Plant Clerodendrum, belongs to the family Verbenaceae, of the order of Anadivine. Evergreen and deciduous shrubs and trees represent this genus. In nature, this plant is most often found in tropical Africa, South America, and Asia. In total, this genus includes about 400 species.
To cultivate such a plant began several hundred years ago. However, as a potted flower, Clerodendrum started to grow relatively recently, but it has already become trendy among designers and gardeners.
Brief description of cultivation
- Flowering. It starts in June and ends in the first autumn weeks. Flowering fragrant Clerodendrum observed almost year-round.
- Illumination. Necessary bright, but diffused light (window, Western or Eastern orientation, with the South sill of the Bush, should be protected from direct sunlight).
- Temperature regime. During the growing season and flowering temperature should be from 18 to 25 degrees, and during the rest period ― from 13 to 15 degrees.
- Irrigation. It should be plentiful. Moistening of the soil mixture is carried out after drying its surface.
- Air humidity. She should be tall. To do this, in the spring and summer every evening, moisturize the Bush from the spray, and in winter remove it away from the heating devices.
- Fertilizer. Feeding is carried out from the second half of spring to the last summer days regularly one every 15 days. To do this, use a mineral complex fertilizer for flowering plants.
- Period of rest. When will the flowering in autumn and winter?
- Clipping. At the very beginning of active growth.
- Transplantation. The plant is transplanted at the beginning of the growing season. While the young Bush should be transplanted regularly one once a year, and an adult plant ― 1 every 2 or 3 years.
- Reproduction. By cuttings and by seed.
- Pest. Whitefly, aphids and spider mites.
- Diseases. Rot and chlorosis.
Features of Clerodendrum
The plant has the following features:
- Precious green leaf plates of Clerodendrum whorled or opposite-lying simple heart-shaped with rough “quilted” surface. Their length varies from 20 to 30 centimeters, and the edge can be solid or serrated. At the bottom of the flexible stems quickly lignified. The terminal racemes or corymbose inflorescences consist of very spectacular flowers with long stamens.
In most species the flowers have a butterfly shape, however, clerodendrum Benga and
- Philippine inflorescences superficially similar to the unusual form of the bouquets.
The leaves and flowers of most species exude a smell. At the same time all kinds of a different flavor.
- The most popular among flower growers are 2 types, namely: brilliant and Thompson.
- However, at home also grown and other species.
- Through pinching and pruning the Bush can be given a different form, or rather, Bush, basket or standard.
- Take care of such a flower is not difficult, because it is characterized by simplicity and endurance, and it is beneficial and has a beautiful aroma.
Care of Clerodendrum at home
Since Clerodendrum is a tropical plant, for it to grow and develop within the norm, the conditions should be as close to natural as possible.
The flower needs much light, but it must shading from the direct rays of the sun. Best fit for his window of the Western, Eastern or southern orientation.
During the growing season, the optimum temperature is from 18 to 25 degrees. Also, in winter, during the rest period, the Bush should be in a cool place (no more than 15 degrees).
The plant needs high humidity, in this regard, every evening in the spring and summer it needs to be moistened from the sprayer, for this well-settled water is used. In winter, Сlerodendrum put away from working heating appliances.
Watered flower abundantly and is used for soft water. However, the top layer of the substrate in the pot between watering must necessarily dry. During the rest period, the amount of watering depends on the temperature in the room, namely, the colder, the less need to moisten the substrate. However, in any case, do not allow complete drying of the earthen coma.
Feeding is carried out one time in 15 days from the second half of spring to the end of the summer period. To do this, use a compound mineral fertilizer for flowering houseplants. In autumn and winter time to feed the Сlerodendrum is not necessary.
Depending on the type of flowering plant begins in June. Also, the flowering of Сlerodendrum ends around September. It looks awe-inspiring when on the bare stems of type Thompson at the beginning of the spring period formed bracts white, and then they appear beautiful crimson flowers, reaching a diameter of about 25 mm. Flowering flower fragrant lasts for almost all year, and clerodendrum beautiful ― from June to September, while paniculate inflorescences are consisting of flowers of purple hue. Clerodendrum blooms so effectively that its flowers will want to see again.
This plant must be regularly cut every year at the beginning of the growing season. The first step is to remove all weak and dried shoots, after which all the stems are shortened by 1/3. If it fails to carry out trimming, the young lateral stems will grow and ramify more active. Namely, they have formed inflorescences. As a result, proper pruning promotes more lush flowering.
Pruning is also necessary for the formation of the crown. So that this flower grew a Bush, it is required in the spring during pruning very much to shorten the stems. Otherwise, you will need to install support for them later. With the correct pruning, Bush can be shaped like a tree.
To create a stamp form, cut all the shoots, leaving only the one strongest, it is shortened at the height of 0.5–0.7 m. The stems growing in the area of the top need to be pinched, thanks to this it will be possible to form a beautiful crown. Sprouts growing on the stem below the head, it is necessary to cut on time.
Periodically replace the old substrate in the pot with a new plant, for this transplant is carried out. Also, this procedure is carried out if the root system becomes very close in the pan.
Transplantation is carried out at the beginning of the growing season after the Bush is cut. While the flower is young, it should be transplanted regularly once a year, and more adult bushes subjected to such a procedure one every 2 or 3 years.
Substrate for clerodendrum takes fertile and slightly acidic (pH 5-6). For planting, you can take the store soil mixture, which should be poured a little sand. You can also prepare an earthen mixture with your hands, for this, connect coarse sand, peat, clay and leaf soil while taking them in equal parts. Before the transplant, it is necessary to disinfect the fresh soil mixture with steam, oven or microwave.
The new pot should be a couple of centimeters taller and more abundant in diameter than the old one. At the bottom of the first make a right drainage layer height of about 30 mm, then by transshipment transplanted flower in a new pot, while trying to keep the earthen lump whole.
All the voids in the container need to be filled with fresh soil mixture, after which the Bush must be watered. If the flower over time will need support, it should be installed immediately during the transplant, as then if you start to stick into the substrate stick, it can injure the roots.
Growing from seeds
Seeding is carried out in the last days of February or the first ― March. To do this, fill the container with a soil mixture consisting of sand, turf soil and peat, and evenly distribute the seeds on its surface.
After that, the crops are removed in a mini-greenhouse and provide them with good lighting. Regularly ventilate them and moisturize the surface of the soil mixture promptly. With proper care, the first seedlings should appear after 6-8 weeks.
Also in pots, in diameter reaching 11 centimeters, you can plant tree seedlings. Once the seedlings take root and start to grow, they are gradually accustomed to the conditions of your adult bushes.
Reproduction by cuttings
In that case, if you already have clerodendrum, it can be propagated by cuttings. Once in the spring, the Bush is trimmed, you will have a crop of shoots, which can be used as cuttings. Roots on cuttings in spring and summer appear quite quickly, while rooting is carried out in the water.
When the cuttings take root, they are transplanted into separate pots, in diameter reaching about 70 mm, after which they are covered with a glass cap. Make sure that the surface of the soil mixture is always moist. After the root system of the cuttings will be formed completely, and it will grow new stems and leaves, it, along with a lump of land neatly transshipped into a new container of greater size (diameter about 90 mm).
In this pot, the clerodendrum will grow until spring (it is no longer necessary to cover it with a cap). After one year from the beginning of rooting, the Bush should be transplanted by transshipment into a larger container, in diameter reaching 11 centimeters, while the soil mixture should be used the one that is suitable for an adult plant. During this year, the stems on the Bush need to pinch at least two times, thanks to this flower will be lusher.
Pests and diseases of clerodendrum
Clerodendrum is most often harmed by insects such as whiteflies and spider mites. As a rule, the whitefly can be found on the lower surface of the leaf plates, and on the front side of the sheet due to the presence of feces of the pest appears shiny plaque, which is called honeydew or pad.
If the flower settles spider mite, then see it with the naked eye you can not. About its presence on the plant will tell you the white dots that appear on the wrong surface of the foliage, as well as on the Bush, you can find a fragile web.
To get rid of both the tick and the whitefly, clerodendrum can be treated with an insecticide. For example, take 1 liter of water and connect it with one ampoule of Aktellik, the resulting solution operate the plant. If necessary, you can spend four spraying with a break of three days.
Clerodendrum does not bloom
Often beginners in the cultivation of clerodendrum are faced with such a problem as the lack of flowering. In this case, often the cause of this problem is straightforward and at the same time unexpected. If you understand that Clerodendrum refuses to bloom because of improper care, and try to fix it, then soon all the problems are resolved by themselves. Most often, clerodendrum does not thrive if in the winter he was in the wrong conditions.
Is it possible to make clerodendrum bloom? So in the spring to see the beautiful bloom of this plant, it is necessary that in the winter it was cool. Immediately after the Bush will fade, conduct a gradual reduction of irrigation, and it is removed in a relatively cold place (air temperature is not higher than 15 degrees). Best of all, the culture winters at a temperature of about 12 degrees, while watering should be rare and scarce, but it is impossible to allow complete drying of the earthen coma.
The rest period lasts about 6-8 weeks, during which time the plant has time to relax and stock up on forces for a new period of vegetation and flowering. After the Bush will have young shoots, gradually resume regular watering, cut it and if necessary, then transplant. Put the clerodendrum in its permanent place and start feeding it again regularly.
Remember that the soil mixture in the pot should always be fertile. Often, the Bush refuses to bloom and if it is not transplanted for a very long time. Moreover, the plant may not thrive due to poor lighting, in this case, it also sometimes crumble already formed buds.
Clerodendrum turns yellow
In that case, if the yellowing of the foliage is observed in the spring and summer, it may be due to the rather rare and scarce watering. To fix this, spend watering more often or pour more water into the pot and remember that there should be some amount of liquid in the tray all the time.
The appearance of yellow spots on the foliage may be associated with the development of chlorosis. In this case, an iron-containing agent can help clerodendrum.
In that case, if the leaves fall in the cold season, it can be quite a natural process. This can be observed in all deciduous plants. As a rule, the leaves gradually turn yellow and fly around during the autumn-winter period. However, if the flight of leaves is observed in the warm season, it is likely that the flower is not properly cared for or it needs to be moved to another place.
Types with photos and names
This type is most popular among gardeners. It is represented by deciduous lignified vine, which has a thin smooth stem. Large dense leaf plates of dark green color are alleged, on their surface veins are visible. The length of the leaves is about 12 centimeters, and their shape is oblong-ovate pointed.
On the front surface of the foliage are spots of irregular shape, which can be painted in darker and lighter shades. Swollen white flowers have a red Corolla, they are part of the axillary loose brushes. In indoor conditions, this species is characterized by rapid growth, it is propagated exclusively by cuttings, and flowering lasts from March to June.
This evergreen shrub has curly stems that adorn the leaf plates almost round shape with a heart-shaped base, and they have a rough edge and an oblong, pointed apex. The length of the plate reaches 8 centimeters and width 6 centimeters. Short axillary inflorescence corymbose or racemose flowers consist of scarlet-red hue. Flowering lasts almost throughout the year.
This species differs from the others in that it has a sharp but pleasant vanilla-Jasmine smell, in the evening it becomes even stronger. Gardeners grow this species is relatively rare, though it is quite easy to care for, as it is undemanding in care.
Already in the second year of life on the Bush, there are spectacular whitish-pink inflorescences with a diameter of about 20 centimeters, they include flowers of a pinkish shape, in diameter reaching from 20 to 30 mm. They look very impressive against the background of dark green full leaf plates.
This evergreen vine has rapid growth, and its length can reach up to 200 cm Form dark green leaf plates broadly. The final few-flowered loose inflorescences consist of flowers that are very similar to butterflies, thanks to the blue stamens thread-like shape, resembling antennae.
The side and upper petals have a blue color, while the barely discernible lower leaf is painted in purple or bluish-purple color. This type of pruning can be given the form of a tree or a Bush.
This shrub is evergreen and reaches a height of about 200 cm on the surface of the stems has pubescence. Broadly ovate leaf plate is also pubescent; at length, they reach up to 20 inches and have deep teeth on edge.
Dense corymbose apical inflorescences, reaching a diameter of about 80 mm, consisting of Terry or simple flowers of white with a pinkish tinge on the outside, the smell is similar to citrus and violet. Flowering lasts almost all year round.
Clerodendrum of Wallich, or Prospero
Still this kind of name the bride veil, or Cleopatra’s tears, or a veil of the bride. It blooms very richly snow-white blossoms, which consist of wonderful flowers of unusual shape. The Bush is compact and very elegant, its stems are tetrahedral, and they are decorated with lanceolate leaf plates of dark green color, which reach 50-80 mm in length, the edge is wavy.
This type is different from the rest of its high demands on the growing conditions. For healthy growth and development, it needs high humidity and a special light day.
This evergreen shrub has a tetrahedral section of stems that reach a height of 3 meters. Large glossy heart-shaped leaf plates are located on long petioles of a reddish hue, on the surface there are villi. Lush flowering is observed in June–September.
