The Kutrov family includes the genus hoya (lat.Hoya), in which there are up to 200 species. Distributed in Australia (tropical part), in some parts of India and in the Malay Archipelago. The genus name was given to the plant in honor of Thomas Hoya.
The genus is represented by evergreens with creeping and climbing shoots. Leaves are oval, ovoid, leathery, fleshy; axillary inflorescences. Corolla of five members, round, fleshy. The flowers form an umbrella. Crown of five thick, convex, dissected columns.
Indoor hoya is a very unusual ornamental plant. They grow in warm as well as temperate and cool rooms - they carry dry air well. For good growth, the hoye needs to be supported.
Read more about growing hoya below.
Home hoya loves bright lighting. The best place to grow hoya is considered to be east or west windows. If the plant is grown on the south side, then it is better to disperse the direct rays at midday. If the plant has just been purchased, then it should not be exposed directly to the sun - it must be taught to the sun gradually in order to avoid burns. The same is done after winter, or with plants that have not been in the sun for a long time. Growing hoya on the north side, you can not wait for its flowering.
In summer, the optimal temperature for flowering and development of hoya in room conditions is 22-24 ° C. In winter and autumn, the temperature should not be lower than 15 ° C. If the temperature rises above 20 ° C in winter, the flowering will not be as abundant. The air in the room should be fresh, but you need to ventilate carefully so as not to blow through the plant in a draft.
The indoor hoya plant at home requires abundant watering, starting in March and ending in October. You need to water it with settled soft water as soon as the topsoil dries up. Since November, watering is reduced, but not significantly - it is watered a couple of days after the topsoil dries up. It is advisable to water with lukewarm water. If watering is carried out rarely or stopped altogether, then some of the roots die off in the hoya and the plant begins the growing season.
Every spring and autumn, the hoya is immersed in water of 30-40-degree temperature for about half an hour, and the earthen lump itself must stay in the water for about two hours - such actions lead to an acceleration of the approach of flowering and contribute to the good growth of the plant.
The hoya flower is unpretentious to air humidity, but in spring and summer, the plant can be sprayed, but do this with caution so that drops do not fall on the flowers.
Every two to three weeks, the hoya plant can be fed with complex mineral fertilizers - they are fed only in spring and summer, the rest of the time, feeding is not needed.
Flowering will continue until autumn, if the plant is provided with a lot of light. Also, abundant lighting affects the accelerated appearance of flowers. After the flower buds have set, it is better not to move the plant, because this can lead to shedding of the buds. It is better to prop up brushes with flowers. Long shoots of hoya are cut off after flowering, and short flowering branches should be left. Also, you do not need to cut the flower stalks - they will have buds for the next year. The use of a support helps to keep the branches of the plant upright.
To obtain a branched hoya, you need to pinch the branches after 4 leaves appear on them.
Adult specimens are transplanted every three years, and young ones every year, because they grow much more intensively in larger pots. Grow well in slightly acidic or neutral soil, where the pH varies from 5.5 to 6.5. The hoya plant is unpretentious to the soil, but the best mixture for this plant is 2 parts of clay-sod land and one part of greenhouse and leafy land. Another good mixture for hoya is two parts of clay-sod land, one part of leaf and one part each of sand and peat. Hoya Bella - she is beautiful hoya - prefers a mixture of equal parts of humus, leafy earth, sand and peat, and add little charcoal. Be sure to provide good drainage for the hoye. The plant is great for hydroponic cultivation.
Hoya propagation in room conditions is carried out by cuttings throughout the growing season (best in spring or autumn). Cuttings can be of different lengths, but preferably with 1 or 2 pairs of leaves. You need to cut the stalk below the node, because the roots will not necessarily grow from the node - they can also grow between them. You can root in water or in a substrate of one part of sand and two parts of peat. It is desirable to maintain soil temperature at 20 ° C. Hoya cuttings should take root approximately at the end of the third week, after which they are planted in pots 9 cm in diameter with a mixture of earth from two parts of leafy soil, one part of sod land and sand, and half a part of humus earth with the addition of fertilizer.
If there is a desire to see flowers on a new plant in one year with the transplant, then hoya should be propagated with stem branches. On one of the shoots of the plant, a small incision is made, after which they cover the incision site with moss, wrap it with twine and wrap it with plastic wrap. After the roots appear, you need to cut off the upper part of the shoot and plant. To obtain dense bushes, 3-5 cuttings should be planted in one pot.
The smell of hoya flowers can cause headaches, and the leaves can cause dermatitis.
Hoya leaves turn pale. Leaves may turn pale, curl, or dry out at very low temperatures or too much light.
Hoya sheds leaves. Leaf fall can be caused by very hot and dry air.
Hoya sheds buds. Flower buds fall off with a lack of moisture or with excessive watering. This also happens when the air is too dry.
Hoya leaves fall. Shoots and leaves can crumble if drainage is poor or if water is too cold.
Hoya is rotting. Excessive watering along with poor drainage can cause root rot and the bottom of the stem.
Hoya drops flowers. Flowers fall off due to insufficient light, as well as if the plant is moved during the flowering period.
Hoya leaves curl. The leaves turn pale, and the growth of hoya is inhibited with a lack of nitrogen in the soil. To correct the situation, you need to feed the plant with urea 1 g per 1 liter.
Hoya leaves turn yellow and fall off. The leaves will turn yellow, wither and, as a result, fall off if the plant is flooded, or, conversely, if it is not watered enough. Another reason may be too low air temperature.
Hoya pests. Most often, the plant suffers from scale insects, aphids and whiteflies. Spider mites and mealybugs also feast on Hoya.
The main habitat is the peninsula. Malacca. This species is climbing shrubs with pubescent shoots. The leaves are oblong, oval in shape, up to 20 centimeters in length. Leaf blades are smooth, rounded at the base, shortly pointed at the apex, leathery. The pubescent petiole is up to 7 centimeters long. Flowers hang down with an umbrella of 7-10 pieces, up to 20 centimeters long, dark red inside and yellow-green outside; the crown is shortly pubescent with petals arranged in the form of an asterisk on pubescent short pedicels; smell very nice.
It lives in the Malaysian forests. The plant curls, has linear oblong leaves. It has numerous yellow umbrella-shaped flowers. Rounded tooth crown. The petals are narrow.
Or hoya motoskei (Noya motoskei). It lives in Australia and tropical subtropical zones of Asia, mainly on rocks and in forests. These are vines, reaching a length of 6 meters, with creeping pubescent stems. The leaves are ovoid; are oblong and heart-shaped; up to 8 centimeters in length and up to 4 in width; dark green; leaf petioles are short, and the leaves themselves are fleshy and shiny; leaf apex shortly pointed, but more often obtuse. Flowers are collected umbrella-shaped; white or pale flesh-colored, with a pink crown in the center. The flowers are kept on slightly pubescent pedicels, the length of which is up to 4 centimeters. The five-membered corolla, 1.5 cm in diameter, has a pleasant aroma. Corolla lobes densely pubescent from above, wide, and their edges are curled. Hoya fleshy blooms well during the growing season (from spring to late summer), is grown both in greenhouses and in rooms.
Grows in the forests of Burma. These are shrubs of small stature with creeping thin shoots, densely covered with leaves. Leaves are lanceolate, ovate, small, up to 2.5 centimeters long, dense, slightly convex, pointed at the top. Small flowers hang like umbrellas; 1.2-1.5 cm in diameter, white, waxy, divided into 5 lobes, with a purple-red crown. Blooms heavily throughout the summer. In warm rooms, it is often used as an ampelous plant. The beautiful hoya is a very ornamental plant.

Hoya is a succulent vine, it has firmly entered our life as an ornamental, unpretentious plant.
The native land of the plant is the tropical rain forests of Asia (from Nepal to Indonesia), Australia and Polynesia, Central and Southeast Africa, India, Madagascar, the Canary Islands, the Himalayan mountain ranges. Outwardly, the leaves and flowers of the hoya seem to be sculpted from wax, therefore, hoya is often also called wax ivy, and in America the plant is called "porcelain flower".
Ivy contains a large number of nutrients, due to which the plant is considered healing. It is used to make medicines that are used to treat liver diseases, as well as for coughs and pain during menstruation in women, and they also help strengthen the body's immune system. Ivy is also quite widespread in alternative medicine.
This plant has such beneficial properties as:
Liana helps to cleanse the air in the room from cigarette smoke, as well as from harmful substances released during the operation of the gas stove and when using detergents.
My grandmother's favorite plant was the fleshy hoya (Hoya carnosa), the popular name is wax ivy. This ivy grew and bloomed therefore. everywhere I know everything about caring for this beautiful and very unpretentious liana. It's time to share my knowledge with you.
Hoya carnosa is native to Asia and Australia. It has thick fleshy leaves and the same heavy stems, since this vine is a succulent. In an apartment, it can grow up to impressive sizes, up to 6 meters. Distinctive features - are covered with small specks of leaves. It blooms with unusual white flowers - "baskets" with a red core. flowers - These are weather forecasters. They accurately predict the approach of rain - they are covered with dewdrops. As a child, I often tasted them, as they were Turns out. sweet, it was impossible to do this, after all, the hoya is fleshy - a poisonous plant.
In general, waxy ivy care is simple and differs little from other succulents. Important conditions are rare (about 1 week at a time) watering, warmth and good light. But the features are the content that should be considered:
1. Hoya carnose can grow in the shade. But this bloom will affect her. Charming "baskets" will be formed, otherwise they are not rare at all. It is not necessary to keep this windowsill on the vine. It can be hung on the cornice, and set aside a little distance from the window. But the lighting should be bright! However, on the south side, wax ivy will need shading. On the windows of others, it is unnecessary to shade the orientations of the hoyu.
2. It is rarely necessary to transplant this plant. Only when the roots of the earthen lump are entwined.
3. Hoya dishes should not be large. The smaller the flowerpot, the better the.
4. The soil for this plant should be poor, as well as for other Hoya.
5. Fleshy succulents do not tolerate drafts. At all. She sheds leaves from them.
6. Faded flowers should not be cut off. Let it hang dry "place". New ones will appear on their baskets.
7. Fertilizing hoya is not often necessary. Enough once a month during the growing season for succulents.
8. Water the plant with settled soft water.
9. The enemy of the hoyu - If. scale insect notice its presence on the leaves, you should place the soil in the pest sticks.
10. Due to the heavy overgrown hoya, the stems may fall out of the pot. To prevent this from happening, she should be tied up or given more.
And the support is one observation. Once my father forgot his hoyka on the cold (but glazed) balcony, and there he kept her without watering until spring. The leaves of the plant have become larger and more succulent.
Hoya fleshy (hoya carnosa)
Hoya beautiful (hoya bella, Noya bella)
Flowers of this variety resemble arrows.
According to Feng Shui, hoya is considered a very family flower, it is advisable to place it in the bedroom - it harmonizes family relationships, restore relationships, enhance emotions and improve sex.
Insects harm the hoye, one of them is the scabbard, a soap solution helps well from this ailment
As a rule, the most difficult period for hoya, however, as well as for other plants, is autumn, at this moment there is a sharp drop in temperature, lighting and humidity, which is a problem for tropical plants. For home hoya, the difficulty is that the heating season begins, and the fumes that come from hot batteries always negatively affect green foliage. In hoya, climate change rejection is expressed in the yellowing of the leaves. What to do in this case?
But these are ways to solve the simplest of problems, but what to do when the plant is struck by a disease? A simple potato broth helps to cope with plant sores, it contains potassium, which makes the plant stronger, hardy, with good immunity.
Mold is an equally serious ailment. It appears for several reasons: either the plant was watered too often, or the water has an increased coefficient of hardness. But if everything is clear with the overflow, then with hard / soft water everything is more complicated. How to achieve water softening? Just settling water is not enough here. In order for the water to become softer, you can use this advice:
If it so happened that the earth itself has become moldy, then the upper, affected layer must be removed and poured fresh. If all the soil is affected, then a transplant is necessary, and the pot is disinfected with a solution of vinegar and water (1: 2)
Hoye and insects are also harmful, one of them is the scabbard, which sucks the juice, and therefore the vitality from the stems. In order to cope with the scabbard, you need to manually remove the insect, and then the plant is washed with soapy water and rinsed with warm water.
Chervens also do a lot of harm; they are removed with a cotton swab dipped in alcohol. After the hoya, it is washed with water.
Collecting exotic plants is a topic as constant as it is inexhaustible. I think I was not the only one who wondered why this or that representative of this vast kingdom at different times was in the center of attention of flower growers. Saintpaulias, orchids and cacti, ferns and fruit plants - each of these groups experienced a heyday and decline in popularity, but retained many fans around the world. And in the last decades of the last century, hoyi were among the most desirable plants for flower growers. What is the reason for this growth in popularity, what are the interesting hoyi and what types are available for amateurs today? In this article I will try to answer these and other questions, and also talk about the basic techniques of agricultural technology.
Rod Hoya (Hoya) refers to family Lastovnievye (Asclepiadaceae), which was first described by botanist Robert Brown in 1810. A distinctive feature of the plants of this family are special gelatinous formations - pollinas, which contain their pollen. Among other higher plants, such formations are known only in orchids.
The closest relatives of the hoy family are such well-known indoor plants as dyschidia - a liana very close to the hoy, but smaller in size, stephanotis - a tree-like liana with unusually beautiful and fragrant flowers, asclepias - a herbaceous shrub with bright flowers of various colors, as well as succulent echidopsis, stapelia, trichocaulon, ceropegia and several other genera. As you can see from this list, many members of the family have spectacular and beautiful flowers, while others have unusual stems or leaves. About hoyi, we can say that they are equally endowed with both.
In natural conditions, hoyi are common on the islands of the Malay Archipelago, partly in India and tropical Australia. According to the type of growth, they are divided into climbing, creeping species and shrubs. According to various sources, about 200 species are united in the genus, but their taxonomy has not yet been worked out.
Strange as it may seem, but for many years scant information about only two types of hoi migrated from book to book, and one might get the impression that this is the end of the diversity of existing species. However, if we talk about accessibility, then it was so. In one of the most authoritative publications, Saakov's book "Greenhouse and indoor plants and their care" in 1985, 4 species are mentioned, and this is a publication of the botanical garden of the Academy of Sciences ... lovely (Hoya carnosa and Hoya bella), in fact, their variety is much wider. Today, thanks to the opportunity to receive new items from foreign nurseries, lovers of rarities were able to appreciate the beauty of these beautiful plants in all their diversity.
Flowers are undoubtedly the main, but not the only dignity of the hoi. Their color, as a rule, is dominated by white, pink or red tones, but species with bright yellow, orange, green and brown colors are not rare. The shape of the inflorescence in most species resembles an umbrella, in which from 5 to 20 small, star-like flowers are collected. However, among the hoi there are species that have only one flower per inflorescence, for example, Hoya pauciflora. And the record holder among them - with the most numerous inflorescence - is considered Hoya macgregorii - its flowers can number up to 150 (!) Flowers (now this species is considered a variety Hoya incrassate). The size of individual flowers in an inflorescence can vary from 3-4 millimeters in Hoya bilobata up to 6-8 centimeters in the most large-flowered - Hoya onychoides and Hoya imberialis... However, hoi flowers differ not only in size and quantity. The main feature that is the basis for their classification by Dr. Schlechter is the shape of the flower.
In accordance with this classification, 7 groups are distinguished:
Otostemma - have small flowers with strongly curled back petals, common in coastal regions of Malaysia and New Guinea. Typical view - Hoya lacunosa.
Hoya (or Eu-Hoya) - this is the most numerous group, there are more than 100 species, it combines typical hoyi with pubescent flowers of medium size, a typical species Hoya carnosa (one of the representatives of this group Hoya davidcumingii).
Plocostemma - an intermediate group between Eu-Hoya and Pterostelma, which includes species - the owners of the most beautiful flowers among the hoi. A characteristic feature of the structure of their large flowers are vertically arranged dense petals, which are strongly bent back. Distributed in the mountainous regions of the Malay Archipelago, a typical representative Hoya lasiantha.
Pterostelma - combines views from the complex Hoya australiswith star-shaped flowers of medium size with wide petals. Typical views - Hoya acuminata and Hoya albiflora.
Oreostemma - contains only one view Hoya oreostemma, since according to the structure of flowers, it cannot be attributed to any other group. It has large inner crown petals and fleshy cylindrical outer petals strongly bent back.
Physostelma - combines very beautiful species with bell-shaped flowers, which can be quite large. Typical view - Hoya campanulata.
Eriostemma - species from this group are so different from other hoi that for a long time they were isolated into a separate genus. The final unification was made only in 2001 on the basis of the latest research. Their main difference from other groups is the structure of the flower tube and the shape of the petals of the inner crown, the flowers are located on a short and thick peduncle, they emit a lot of nectar.
A wonderful property of hoi flowers is that many of them have a scent. This trait is highly prized in indoor floriculture, but few plants possess it. From the species that have already bloomed in my collection, I remember the pleasant aroma Hoya australis, Hoya lacunosa, Hoya parasitica, Hoya serpens, their flowers can combine various floral and fruity shades, often with dominant aromas of vanilla and citrus. Often, the odor spread by flowers is so strong that even one blossoming inflorescence can “perfume” the whole apartment like a gardenia or jasmine. Such are, for example, Hoya lacunosa and Hoya parasitica, the rest of the species, as a rule, have a slight odor, which is clearly distinguishable only near the bush.
The ability to bloom in all hoi is the higher, the older the plant, however, even the youngest specimens, which have already bloomed once, are able to form new flowers on the same peduncles. At the same time, the flower shoot grows in length in the same way as a normal vegetative one. For example, Hoya macgregorii last year it blossomed on one peduncle seven (!) times, and several times formed new flowers on eight peduncles at the same time.
Each type of hoi is characterized by flowering only at certain times of the year. There are species that bloom their flowers with the arrival of the autumn cold (Hoya retusa, Hoya thomsoni), others, on the contrary, at this time only rest and lay buds, which will open under the first rays of the spring sun (Hoya serpens, Hoya longifolia, Hoya parasitica).
Still, most hoi bloom their fragrant flowers in late spring and summer, when they can get enough sunshine in our strip.
The duration of flowering hoi can be from one to two days to several weeks, but these plants never completely lose their leaves. The beauty of their foliage is by no means the last reason why hoyis are gaining more and more popularity.
Here is just a small list of the variety of shapes and structures of hoi leaves:
