Species and varieties
In the wild, about 60 species of crossander have been identified. From this impressive list, botanists were able to adapt to the funnel-shaped, as it is also called, wavy, crossander. And also prickly, Nile and Guinean, although the last three items are grown at home very rarely.
The funnel-shaped crossander, in turn, succumbed to taming. By crossing, breeders managed to breed her domesticated hybrid varieties.
The presented species of the bush is the progenitor of many varieties of hybrids. It is found in nature in India. In the natural habitat, the shrub grows to a height of 1 m, and the flower, adapted for indoor cultivation, does not exceed 70 cm. The appearance of the funnel-shaped crossandra inflorescence resembles a dense ear. Flowers on the surface of the bush are distinguished by bright fiery shades in the form of a funnel, the diameter of which is 3 cm.
This variety of flower has the second name "blue ice". The shrub does not differ in compacted inflorescences and magnificent forms. During flowering, bluish flowers appear on its surface, resembling small pieces of ice.
This kind of flower is extremely rare in apartments and houses. It is very similar in form and appearance to its sister, the blue crossander. Although the foliage of the presented variety of the bush is much larger, and the shade of the blossoming flowers is brighter and more saturated.
The birthplace of origin is considered to be Africa. The flower is small in size, its maximum length is 60 cm. The leaves of the shrub are presented in dark green color, slightly omitted in structure. Opening flowers during flowering have five petals. Each individual petal has a different color scheme. Coloring ranges from reddish to pink-orange.
Dwarf variety from African lands. The maximum height of the plant is 13 cm. The leaf plate is decorated with a special pattern that runs along each vein. Inflorescences of the plant are presented in yellow-orange hues. If you look closely at the bract, you can see small thorns, soft to the touch, thanks to which the flower got its name.
When growing crossandra, flower growers mainly use a funnel-shaped species or its hybrids. Below is a list of its most famous varieties, often found on window sills.
The presented indoor flower has compact dimensions, its maximum height reaches 25 cm. The hybrid is bred by American flower growers, it can be found on sale in a wide variety of colors. The most popular is the yellow variety. Variation of the color Red represents the petals of red and pink shades. You can grow this plant at home in a pot or in the garden.
A fairly popular plant variety with compact dimensions, the height of which is a maximum of 30 cm. Due to the small size of the buds, much more blooms on the bush, and the flowering period lasts much longer. A distinctive feature of the hybrid bush is a long life and good health.
Particular attention should be paid to the root system, which is characterized by an increased level of endurance.
Motley novelty. Green leaf plates of the bush are covered with an unusual pattern made of whitish spots and small strokes. Flowers blooming in the crucial period of life resemble sprawling coral-colored fireworks.
Crossandra, by nature, does not accept change very well. After the procedure of planting and transplanting, the plant for a long period gets used to the new capacity with the ground. Quite often, the flowering process is delayed, sometimes the foliage curls into tubules and falls off.
The best time to plant a crossander at home is spring and summer, although breeders planted cuttings all year round. At the same time, noting that in winter the growth and development of embryos proceeds much more slowly.
For independent planting or transplanting a crossander, the grower needs to prepare the soil. It should be porous and neutral. When using universal soil, you need to add a small amount of coarse sand. In the absence of confidence in the purchased soil mixtures, the florist can create the soil for planting on their own.
- In the first version of the workpiece is proposed to mix coarse sandy turf land in the same amount, after adding broken brick.
- In the second case, the grower will have to take 2 parts soil composition for indoor flowers with one part vermiculite and special soildesigned for succulents.
- The third method suggests mixing 2 parts of sheet soil and peat bog with one part of sand and sod land.
Do not forget about the drainage system. It can be made of expanded clay, crushed pebbles or bricks.
Having familiarized yourself with the properties of the soil required for planting a crossander, you can begin to study the process itself in the form of step-by-step instructions.
- The soil prepared for planting must be calcined. Pour the pot for heat treatment with boiling water.
- At the bottom of the treated tank, drainage is laid out, a small amount of planting soil is poured on top.
- It is important to note that the flower also needs some preparation for planting, therefore, 3 days before the appointed event, the plant must be stopped watering. The old soil is completely dry, so that the crossander will be released from the old pot. A lump of earth on the root system needs to be gently shaken off.
- The taken plant is located in the center of the new tank, its roots are distributed in the interior of the pot.
- Next, you need to fill the gaps between the walls of the tank and the plant itself, while trying not to hook and injure the delicate and delicate roots of the crossander.
- After planting, the flower should be watered and sprayed on the crown of the bush. In this case, moisture helps the plant to take root in a new place without stress.
Crossander require careful attention to the conditions of his content.
In the process of growing a plant, the florist must remember its tropical roots, which indicates the love of Crossander for a warm environment.
In general, the temperature in the room where crossander is grown should not fall below +18 degrees Celsius. If necessary, it can be transferred to another, slightly cool room, but for a short time.
In the summer season, Crossandra feels comfortable on the sunny side of the window, under diffused light. Direct sunlight causes severe burns to the flower, which are clearly visible on the leaf blades of the bush and on the petals of the buds.
If there is a lack of lighting, the leaves of the crossander will begin to curl, and the flowering process will stop. Quite often, a similar problem occurs in the winter.
When purchasing a crossander in a store, a florist should think about transplanting a plant from the transport soil into natural soil for its subsequent cultivation. The time between the purchase and the transplant procedure should be approximately two weeks for the plant to undergo adaptation. After crossander has mastered the new conditions, it can be transplanted.
The past acclimatization will help the flower to take this procedure less painfully.
Florists should know that a young crossander is transplanted once a year. Adults representatives every 2 years. Transplantation is carried out in the spring. Pruning a plant is done with the arrival of heat and before winter holidays.
Crossandra's resting period is winter. At this very time, there is no need to feed her with useful substances. Otherwise, instead of buds, she will begin to dissolve a huge number of leaves. With proper care, plant enrichment with vitamins and nutrients should begin with the advent of spring. Top dressing is done once a week. Fertilizers can be organic and mineral, although mineral fertilizing is much more convenient and profitable.
Crossander's watering procedures are extremely scrupulous. The better the plant is moistened, the longer and more magnificent the flowering process will take place. Watering itself is entirely dependent on the time of year. In summer, you have to moisten the soil more often, as the soil dries very quickly. With the onset of cold weather, watering should become moderate, in winter the plant's need for moisture is reduced several times. It is optimal to water once every two weeks, but do not forget to check the soil. Overflow of the flower and overdrying of the soil should not be allowed.
In general, it’s a pleasure to look after a crossandra. With the right approach, she will respond with bright flowering, reminiscent of fireworks.
The procedure for propagating crossandra at home occurs in two ways: by planting seeds and dividing the cuttings.
Way seed propagation it is used extremely rarely, only if it is not possible to separate the stem from an adult flower. In addition, growing crossander from seeds is considered a rather troublesome and lengthy process. Next, we suggest that you familiarize yourself with step-by-step sowing instructions.
- Seeds must be sown on the surface of the prepared loose soil. For successful development, you should maintain an air temperature of about 22 or 23 degrees. The soil composition can not be watered, it is enough to spray slightly.
- As soon as the leaves appeared, seedlings must be transferred to cups with water.
- When transferring the seedling, the pinching procedure is performed. This measure is aimed at increasing the deciduous properties of the bush.
- When the seedlings stretched to 10 cm, they must be transplanted into pots.
Division of cuttings - The most common and very convenient way to propagate crossandra in a room environment. It is resorted to by most flower growers who grow cross-country at home.
- In an adult flower with side, you need to separate a small stalk.
- From the bottom of the handle leaflets are cut off, then the baby is transferred to a container of water.
- When the stem has an independent root system, it is transplanted into a pot. The flower grower should give a new planting some time to adapt, and then proceed to the standard procedure for growing the plant.
Diseases and pests
Growing crossandra, some gardeners are faced with various ailments that can affect healthy flowering plants.
- Leaf mold disease most often occurs due to large irrigation. For treatment, it is necessary to temporarily reduce water procedures. A piece of mold cut off. For prevention, the plant will have to be treated with a fungicide. Until Crossandra recovers, it must be isolated from other indoor flowers.
- Insects attack crossandra extremely rarely. But with prolonged growth in low humidity, aphids or spider mites can start. If the grower managed to capture the initial appearance of these pests, the plant will be enough just to rinse with water. The main thing is not to overmoisten the soil composition of the flower during the shower. If the grower late identified the occurrence of pests, and they managed to multiply, you will need to apply insecticides.
As a preventive measure in the room where crossander grows, it is necessary to maintain high humidity.
- Beginning growers when growing crossandra may face the problem of falling leaves. This is due to moisture deficiency and drying out of the soil composition. The leaves of the crossander do not fall off immediately, at first they fade, which is already considered a signal for increasing a humid environment.
- Some gardeners are faced with the lack of flowering crossandra. To solve the problem, it is enough to transfer the flower pot to a place with good lighting, or organize additional artificial lighting. In addition to the lack of lighting, the reason for the lack of buds may be improper pruning of seedlings.
In addition, the age of the flower affects the flowering process. After four years of life, crossandra decreases flowering time and splendor.
- Some gardeners complain that the leaves of the grown crossandra turn red. The solution to this problem is to rearrange the flower pot away from direct sunlight, as this color change indicates burns to the leaf plates. To restore the natural shade of foliage, crossandra needs to be away from bright light for some time.
- Other gardeners have the problem of blackening leaves. This color change mainly occurs in winter, when the temperature in the room where the flower is contained falls below the permissible limit.
In the absence of sufficient watering, the foliage falls on the crossander. An appropriate solution is to increase the fluid both in irrigation and in the surrounding air.
How to care for cross-country at home - look at the video.
The origin, appearance and features of the content of crossander
It is believed that the first crossandra was brought to Europe in 1817 along with tea from the island of Ceylon (now it is Sri Lanka). Although in the wild this plant is also common in the African, Asian tropics and Madagascar. A flowering bush (about 1 meter high) has chosen a moist and hot jungle. There, in spots of sunlight, bright orange and red crossandra blooms inflorescences all year round.
Crossandra blooms without interruptions all year round
And in the cold gloomy climate of the tropican mourned. She could not bear the dry air of the houses and agreed to grow only in greenhouses, where conditions close to natural were created. And only after a century and a half, breeders paid attention to the solar resettlement. In 1950, the cross-country variety Mona Wallhed was developed, suitable for growing at home. Since then, new hybrids of this wonderful plant have appeared. They appreciate it for its long and magnificent flowering, original inflorescences and picturesque foliage. Crossandra was not among the ten most popular plants, she is still a rare guest in our apartments. But deserves more attention from flower growers.
Russian florists noticed and fell in love with the solar crossander
Fiery petals appear on vertical inflorescences with peculiar caps that resemble salutes. For this resemblance, the inhabitants of Sri Lanka gave Crossander the name - fireworks of flowers.
Crossandra is a fast-growing bush (up to 70 cm tall in the room), straight stems are dressed in greenish or brownish bark.The leaves are large (average 8 cm) oval and pointed at the end, with a glossy sheen and sparse villi. The veins are well distinguished, in most varieties the color of the leaf plate is dark green, in some it is mottled. Even without flowers, the crossander looks elegant.
Crossander's flowering is a festive phenomenon comparable to a firework
And when it comes to flowering, she is simply charming. At the ends of the shoots appear high (up to 15 cm) cobs of peduncles, buds open gradually from the lower tier. Flowers most often in different shades of flame in shape resemble an asymmetrical funnel, their petals seem to wilt. There are species with turquoise and lilac inflorescences. At home, crossander easily sets fruits. If the flower spike is not removed after withering, after a while you will see how the self-sowing mechanism works. When the fruit, which contains four seeds, ripens, Crossander shoots them. And, falling to the ground, it explodes quite noisily. Crossandra blooms from an early age, with good care for about six months, starting in spring. The heyday can be extended for the winter, providing the plant with additional illumination, but it is better to give it a rest.
Crosandra not only blooms magnificently, but also enjoys fruiting at home
To the question: is crossander easy to grow, you will get different answers. For a sophisticated florist, this plant is picky and easy to care for. A newcomer, it may be difficult to adapt to the habits of Crossander. Although she does not require anything supernatural, only that, or even less, is what her ancestors are used to. Crossandra wants warmth, high humidity and loves living in close proximity to other, of course, tropical flowers.

Varieties and varieties of enchanting plants
About fifty crossandra species were found in the natural environment. The funnel-shaped (or undulate) variety and its hybrid varieties were mainly adapted to room conditions. Far less often, flower growers grow prickly, Nile and Guinean crossander.
- Nile Crossandra (also called red) was born in Africa. This is a low (60 cm) shrub with slightly pubescent dark green leaves. Flowers with five petals fused at the base of different shades of red: from brick to pink-orange.
- Prickly crossandra is also an African native. At a low bush it has large (12 cm) leaves, decorated with a silver pattern along the veins. Inflorescences are yellow-orange. On the bracts, small soft spines are clearly visible, thanks to them the variety was named.
- Crossandra Guinea - a rare plant in home floriculture. This is the smallest variety, its growth is not more than 30 cm. Flowers collected in spikelets at the top, unusual delicate purple color.
- Blue Crossandra (or Blue Ice) is not very dense, compared with other varieties, inflorescences and not so lush flowering. She has light bluish flowers.
- Crossandra Green Ice is a rare species. It looks like blue, but the flowers have a more intense color, and the shade is turquoise with green.
- The funnel-shaped Crossander is the progenitor of most cultivated plant varieties. It grows naturally in India and Sri Lanka. In freedom, the bush stretches up to 1 meter. The room variety is usually above 70 cm. The inflorescence is a dense ear, the flowers of fiery shades are funnels (about 3 cm in diameter).
The most famous varieties of funnel crossandra:
- Mona Wallhed - the oldest variety bred by Swiss breeders, it was he who gave the start to breeding crossander in home floriculture. This is a compact and dense bush with bright foliage and orange-scarlet flowers. But the main thing is that this crossander is more tolerant of the climate of the apartment. Simply refers to dry air and lower temperatures.
- Orange Marmalade is one of the new varieties. More resistant to changes in conditions of detention and resilient. On a sprawling bush, orange-orange inflorescences are formed.
- Nile Queen is another crossandra variety that can be called unpretentious. His flowers are terracotta red.
- Hybrid Fortune - the most popular among gardeners. The bush is small - about 30 cm. And the height of orange-red inflorescences reaches 15 cm, due to this there are more buds, and flowering is longer. In addition, this variety has a long life and good health. It has a more robust root system.
- Crossandra Tropic is a compact (up to 25 cm) hybrids of different colors, bred by American flower growers. The most famous variety is yellow, Flame with salmon flowers, Splash - with petals of different intensities of yellow-pink color, Red - red with a pinkish tinge. These crossders are grown not only as indoor plants, but also in the open field as annual plants.
- Variegate (motley) crossander is one of the new products. Its green leaves are covered with an original pattern of white spots and strokes. Flowers of a coral shade.
What does crossandra need? (table)
|Spring||Intense, but slightly diffused. A suitable place for crossandra is at the east or west window. On the south side at noon, the plant will need shading, especially in the heat.||High, from 70%. ||Moderate, approximately +20 degrees. Crossandra has a good attitude to fresh air, but is afraid of drafts. Ventilate the room, protecting the plant from temperature extremes.|
|Summer||Moderate and higher. It is better to 25 degrees, but it is possible and higher to +28. |
In summer, if possible, keep the crossander on a glazed balcony. But the plant should not be taken out to the garden; wind and rain can damage it.
|Autumn||Permissible direct sun. Can be placed at the south window. With a decrease in the longitude of the day, turn on artificial lighting. Correct and long-lasting illumination during the dormant period is a guarantee of flowering in the future.||Medium, 50-60%, at lower temperatures. |
Above average, 60–70%, in a warm (+20 or more) room.
Humidify the air.
Keep the flower away from radiators.
|Room, + 20-25 degrees.|
|Winter||The temperature is slightly lower, + 16-18 degrees. Crossder does not tolerate less than +12. |
Cover the plant from drafts.
Cramped but comfortable
Crossandra is a very friendly plant. Florists noticed that she feels better not alone, but in the close company of other flowers. Put next to the crossandra the same lovers of moist air and heat - begonias, crotons, fittonia, ferns, arrowroots, calatheas - and it will be easier for you to take care of the indoor jungle. By spraying some, you moisten others. Without unnecessary efforts, you will provide your pets a tropical microclimate at home.
Crossandra will be easier to care for if she is surrounded by other plants with similar habits.
Transplant flower fireworks
Crossandra is not very fond of change. The plant takes a long time to get used to the new pot, can delay with flowering, twist and discard foliage. Therefore, a fiery flower is transplanted, if the roots have braided over the whole earth and peeking from below, growth has slowed due to the fact that the soil is depleted. Then resettle the crossander in the spring. Make transshipment as high as possible while maintaining an earthen lump.
The new crossandra pot should only be slightly larger than the old
The next crossandra pot must be selected 2-3 cm wider in diameter than the previous one. Extensive she does not need. In a large volume of soil, it will grow roots, then the aerial part, and the flowers will appear later or not at all. In a large pot, water will linger, and this is fraught with decay of the root system. The material of which the tank is made is not so important for the crossander. Both plastic and ceramics are suitable for her. And the number and diameter of drainage holes are important. The more of them, the better. Excess water should easily leave the ground.
There must be a drainage layer in the crossandra pot
Prepare cross-soil with porous and moderately fertile, neutral or slightly increased acidity. For example, plant it in universal soil, you can add a little coarse sand or chopped moss. Or try to make the soil mixture according to one of the recipes:
- mix sheet and soddy ground, coarse sand equally, add vermiculite or a bit of broken brick,
- into two parts of leaf and sod land, half - river coarse sand and humus,
- 2 parts of any soil for indoor plants, 1 each - vermiculite and soil for succulents,
- in two parts of leaf and peat land, add turf land and sand in one part.
For drainage you can take expanded clay, small pebbles, crushed brick (necessarily red).
- Prepare and steam or calcine the soil mixture, drainage, and pour boiling water over the pot.
- Put drainage at the bottom, on top of it is part of the soil.
- Two or three days before the transplant, stop watering the cross-lands to dry the ground, it will be easier to pull out and keep the earthen lump.
- Get the crossander from the tank, separating the earth from the walls with a knife or spatula, inspect the roots.
- Rotten and dry cut. Clean the few extreme processes from the ground.
- Treat the root system with growth stimulants (Epin, Zircon).
- Set crossandra's earthen ball in a new pot, spread loose roots.
- Carefully fill the gap between the lump and the walls with new soil.
- Seal it gradually, being careful not to hurt the roots.
- Water the plant and spray its crown. Humidity helps to settle down faster.
- Place the transplanted crossander in its usual place.
After the purchase
If you bought a flowering crossandra, wait with a transplant until the inflorescences wither. And then try to replace almost completely the soil. Save only the one that holds tight to the roots. To stimulate flowering, crossander can be treated with special preparations that are not always useful, so it is better to transplant it into fresh soil.
Transplant the blooming crossandra that you brought from the store after the inflorescences have withered
Transplant the crossander bought without flowers in 1-2 weeks. Moving from the store is stress, transplanting too. Let the flower get used to the new home.
In the wild, tropical crossandra blooms twelve months of the year and does not deplete. In our climate, its seasonal rhythm has changed. At lower temperatures, less intense lighting, flowering takes more power. Crossandra needs to fully relax in the winter in order to blossom in the spring. Therefore, care for the plant at each time of the year is your own.
Crossander, who is properly looked after by shiny leaves and flower hats
Watering and feeding at home
During active development, from spring to late autumn, water the crossander generously. To replenish the forces spent on flowering, she needs a lot of moisture. Moreover, the water should be demineralized (settled, filtered or boiled) and slightly warm. Drying of the soil in the pot during this period has a very negative effect on plant health. Especially in hot weather. As soon as the earth at the roots has dried, the withering of the aerial part will begin. In advanced cases, if Crossander is dehydrated all day, she may die.
You forgot to pour your crossander in the summer heat. And when they remembered, its leaves had already withered and sagged. Resuscitate the plant. Urgently remove the flower in the shade, fill a large container with water and put a pot there, and sprinkle the crown abundantly. After a few hours, Crossander will straighten the leaves again. After that, remove the flower pot from the water, let it drain.
But at the same time it is not worth making a swamp from the soil. Stick to the middle ground: keep a balance between waterlogging and drying out.
During the crossing, the crossander needs abundant watering and top dressing.
Closer to winter, begin to reduce watering. Crossandra has faded and goes on an economical mode of life. She no longer needs so much moisture. The cooler the air, the less the plant wants to drink. In winter, it is watered on average once every 10-14 days. However, the frequency can vary, it all depends on the well-being of the Crossander. And it’s better not to add a little water than to pour.
Potassium and phosphorus are useful for flowers, and an excess of nitrogen interferes with the formation of buds.
Crossander in his prime is supported by fertilizers. Top dressing begins in March (if the flower was only transplanted, then 2 months later), it is applied onto the watered soil once every 7-10 days. Any mineral complexes for indoor flowering plants are suitable. Crossandra lovers note that she perceives well the fertilizers of the Uniflor and Pokon series. But it is not so important which brand, pay attention to the composition, which is always written on the package. For high-quality flowering, the plant needs potassium and phosphorus. In winter, crossander is usually not fed, or limited to 1 time per month.
Well-groomed crossander with pleasure blooms without any tricks. And even in winter in a warm and bright room, she strives to bloom. Fans note that the plant produces peduncles several times during the season, flowering waves are 2-3 or more. To extend it, it is necessary to completely completely, to be more exact, a couple of leaves, remove the spikelet after the top has faded. Then there will be new flowers.
Crossandra willingly blooms if he gets everything he needs
However, occasionally flower growers complain that Crossandra is naughty and does not bloom. Here are the main reasons for this behavior:
- the plant is planted in a too voluminous pot and is busy building roots and greenery,
- the flower did not rest in the winter
- there is not enough nutrition or a lot of nitrogen in feeding, it contributes to the development of greenery,
- the bush was not cut, it did not form a new shoot that blooms,
- Crossandra is weakened due to improper care or conditions: little light, low humidity, irrigation is not adjusted, etc.
The last to open the buds on the top of the spikelet, after they wither, it is necessary to cut off the entire inflorescence
Analyze what the crossander wants, correct the mistake and wait for the flowering. By the way, variegated varieties are usually more capricious, and older plants bloom worse.
The buds on the variegate crossander - a prize for a skillful and caring grower
Rest period and pruning
Crossandra, living in the wild, has no rest period. But in our latitudes, her habits have changed. In autumn, the plant slows down its development by hibernating. The flower grower must organize the rest correctly: limit watering, stop feeding, lower the temperature of the content, and proportionally reduce air humidity. In winter, spraying can be replaced by wiping the leaves with a damp cloth. But the duration of daylight hours is desirable to maintain. Crossandra will be grateful for the additional lighting with LED or phytolamps. If there is no backlight, put the plant on the southern windowsill.
Crossandra can bloom all year without a break, but it is better to give her a rest in winter
After wintering (in February-March) the crossandra bush should be put in order. Spring haircut is carried out before laying the buds, it rejuvenates and heals the plant. Weak, overgrown branches and stems are removed. Healthy shoots cut or pinch about 4-5 cm above a pair of leaves. After such a haircut, the crown will become more magnificent, the tops, and, therefore, there will be more flowers. Cuttings left after pruning can be rooted to get new plants.
Mowing should be done even after flowering, uncut spikelets take away strength, but if you want to get seeds, leave them

With a significant lesion, the plant must be discarded and treated with the fungicide of its neighbors.
- Do not water the soil.
- Keep an eye on the temperature, while lowering, warm the roots and limit watering.
- Ventilate the room. Fresh air interferes with the development of rot.
- Sterilize soil and drainage.
- Quarantine new plants.
- If everyone is softened and darkened, it’s too late to treat.
- If most of the roots are white and springy, heal.
- Rinse off all soil under the tap.
- Cut off all affected roots with a knife. Remove wilted leaves and shoots, shorten the trunk.
- plant in a new pot and fresh soil.
- Spill a solution of fungicide (phytosporin, carbendazim).
- Place in a warm and bright place, without bright sun.
- Do not water until the formation of a new shoot begins.
- Inspect the plant regularly to detect the first signs of pest infection and take action on time.
- Keep your leaves clean.
- Humidify the air and ventilate, pests, for example, spider mites actively multiply in dry and stuffy rooms.
Spray it with preparations that contain permethrin.
New crosses can be grown from cuttings and seeds. Cuttings are a simpler method and guarantee the receipt of the same plant as the parent. Seeds collected from home-made crossandra do not guarantee that a similar specimen will grow. After all, room crossders are usually hybrids. And only the producer knows what will turn out from the purchased seeds.
It is most convenient to combine cross-trimming and cuttings. Cut tops are well rooted in spring. But in summer you can also propagate the plant.
- Cut apical cuttings 10-12 cm.
It is logical to carry out trimming of the crossandra and reproduction simultaneously
For rooting cuttings need a light and not very nutritious soil
If the cuttings took place in early spring, in late summer young plants may bloom for the first time
Some gardeners say that crossandra cuttings are easily rooted in water, into which activated carbon is added, it protects from rot. If young roots are not allowed to grow strongly, up to a maximum of 1 cm, the plant later safely adapts to the ground. However, other crossandra lovers claim that water roots form poorly. Perhaps we are talking about different types of plants. Unpretentious hybrids of new varieties root better.
Many flower growers successfully grow flower-fireworks from seeds. At home, if you do not cut the peduncle after withering, you can get the fruits of crossander. Each contains 4 seeds. On sale there are also seeds of varietal hybrids.
- Soak the seeds for 2 hours in a solution of zircon or another phytostimulator.
Inside each pod there are 4 seeds
Crossandra seeds are sown in a loose substrate
Crossandra seeds usually germinate in a couple of weeks
Picking and transshipment of young plants stimulates root growth
My crossandra is constantly blooming, and growing quite quietly. After the February pruning, it bloomed a month later and has not stopped since then. The window is southeast, the sun through the blinds, watering almost daily, especially when it's hot. I almost do not spray it, I feed it every 10-14 days with fertilizer for flowering plants and every 2 months I have a talker of ash. Absolutely non-whimsical plant))).
I grew orange crossandra for three years - I bought a sprout from my granny. It bloomed almost always, it grew very quickly, I pruned it periodically. It was unpretentious - in the summer on the balcony, in winter on an unheated loggia with very rare watering. And this spring, she died, attacked something like a virus, the leaves began to turn black with spots, then the trunk. I had to throw it out, was not subject to resuscitation. For me it was not a problem plant.
I always root crossander in the water; it gives roots not quickly, but one hundred percent. A glass with cuttings is also placed in a greenhouse, since the crossander has the ability to quickly wither. The roots appear in three to four weeks. After planting in the ground for some time I keep in a greenhouse. Crossander’s water roots adapt very quickly to the soil, literally the next day you can see through the walls of the glass how they grow.
Seeds ripened in my red crossandra, when I touched them with a glance, and then an “automatic burst” hit me, they shoot loudly and painfully!
Marinahttp://frauflora.ru/viewtopic.php?f=183&t=1631&s> Dutch plant, bought a little. Over the year she grew up, pleased. The plant is problem-free, blooms without ceasing, the peduncles are longer every year, the flowering is more plentiful. You just need to pick off the faded flowers from the spikelet and fertilize it from chlorosis. Well and correctly pinch it.

My crossandra, feeling fine, stands on a warm windowsill. Interestingly, not so long ago I started to practice lower watering, since there is free time, so the crossandra experienced two such waterings and she woke up and even got lateral buds, of course, maybe I at my own expense and deceive myself, maybe this is the work of the approaching spring. She makes me happy.
The flower itself is very beautiful, only moody, it constantly needs moist air, during the day I spray it 2-3 times, we just need to try so that the water does not get on the spikelet. When it bloomed, I cut off all the inflorescences and cut the bushes themselves. First I put the cuttings in the water with fertilizer “Rainbow” for 1 day, and then I stuck it in the ground and put it under the hood, I need to pour water into the saucer. Thus, the stalk should be around 1 week. After you can remove the jar, but transplant to a more adult should not yet, you must wait until the first green leaf appears. But then it can already be planted in an adult plant. And the more often you pinch, the bush will be more magnificent, but of course you need to look again at what place it is better to pinch and that there are no spikelets. My flower blooms almost constantly, but in general it begins to bloom at the age of several months.
My crossandra is already 3 years old, cuttings (cut) in February, until there are no buds, top dressing with organics, the pot is cramped, we bloom from April to November ...
I also got a crossandra, I bought a stalk rooted here at a subsidiary in late February and since the beginning of April it makes me happy. All guests are thrilled! Replanted the truth 2 times, growing fast and drinking a lot :)
Crossandra should not be afraid of leaf fall. It is beautifully overgrown with new foliage. When my first leaf fall began, I cut and rooted the cuttings with a fright. As a result, there was a bald frame that I regretted throwing away, so in the summer it pleased me like that, and now it’s falling over again.
Variegate crossandra crossandra pungens variegata is blooming right now. Foliage is something divine! All winter I stood not on the window, but on the table on the whatnot, there wasn’t much light, I would say even a little, but the leaves were still very beautiful variegated, no worse than those when I stood in a bright place. Its growth rate is slow, like many variegated plants.
Bright as a firework, the crossander deserves more attention from flower growers. Difficult, at first glance, caring for this tropical plant in practice is not so difficult. If your collection has lovers of high humidity and heat, Crossander will become a good neighbor to them. Put such flowers near to simplify leaving, and admire a variety of foliage and inflorescences.
