Few people in our country know what it is, since it is rare to find it in stores or at home.

Description of the genus

Under the name "osmanthus" a whole genus of deciduous evergreens is combined. All of them belong to the Maslinov family. The homeland of the plant is tropical forests from Asia to the Caucasus itself. Osmanthus is not yet as popular and widespread in Russia as, for example, in China. It has been grown there for more than one millennium, and not only as an ornamental, but also as medicinal plant. Osmanthus is associated with many legends and beliefs; it is traditionally considered a symbol of love and fidelity. Plants of this genus are shrubs or trees that have hard, dark green leaves with smooth or serrated edges. Osmanthus flowers can be snow-white or yellow in color, they exude a strong aroma, which is sometimes compared to the smell of magnolia and jasmine.

Osmanthus fragrant

Very often it can be found under the name of tea or fragrant olive. The homeland of the plant is Southern Japan, the Himalayas and China. AT vivo It is a tree or shrub up to three meters high. Flowers can be white or yellow, depending on the variety, have a pronounced sweetish aroma. Fragrant osmanthus - very showy plant with leathery leaves that have serrated edges. In nature, it begins to bloom in September, and this continues until spring.

Osmanthus grows quite slowly, but it is unpretentious and drought-resistant. It will grow in almost any soil. AT open field in our climatic conditions osmanthus will not take root, as it cannot withstand a long drop in temperature below zero. But he will feel quite comfortable in room conditions. If you want to grow a tree, then and in this case, osmanthus is perfect (photo below).

Which soil to choose

The osmanthus plant is not capricious, but nevertheless, for the best growth and development, some nuances must be taken into account. It is better to choose a place in the apartment with bright lighting, for example, on the south window, and in spring and summer, take it out to the loggia, balcony or terrace. It is best to choose a soil with a slightly acidic or neutral environment. The ideal ratio is 2:1 (fertile light soil and peat). You definitely need good drainage, so you need to put expanded clay on the bottom of the pot, and add coarse river sand to the soil. The plant does not require pruning, as this will reduce its flowering.

Propagation by seeds and cuttings

The first method is very long, since seedlings will have to wait at least six months, or even more. In addition, it all depends directly on the freshness of the seeds. If they are old, then it is necessary to carry out stratification so that the osmanthus is healthy and strong. What it is, every grower knows - keeping seeds at certain temperatures for their best germination (for osmanthus - three months in warmth and the same in cold). It is very easy to propagate the plant with semi-lignified cuttings. They need to be cut in July. Then dry the cut for several hours, dip it in a growth stimulator and root it in a mixture of peat and sand. When the roots appear, it is necessary to plant young osmanthus in separate pots.

Watering and transplanting

Watering during the period of intensive growth (in winter) should be plentiful, the rest of the time - moderate, water stagnation in the soil should not be allowed, but the land should not be overdried. Osmanthus is very fond of wet air, so daily spraying will only benefit him. Sometimes you can arrange a tropical rain for the plant in the shower, and the leaves should be wiped with a damp cloth from accumulating dust. Once a month during the growing season, osmanthus should be watered with a complex mineral or organic fertilizer.

Replant the plant only as needed. Osmanthus prefers to grow in a tight pot until the roots fill it completely. Young plants should be transplanted as they grow, while for large plants it will be enough to change only upper layer soil.
