditions must be met, first of all - good drainage selected landing site. Best time planting - from mid-August to mid-September.

More are acceptable late dates, if allowed weather. The bulbs are planted to a depth of 4-7 cm, the planting distance is from 7 cm. Newly acquired planting material should be carefully inspected, removing all soft and rotten bulbs, as well as those that are too light and dried out.

Corydalis dense

Iris reticulum George and Pushkinia

After flowering, the leaves are not cut off; they must dry out on their own - this is necessary for the full development of the plant and flowering next year. When the nest of bulbs thickens, it is dug up and planted. This is not always necessary, only when flowering deteriorates or in order to take over the crop large area. It is important not to skip the time of digging, but to do it when the leaves are dry but still noticeable, otherwise it will be difficult to find the bulbs in the soil later.

Vesennik Cilician

Kandyk Siberian

Pests and diseases are rare, but voles, shrews and moles can significantly damage plantings. Spring whiteflower (Leucojum vernum) blooms from the end of April, the flowers are quite large, solitary. Prefers dense, moisture-absorbing soils, where it quickly grows in large colonies. On dry, poor soils it blooms and reproduces very weakly.

Vesennik (Eranthis). Two species are grown - winter spring grass (E. hyemalis) and Cilician (E. cilicica), as well as their varieties and hybrids. It blooms very early, right out of the snow. The dazzling yellow flowers open only in sunny weather. When choosing spring flowers, you should keep in mind that its nodules dry out quickly.

Therefore, you must either plant them immediately after receiving or digging them up, or store them in slightly moist peat (perlite, sphagnum) and a perforated bag until planting.

Iridodictium (I. reticulatum) and histrioides (I. histrioides) are represented in cultivation by varieties and hybrids, many of which work well in our climate (Katherine Hodgkin, George, etc.).

They bloom in the second half of April. Large bright flowers very impressive on short stems. They are durable only in warm, well-warmed-up summer places exposed to the sun. To the nutritional value of the soil special requirements do not present it, it is only desirable that it is not sour. Kandyki (Erythronium) are distinguished by their rare grace and originality, but are quite rare in gardens.

Crocus Violet Queen

Bulbs are also rare on sale. They are “naked” - devoid of integumentary scales, fragile and, as a result, very vulnerable during storage and transportation. However, careful digging and shipping in slightly moistened peat or sphagnum is quite possible, so do not be afraid to order kandyks from specialized nurseries or from collectors.

Now we already have at our disposal a number of varieties of European kandyk (E. denscanis) and decorative forms Caucasian (E. caucasicum) and Siberian (E. sibiricum). The Caucasian one blooms first, immediately after the snow melts, and the other two species follow it, in the second half to the end of April. The least whimsical kandyk of toulumnense (E. toulumnense) blooms later, at the end of May. Best place planting - partial shade. The soils are similar in structure and nutritional value to forest soils.

In "native" garden soil It is useful to add leaf humus or simply half-rotted litter. If kandyks are planted under trees, then fallen leaves are not removed. It is better not to dig up nests of bulbs unless necessary and generally disturb the plants as little as possible. Crocuses, on the other hand, are widespread and popular. From these alone you can create a multi-colored meadow that blooms for a whole month.

Crocus hybrid Blue Peter

The earliest are the golden crocus (C. chrysanthus) and its varieties and the Tommasini crocus (C. tommasinianus). After them, the majority of varieties of hybrid origin bloom. For planting, choose a bright place with loose, sufficiently nutritious soil.

The division of corm nests has to be carried out earlier than in other small-bulbed corms, since the mother corm produces daughter corms in large quantities, and with a lack of space for development, they become smaller. Small daughter bulbs bloom worse. Such a nest is dug up in early June, the bulbs are sorted, dried and stored in a dark, dry, ventilated room until planting.

Snowdrop (Galanthus nivalis) is one of the most unpretentious ephemeroids. If planted in a shaded part of the garden on loose, moderately nutritious soils, it can grow for years without any care. Withstands sodding and deep planting of bulbs without compromising flowering. Blooms in early April, from under the snow. In years with particularly heavy snow cover, you can see snowdrops appearing in bloom directly in the melting snowdrifts.

Crocuses and Chionodoxa

At the same time, they have yellowish leaves, devoid of chlorophyll, that have grown in a dark snow captivity. In the light they quickly turn green, and the plants continue to bloom as if nothing had happened. The terry form of Flore Pleno reproduces much more slowly than the typical one. Siberian scilla (Scitta sibirica) is the most common of the scillas; it blooms in early May. The flowers are bright blue, noticeable from afar.

It has a Major form (commercial name Spring Beauty), characterized by larger flowers. It grows well in the sun, in partial shade and in fairly strong shade, but in the latter case the flower stalks become lodged. Absolutely unpretentious, easily naturalized, spreading throughout the garden by self-sowing. The earlier one is Mishchenko's scilla (S. mischtschenkoana), it blooms in mid-April.

Spring whiteflower

The flowers are light blue, in inflorescences of 5-7 pieces. Following it, the graceful two-leaved scilla (S. bifolia) blooms. It has medium-sized star-shaped dark blue flowers, 12-15 per peduncle. And at the same time, another, very elegant scilla is blooming - Rosen's scilla (S. rosenii). Her blue flowers have an original shape: the petals are curved back, like those of a cyclamen.

Puschkinia scittoides, according to its specific name, resembles a scilla, the flowers are pale blue in inflorescences of 10-12. Prefers a bright planting site and is unpretentious. It is better to plant nests of bulbs every 5-6 years. Chionodoxa blooms in mid-April. The most common varieties are Chionodoxa luciliae (C. luciliae) and giant (C. gigantea).

Chionodoxa Lucilia

Chionodoxa hybrida

They have fairly large, wide-open flowers. different shades blue, pink, lilac and white. Chionodoxa Sardensis (C. sardensis) blooms with smaller flowers, collected in inflorescences of 7-9 pieces. Plants develop better on sunny places. Unpretentious, they can do without digging and dividing nests of bulbs for years.

They easily spread throughout the garden by self-sowing, and in places where they are planted together with scillas they form hybrid forms. For flower growers who love order in their flower beds, Chionodoxes, with their ability to grow wherever they want, cause certain difficulties. Corydalis (Corydalis) are even more freedom-loving than Chionodox. This is a true find for natural style gardens.

Once you plant the dense corydalis (C.solida, C. halleri) in a flower garden, over the years you will get flowering meadows both at the original planting site and far around it. On sale there are selected natural forms and varieties with flowers in pink, lilac, purple, two-color, as well as white and yellowish. Self-seeding of plants produces a wide variety of color variations. Flowering lasts from mid-April to early May, longer in cool weather. Corydalis bract (C. bracteata) is a larger species, creamy yellow flowers in a large raceme.

Scilla bifolia

Scillas, corydalis and crocuses

Corydalis dense Drops of Claret

Oak anemones

Very interesting, but rare on sale are the Far Eastern species of corydalis - dubious (C. ambigua) and Turchaninova (C. turchaninovii). This miniature plants with sky-blue flowers collected in a loose, short raceme. Corydalis prefer a semi-shaded planting site: under trees, shrubs, between large perennials. Digging is never required.

Anemone Green Fingers

If you need to do this, then you must not miss the moment - the ground part of the corydalis disappears very quickly, after which it is difficult to find small nodules in the soil. Corydalis nodules dry out easily, so they are planted immediately after receiving.

If you still have to preserve the tubers for some time, they are sprinkled with a slightly damp substrate (peat, sphagnum), placed in perforated or paper bags and kept in a cool, dark room. Among the rhizomatous ephemeroids, the oak anemone (Anemonoides nemorosa) has the greatest varietal diversity.

There are varieties in blue and lilac tones: Robinsoniana, Atrocaerulea, Royal Blue, etc. Among them, Abendhimmel is distinguished by especially large flowers of a smoky amethyst color. Pink varieties have a peculiarity - the color appears over time. A newly blossoming flower may disappoint you with just a hint of... pink color, such as the Tilo variety. But as it blooms, the tone becomes more and more saturated, so the light pink Marselina at the beginning of flowering ends flowering almost crimson.

Anemone Marselina

Among terry varieties unsurpassed in growth vigor and flowering stability ancient white variety Vestal. Among oak anemones, there are also varieties with white-green flowers of unusual shape: Monstrosa, Green Fingers, etc. Pale-yellow shades are added by varieties of lipsiensis anemone (Anemonoides x lipsiensis), a hybrid between oak anemone and buttercup anemone. The flowers of the Pallida and Schwefelfeuer varieties are somewhat smaller than those of the oak forest anemone, but the plants grow faster.

Anemones form neat dense clumps with graceful carved leaves; they bloom from the beginning of May for two weeks or more. During flowering, the leaves are practically invisible behind a continuous carpet of delicate flowers. Plants should be given a place in moving shade; the soil should be loose and moderately nutritious.

It is useful to enrich it with leaf humus and mulch the plantings with rotted leaves. The right time for planting is the entire second half of summer, early autumn. Planting material usually consists of pieces of rhizome with several buds. They are stored in a slightly moist substrate.

Anemone lipsiensis Schwefelfeuer

When planting, they are placed horizontally, at a depth of about 3 cm. If suitable conditions have been created, then further care may not be necessary at all. The plants do not require rejuvenating division, and it is better not to disturb them with replanting. Note that varieties of oak anemone can retain leaves until August in cool summers.

Anemone Vestal

Oak anemone and strange butterbur

If the white-green varieties of oak anemone have exotic look, then they still look like garden plants. Physochlaina physaloides, on the contrary, gives the impression that it was brought to us from outer space.

In early spring, dark purple shoots appear, then they are covered with purple-violet leaves, densely pubescent buds appear and, finally, an inflorescence of several bell-shaped lilac flowers appears. Then nothing interesting happens - the stems turn green, stretch out, lie down and dry out by mid-June. But for the sake of a stunning spring benefit, it is worth placing the bladderwort in the garden.

It is planted during the dormant period (second half of summer, autumn) in sections of rhizomes, shallowly. Rhizomes tolerate shipment and storage in the substrate well. The location is preferably light, with almost any soil, but not too wet. You just need to take into account that on rich soils the active growth of bladderwort will have to be limited.

Physalis bladderwort

Canadian sanguinaria (Sanguinaria canadensis) blooms in the second half to end of April. Shape with simple flowers good in large clumps in shady places with moisture-absorbing soils, where flowering can last about 10 days. Plants actively explore the surrounding space with the help of spreading rhizomes.

Self-seeding is often observed. After flowering, the clump is decorated with grayish-green leaves of unusual shape, which dry out by mid-June. The double form grows more slowly, but blooms more spectacularly and lasts longer.

Plants take root well when planted in pieces of rhizomes with several buds in the second half of summer, in September. Transplants are not required, and if necessary, they are performed during the dormant period, carefully removing the fragile rhizomes.

Man knows more than 300 thousand plant species. Some of them grow in unsuitable conditions. One of these plants are ephemeroids. To survive in a difficult environment, they had to use tricks and develop special devices. What are ephemeroids? You will find the definition and examples in our article.

What are ephemeroids?

Ephemeroids are perennial herbaceous plants, but this is not their peculiarity. They have learned to live where there is access to water or sunlight It is not eaten all year round, but only in certain seasons. In such conditions, many plants die, because they need these elements regularly to maintain the body.

Ephemera are, in their own way, unique plants. They adapted to difficult conditions thanks to a short growing season. When there is enough light and water, they grow and bloom rapidly. With the onset of an unfavorable season, their ground parts dry out and fall off. The underground parts (tubers, rhizomes, bulbs) remain to grow new shoots next year.

Ephemeroids have very little time to develop. Sometimes plants only have a couple of weeks left. Their underground organs contain a lot nutrients. They accumulate there to nourish the plant during hibernation.

Ephemeral plants also have similar properties. But, unlike ephemeroids, this annual plants. In a short growing season, they manage to produce seeds and then die off completely.

Where do they grow?

Ephemeroids are inhabitants of deserts, steppes and semi-deserts. There is always a lack of moisture there, and the hot sun literally burns out all living things. But in spring it often rains, and the light is soft and gentle. At such a time, poppies appear in the steppes, astragalus grow in rocky deserts, and tulips bloom on the sands of Turkmenistan.

From September to November, climatic spring begins in the Atacama Desert. There may be no precipitation there long years, therefore it is considered one of the driest places on Earth. But due to the influence of El Niño, some areas are sometimes irrigated by downpours, and lifeless spaces are covered with colorful flowers.

You can also find ephemeroids in ordinary forests. In dense deciduous forests there is enough moisture, but on the contrary, there is not enough light. Ephemeroids grow in oak forests and other groves. They appear when there is no foliage on the trees in order to make the most of solar energy.

Depending on the time of appearance, they are divided into spring and autumn ephemeroids. Example autumn plants the colchicum serves, autumn crocus. Spring flowers are: tulips, crocuses, snowdrops, goose onions.

Anemone

Anemone or anemone is an ephemeral plant from the ranunculaceae family. The flower is distributed throughout the Northern Hemisphere, even covering some areas of the Arctic. About 170 species of anemone are known, most of which are poisonous.

Anemones are neat large flowers with at least five petals. They come in yellow, red, white, blue and pink flowers. They usually grow in the tundra, on rocky hills and slopes, in steppe meadows and on shady forest edges.

Goose onion

It is also called yellow snowdrop, yellowflower, viper onion or gooseberry. In April, the plant appears on mountain slopes, steppes and forests. It has yellow flowers with elongated petals and tall narrow leaves.

The height of the goose onion is approximately 30-40 centimeters. It does not grow as single flowers, but in small groups. It was once eaten boiled and was also used to treat asthma, ulcers, and wound healing. Yellowflower is found in North Africa and in the temperate zone of Eurasia, for example, in Ukraine, the Far East and Central Asia.

Snowdrops

They are the ones who announce to us the arrival of spring, appearing even before the snow has completely melted. The snowdrop or “milk flower” is common in the South and Central Europe, in Asia Minor, on the Black Sea coast. About 16 of its species grow in the Caucasus.

Its flower consists of six petals, which are arranged in two circles. Unlike many other plants, it does not reach up towards the sun, but is lowered towards the ground. The snowdrop dies in May. The duration of its flowering depends on the area where it grows, as well as the altitude above sea level. Thanks to its unpretentiousness, the flower is often grown in garden beds. However, some of its species are listed in the Red Book and are considered endangered.

Ephemera

Ephemera- an ecological group of herbaceous annual plants with a very short growing season (some complete their full development cycle in just a few weeks).

These are usually very small plants of deserts and semi-deserts or steppes. They develop intensively, bloom and bear fruit during the wet period (spring or autumn) and die off completely during the summer drought.

Some ephemeral plants found in Russia: Spring stonewort ( Erophila verna), Oak Krupka ( Draba nemorosa), Cornea crescent ( Ceratocephala falcata), Prolomnik northern ( Androsace septentrionalis), Malcolmia africanica ( Malcolmia africana), desert alyssum ( Alyssum desertorum).

There are also perennial plants similar to ephemerals - ephemeroids, in which only the above-ground part dies.
