Corydalis

Corydalis


The herbaceous corydalis (Corydalis) is a member of the Poppy family. The scientific name of this plant is derived from the Greek word for "helmet", this is due to the shape of the flowers of the corydalis. This genus unites about 320 species. The greatest diversity of species (about 200) is observed in the territory of Central and Western China, as well as the Himalayas, where Corydalis grow at an altitude of 3000–5000 meters above sea level. These plants began to be cultivated relatively recently, or rather, in the 19th century. They were previously imported from Central Asia, the Himalayas, Siberia, Tibet, but most often from China. Today they are quite popular among gardeners, as well as, for example, dahlias, tulips and phloxes. And all due to the fact that such a flower is not only very beautiful, but also resistant to frost and diseases, undemanding to care, and it also has medicinal properties.

Corydalis features

The flowering Corydalis plant is a perennial and an annual. The rhizome of such a plant is quite massive, it is located at a rather great depth and consists of branched processes. On individual shoots, the formation of rounded tubers is sometimes observed, inside which there are nutrients. The height of erect shoots can vary from 0.15 to 0.45 m. At the base of the stems there are 2–4 fern-like leaf plates of a dark green color with a bluish bloom. Leaves can be twice or three times complex, the shape of the lobes is triangular or rounded, and each of them has its own petiole. The formation of racemose cylindrical inflorescences at the tops of the stems is observed in mid-April. The inflorescences include 5–35 long flowers, which can be colored pink, purple, white, purple or yellow. Flowers have corolla length from 1.5 to 2.5 centimeters, pointed sepals are small, and bracts are relatively large. All flowers have rather long spurs, inside of which there is nectar. It can only be obtained by those insects that have a long proboscis. The fruit is an oblong box with small glossy black seeds inside. Each seed has a fleshy growth that ants simply adore. As a result, ants can drag these seeds over a rather long distance.

Corydalis begins to grow in March. Its flowering begins after the soil warms up to 3-4 degrees. The flowering period is approximately 20 days. Seed ripening is observed in June, after which the dying off of the part of the plant that is above the ground occurs. In landscape design, these plants are most often grown with other primroses, for example: crocuses, muscari, chionodox, galanthus and early tulips.

Planting corydalis in the open field

What time to plant

As a rule, corydalis planting material is sold at a time when its tubers are dormant, or rather, from the second half of June to September. It is during this period of time that it is recommended to plant this crop in open soil. The acquired planting material must be thoroughly examined. You should choose dense and juicy tubers. The tubers of the Central Asian species of this plant can be slightly dried, it does not harm them.

When choosing a site for planting, you should pay attention to which group the species of Corydalis you grow belongs to. So, for example, experts advise Chinese, mountain and alpine species to grow in an open, illuminated area, with well-drained sandy loam soil, while it should be located on a hill or hill. And forest species are recommended to be planted in a shaded area with loose humus soil. It must be necessarily neutral or slightly acidic.

Landing rules

There is nothing difficult in planting and growing the corydalis. Before planting, the site must be prepared. If the soil is dense and excessively heavy, then during digging it is necessary to add fine gravel or crushed stone to it. It should be remembered that when moisture stagnates in the soil, rot forms very quickly on the roots. To avoid this, you should make sure that excess liquid drains off the site quickly enough.

The depth to which tubers should be planted directly depends on their size. Large tubers should be planted to a depth of 10 to 15 centimeters, and small tubers should be buried 5-7 centimeters. The planted tubers need abundant watering.

Crested Crested Care in the Garden

When growing a corydalis in the garden, it should be watered, weeded, fed, loosened the soil surface and protected from pests and diseases in a timely manner. But it should be borne in mind that different types of care requirements and preferences may differ.

How to feed and water

In the first weeks of spring, when the corydalis begins to grow, as a rule, the soil is rather moist from melt water, so the plants will not need to be watered. After the earth dries out, the plants will need to be watered systematically. It should be noted that alpine and desert species should be provided with moderate watering, since they react negatively to stagnant moisture in the root system, while a short drought does much less damage to the plant. It must be remembered that any of the corydalis species reacts extremely negatively to stagnant water in the soil, in this regard, the land on the site must be well-drained. When the bushes are watered, you need to loosen the surface of the site, while removing the weeds. To reduce the number of weeding, watering and loosening, the surface of the site must be covered with a layer of organic mulch.

Only forest species of corydalis need feeding, while compost or leaf humus should be added to the soil during digging before planting. Also in the spring, you can mulch the surface of the site with organic matter.

After the bushes have faded, their parts located above the ground turn yellow over time, and their dying off is observed. To remember where they grew, you need to mark each bush by sticking a peg next to it. This culture is distinguished by a fairly high resistance to frost, so it does not need shelter for the winter. However, it should be borne in mind that the Chinese Corydalis can die if the air temperature drops below minus 23 degrees.

How to transplant and propagate

It is recommended to transplant this primrose during the period of its rest. But even during the flowering period, the corydalis bushes tolerate this procedure quite well. However, when transplanting, a part of a flowering bush located above the ground can come off quite easily, in which case the tubers will begin a dormant period earlier than usual. They move the bushes to a new place along with a lump of earth.

For the reproduction of such a plant, seeds, tubers, and also the method of dividing the rhizome are used. On the rhizomes, tubers are formed only on the corydalis of Kashmir and Bush. You can divide the rhizome in the spring, as well as from the middle to the end of the summer, and do this during plant transplantation. When dividing a bush, it should be borne in mind that each delenka must have a renewal bud and a part of the rhizome. When planting delenoks, they are buried in the soil by 5-15 centimeters (depending on the size of the tubers), while a distance of at least 10 centimeters should be kept between the holes. But it should also be borne in mind that this breeding method is not very popular with gardeners.

Unripe corydalis seeds should be sown. So, they should be painted black, but the boxes should still be green. Try to pick the pods in time, otherwise, when they are fully ripe and open, the seeds will spill out onto the surface of the site, where ants will quickly drag them away. The seeds remain viable for 7 days, so there is no need to tighten them with sowing. Seeds are sown in containers, which must be filled with a moistened substrate. Then they are transferred to a shaded place and make sure that the soil mixture is always slightly damp. Seedlings can be planted in the garden after spring comes. Corydalis grown from seeds bloom for the first time after 2–4 years (depending on the species).

Diseases and pests

Corydalis are highly resistant to disease, so they rarely get sick. If there is stagnation of water in the root system, then this can cause the development of a fungal disease. Any culture can become infected with a viral disease, no matter how badly or well you care for it. Bushes affected by such a disease should be removed from the soil and destroyed, and the area where they were grown must be spilled with a solution of potassium manganese, which must be strong enough. To cure a plant affected by a fungal disease, it must be sprayed with a fungicide solution.

Of the pests, mice and moles are dangerous to the crested. To get rid of them, bait with poison must be placed on the surface of the site in several places.

Types and varieties of corydalis with photos and names

Experts divide a large number of crested species according to environmental requirements that determine the type of agricultural technology. Forest species are the most unpretentious of all perennial corydalis species, for example: Bush's corydalis, smoky-leaved, large-flowered (giant), Magadan, low, deceptive (doubtful), intermediate, narrow-leaved, dense (Hallera), Caucasian, Kuznetsova, Marshall, Malka, bracts and placed (Turchaninov). For the cultivation of these species, it is recommended to choose areas with clay or sandy loam soil saturated with leaf humus and humus. They grow best in grass in a clearing under deciduous trees, in a garden under fruit crops, as well as in permanent flower beds.

The most popular varieties are Haller's corydalis (dense), for example:

  1. Beth Evans... The flowers are painted in a delicate shade of pink, while the spur is white.
  2. Prasil Strain... It is a mixture of varieties with flowers colored in various shades from salmon and pink to red.
  3. George Baker... The flowers are deep red, almost cherry-colored.
  4. Dieter Schacht... The flowers are pale pink.
  5. Highland Mix... Inflorescences are painted in a smoky pinkish-blue color.
  6. Munich Form... The flowers are colored coral red.
  7. Nettleton Pink... The inflorescences have a deep pink color.

Perennial species of the Himalayan deserts, highlands and foothills are less adapted for cultivation in mid-latitudes. They received a conditional name - mountain species. These include: Wilson's crested, Darvaz, Ledebour, Narinyan, Popova, rut-leaved, Severtsova, Emanuel, Kashmir, holosteel, large-spine, Maracandan, Pachosky, dissected-leaved, glaucous and Shangin.

Perennial rhizomatous species include sulfur-yellow, yellow and noble corydalis. Annual species are much less often cultivated, for example: touch-me-not corydalis and evergreen.

Not so long ago, highly decorative species originating from the Chinese region of Sichuan began to be cultivated in Europe, namely: the corydalis high and winding. The most popular are the following varieties of Corydalis sinuous:

  1. Blue Panda... The leaf plates are colored in a light green-blue hue. The flowers are azure, the spurs are bent.
  2. Pearl Leaf... The color of the leaf plates is violet-red. On the shoots at the base of the leaves, there are spots of dark red color.
  3. China Blue... In winter, the foliage is green-brown. The length of the azure-greenish flowers is about 31 centimeters.
  4. Balang Mist... The color of the flowers is bluish.

Corydalis: planting and care in the open field

Flowers do not require any special skills to grow.

How to plant

Select the seed and place. Seeds lose their germination within 5 days. Therefore, they are sown immediately after harvest:

  • seed pods are harvested when they are still green
  • peat and sand are poured into the container
  • small black seeds are evenly distributed over the surface, sprinkled with sand
  • after moistening from a spray bottle, cover with a film.

Seedlings and first leaves appear only in spring.

By the time of planting, the seedlings will get stronger. The landing is done when the threat of night frosts has passed, and the earth warms up to + 15 ° C.

If the crop is planted with tubers, then they do it from July to autumn. At this moment, she is at rest.

Attention! Finding the location of the tubers after the plant has bloomed is difficult. Therefore, it is marked with a peg in advance.

When the ground part is dry, the place is carefully dug up. The tubers are removed, transferred to a new place.

Deepen depending on the size of the planting material. For large tubers, dig a hole up to 15 cm deep, for small ones, 7-10 cm is enough. There they will stay dormant until next year.

Landing site, soil

The flower grows anywhere: near water bodies, on rocky hills. In the flowerbed, it coexists among perennials: host, lilies, early bulbous. When they just bloom, the growing season of the tuberous variety ends.

Lighted areas and partial shade are suitable for planting. The main condition is good drainage. Water should not linger - the roots quickly rot.

A ventilated glade without constant drafts is the optimal place for planting a corydalis.

The soil is chosen fertile neutral. Loose clay or sandy loam soil is suitable. Compost or humus is added to sandy soil before planting.

The culture takes root well under fruit trees. In this case, the leaves are not removed from the site for the winter. This is an additional cover in case of severe frosts, and food when the leaf is overheated.

In spring, the flower is one of the first to break through to the surface. Therefore, the garden from last year's foliage is raked out so as not to damage the seedlings.


For growing indoors, only one species is suitable - dense corydalis. To do this, a medium-sized tuber is placed in a pot with soil to a depth of no more than 5 mm, then the plant must be placed in a dark and cool place, with an air temperature of no higher than 8 ° C for 9 weeks.

It is necessary to ensure that the plant does not dry out, but at the same time beware of excess moisture. During flowering, the comfortable temperature for a herbaceous shrub is 18-19 ° C. At the end of the growing season, stop watering and move the pot to a cool place again. Corydalis and all of its many species have long been highly valued by gardeners for their unpretentiousness and ease of care. The decorativeness of this plant is in no way inferior to the most capricious ones.

Its indisputable advantage is that it will not be difficult to grow a flower from seeds, and charming flowers will delight with their flowering with the appearance of the first rays of the sun.
