Osteospermum - African "chamomile"
Osteospermum ("Gazania" or "Gazania") is a small and very beautiful plant native to South Africa. It looks like a chamomile. Gatsania is a perennial plant, but in countries with cold climates it can be perennial or annual.
Short description
Like any southern plant that grows in a warm and arid climate, osteospermum has a strong taproot and a relatively small stem, which may even be absent. Massive green leaves of a dark or grayish hue on the reverse side have a silvery pubescence, which is necessary to retain moisture and reduce the evaporation of liquid.
Osteospermum is grown in large vases or pots and is used to decorate balconies, terraces or loggias. Often grown in gardens or flower beds, it goes well with gray stones if planted near garden paths. In addition, the flower remains fresh for a long time (about 8-9 days), so it is great for making bouquets.
The double inflorescence of gazania has a size of 3 to 8 cm in diameter and is a barren tubular flower in the middle (usually blue or blue), surrounded by reed flowers at the edges (the most varied colors are possible, from white to purple).
The life time of each inflorescence does not exceed 5 days, however, new buds constantly grow in its place. Thanks to this, the plant has a long and constant flowering, which, under favorable conditions, can bloom until mid-October. Bright inflorescences of gazania open on a sunny day and close at night, protecting the flower from night humidity.
Species and varieties
Gatzania is a very versatile plant. At the time when it was first brought from South Africa, such a wide range of varieties did not yet exist. However, for a long time the flower was subjected to the experiments of breeders, as a result of which now even the most sophisticated plant breeder can choose the right variety for his garden. Special admirers can pay attention to terry types. Requiring certain skills in care, they compensate for the difficulties in breeding with their unique appearance.
"Eklon"
One of the most famous varieties of gazania. It has a dense stem, grows profusely. It loves warmth and does not tolerate cold climates. Breeders brought out of it a large number of hybrid varieties that differ in color and shape. The most famous of them:
- "Buttermill";
- "Congo";
- "Zulu";
- "Volta";
- "Silver";
- "Sparkler";
- "Sky and Ice";
- "Bamba";
- "Cream Symphony".
Ampelny
Plants of this variety have a large bush containing a large number of flowers. Does not tolerate cold very well.In order to leave it as a perennial plant, it is necessary to place it in a cool, but bright room, and occasionally water it.
"Cool"
It tolerates low temperatures well, has the longest flowering. It also tolerates heat and wind. Along with this, it has the only drawback: due to the peculiarities of selection, it is an exclusively annual plant.
"Mix"
In most cases, it is grown as an annual plant, although it can be perennial. Prefers a lot of sunlight, but it can be grown in the shade. It tolerates both cold and heat well. In order to grow it as a perennial plant, it is necessary to place it in a bright, cool room in winter and water it occasionally.
"Ballad"
It tolerates very well not only cold, but also heat. Large inflorescences retain their beauty in all weather conditions, withstanding temperatures down to -5C. The variety has a long flowering, which can last until mid-autumn. Suitable for growing in the shade.
"Nice"
A perennial flower, loves a warm climate, while enduring winter well. The variety has several varieties:
- "Lady Leitrim";
- "Buttermilk";
- "Sparkler".
"Harsh"
It stands out clearly from the background of other varieties. It is often used as an annual, although it is also suitable for perennial cultivation. This undersized variety grows no more than 30 cm in height. The leaves are dark green in color. Inflorescences are red, orange or yellow.
Hybrid
A hybrid variety discovered as a result of selection. Grown as an annual plant. It has large flowers that reach 8 cm in diameter.A feature of the variety is reproduction, which is carried out exclusively by cuttings.
Linear
This variety is characterized by increased tolerance to drought and frost. This allows you to plant seedlings in the ground already in the first half of April. This variety loves moist and loose soil.
Visually, this variety is distinguished by a rather spectacular form of leaves and a large diameter of flowers.
Colors
The color scheme of gazania is very diverse and depends on the particular variety. Osteospermum 'Eklon' petals can be pink (Volta), purple (Bambe and Congo), yellow (Buttermilk, Zulu and Cream Symphony) or white (Silver Sparkler, Sky and ice).
Osteospermum ampelous differ in pink-white color of the leaves. Variety "Coolness" has snow-white petals and a blue-violet tubular middle.
reproduction
Most varieties of gazania are successfully propagated by seeds. To collect the seeds, you need to wait for the seed pods to ripen. Unlike other flowers, osteosperm seeds are not located in the middle, but on the petals. Particularly good seeds can be collected from plants that have started flowering early.
cuttings
However, some varieties of gazania, bred by breeding, do not produce seeds at all. Therefore, they must be propagated by cuttings. Cuttings must be harvested in autumn or spring, cutting them with a sharp knife. The recommended cutting length is 5-7 cm.
Then you should cut off the lower leaves, and then place the cuttings in a container with a substrate.
You should also remember about the thermophilicity of the plant: the cuttings should stand in a warm place with good lighting. It will not be superfluous to cover them with polyethylene or glass, but do not forget to ventilate.In a little more than a week it will become clear which specimens have taken root.
How to choose seeds?
In order to choose seeds, you just need to decide on the variety. Thanks to selective breeding, today there are a huge number of varieties, each of which has certain characteristics. When choosing seeds, it is necessary to take into account the characteristics of a particular variety, personal preferences, as well as the purpose of cultivation.
Before you start planting seeds, you must first understand their properties. Seeds that have been stored for more than two years are not suitable for growing gazania. The result in this case, most likely, will be unsuccessful. Even those seeds that were collected a year ago will give a much greater likelihood of germination.
You also need to remember that planting seeds directly into the ground is possible only in regions with a warm climate, while in others you must first germinate the seeds and grow seedlings from them.
Growing, planting and care
To get seedlings, it is necessary to sow germinated seeds in boxes with a substrate (from February to April). Soaking seeds is not recommended as the plant does not like moisture.
Sowing for seedlings
It is necessary to choose the time of sowing seeds depending on the region and its climatic conditions. If the spring is cold and comes late, then you should not plant the seeds too early, as in this case, additional lighting will be required for the growth of the seedlings. However, if you plant gazania late, then flowering will have to wait much longer.
In this way, the earliest time for planting seeds is mid-March.
Gatsania must be planted in deep boxes so that nothing interferes with the growth of its long root.It is necessary to sow seeds at a fairly large distance (2-3 cm) and it is advisable to do this in a checkerboard pattern. You can fill them a little with soil on top and cover with a film. The room temperature should be around 18-20C.
At room temperature, after 7-14 days shoots will appear. Even after the same amount of time, the seedlings must dive. The plant should be planted in a flower garden in mid-May. Osteospermum loves sunlight, so the use of artificial lighting can greatly speed up flowering.
seedling care
You need to care for seedlings in this way:
- Place the seedlings in a cool place with good lighting.
- Water regularly, but do not flood.
- When leaves begin to appear, seedlings should be planted in different containers.
- To pull the plants was not so intense, you can use clothespins.
- Hardening of seedlings should begin in May.
If the container in which the seedlings are grown is deep enough, then it is not necessary to dive (replant) them. However, if the depth of the box is small, then after the appearance of the first leaves, it is necessary to transplant the seedlings into pots. After that, the seedlings should be transferred to a place with a cooler temperature. At the same time, you can start hardening seedlings by opening the window for a short period of time.
In regions with hotter climatic conditions, seeds are planted in March or April immediately in the soil and cold greenhouses.
How to properly harden?
Hardening is necessary to carry out in order to gradually accustom the seedlings to external conditions before they are directly planted in the ground.
Hardening should begin with a short exposure to fresh air, 2-3 hours will be enough.Gradually, you need to increase this time so that at the end of hardening, the plants can already be in the fresh air all the time. It is also gradually necessary to gradually accustom the seedlings to sunlight, increasing the time spent by the plants in the sun every day.
In the event that the weather is still cold outside, you first need to open the window during the day, for a short time (1-2 hours is enough for a start), and be sure to close it at night. After a few days, the window can be left open also at night.
Hardened gazania will tolerate temperature changes much better, bloom faster, and the flowering itself will be longer.
Outdoor cultivation
Osteospermum is a flower that can be planted in two different ways.
One way is to plant gazania in flowerpots. A plant planted in this way will delight with its flowering for several years, because after the onset of cold weather, flowerpots will be very easy to transfer to the room.
Another option is to plant seedlings in open ground. It must be remembered that gazania does not tolerate wet soil, preferring rocky or sandy soil.
It must be remembered that almost all varieties of osteospermum love sunlight, so you need to choose the appropriate place for planting.
Seedlings are transplanted into open ground along with pots. In the case where the seedlings were grown in a box, you need to use a long scoop to transplant each flower without damaging its roots. Landing in this case is carried out together with a clod of earth. Plants are planted so that their bushes are not less than 20 cm apart.
Gatsania should be planted in loose and fertile soil.It is desirable to fertilize the earth. The soil should not be waterlogged.
Growing at home
Gatzania can be grown in a pot. In this case, the diameter of the pot should not be less than 15 cm. It is advisable to make drainage using a mixture of sand and peat placed on the bottom (a layer of about 5 cm).
Summer Care
The main points of caring for osteospermum in the summer are watering, fertilizing, loosening, mulching and removing faded buds.
We must not forget that this South African plant is much more resistant to drought than to excessive moisture. Excessive watering of gazania can provoke rotting of the roots and, as a result, the death of the plant.
To prolong the flowering time, both organic and mineral fertilizers can be used. The first time you can fertilize the plant immediately after transplantation, and then - once every two weeks. It is necessary to regularly loosen the topsoil, while removing weeds. To improve the structure of the soil, you can use humus or sawdust.
How to mulch?
Mulching the soil is essential to prevent weeds from appearing, as well as to improve the supply of moisture to the roots and thereby avoid unnecessary watering. The bottom line is to cover the ground around the plant with a dense layer of mulch. This layer prevents weeds from germinating and also retains moisture.
To mulch the soil, you can use film, cardboard, or wet paper. With these materials, it is necessary to surround the earth around the plants, sprinkling them on top of the earth, but it is better to use more suitable materials of natural origin for this:
- peat;
- humus;
- sawdust;
- needles;
- straw;
- cut grass;
- leaves;
- tree bark.
If grass clippings are used as mulch, be aware that they can attract the attention of snails and slugs to the plant. It is especially good to perform mulching using thin twigs and cones. To do this, they must first be crushed with a garden shredder.
A few words about fertilizers
Top dressing with fertilizers is carried out once every 1-2 weeks. In this case, you need to ensure that the solution with fertilizers gets under the root of the plant. In the event that fertilizers get on the leaves, it is necessary to wash them off with clean water.
In order not to produce weekly processing, you can use slow-acting fertilizers.
Winter Care
Osteospermum is resistant to short-term frosts. Having survived them, the plant continues a full life. In order to keep the gazania in winter, you need to transplant it into flowerpots. This must be done before the onset of autumn cold weather. For the winter, you need to place the plant in a cool room, while the temperature should not fall below -10C.
As soon as warm weather returns, gazania can be transplanted into the ground again. In order not to damage the roots, you can grow ostiospermum directly in a flowerpot in which the plant will feel good, regardless of the time of year.
Diseases and pests
Osteospermum is almost not susceptible to diseases, however excess moisture can lead to gray rot, the appearance of which is evidenced by brown spots on the leaves, covered after some time with a gray coating.
To prevent the spread of rot, the infected flower should be removed, and healthy plants should be treated with one of the following drugs:
- phytosporin;
- Bordeaux liquid;
- topaz;
- champion;
- integral.
Other dangers that threaten gazania are aphids, snails and spider mites. It is necessary to inspect the bushes from time to time. If small holes appear on the leaves, and they themselves turn yellow, this is a sign of a spider mite. Bushes infected with it do not have to be removed: they can still be cured. You just need to cut off the affected leaves and treat the plant with phytoverm, then closing it with a plastic bag.
You can save a flower from aphids by treating it with a solution of soapy water. You can also use fitoverm for this. Processing should be done in dry weather, when there is no wind, and preferably in the evening, when it is already dark.
Prevention
To prevent the appearance of diseases and pests, you should regularly inspect the plants. It is especially important not to overmoisten the gazania with abundant watering. However, plant diseases are not necessarily the result of improper care.
If gazania grows outdoors, then you need to be prepared for the consequences of heavy rains. In order to protect the plant from waterlogging, it is enough to plant it where water will not accumulate, forming puddles.
Application in landscape design
The reason why these plants are used to decorate the garden is because of the large flowers, which also stand out in contrasting colors. A variety of textures and colors allows you to apply osteospermum in a variety of ways.
- Low-growing varieties of osteospermum are well suited for decorating alpine slides. But in all its fullness, gazania reveals its appearance as part of flower arrangements. Gatsania goes well with ursinia, lubelia, dimorphoteka and arctotis.
- The small height of osteospermum bushes makes its use appropriate. as track design. With the help of gazania, you can delimit various garden areas, thus creating borders.
- With its bright colors, osteospermum can bring variety to the flower beds. To do this, you can combine different varieties of gazania, or plant gazania along with other flowers, which should be combined with osteospermum in height.
- Another option - creating various patterns, which will turn out if the gazania alternates with other plants that have voluminous green foliage, which is distinguished by unusual shades. You can thus create various patterns, circular, wavy, and possibly even in the form of any animals or insects.
- Gatsania covers the soil well, so you can use it to mask ugly plots of land. Dense leaves of gatsania well hide black areas of the earth.
The short stature of the osteospermum makes it inappropriate to use it in combination with tall plants. Also, this should not be done because of the shadow they can cast on the gazing. It is preferable to use gazania in combination with plants of the same height.
Gatsania in a flowerpot goes well with lush green leaves of different shades.
Gatsania looks good next to other undersized plants.
Gatzania can be grown in hanging flower baskets.
