Coleus flowers. Spring protection of garden plants from pests and diseases

Coleus has been grown for centuries for its variegated leaves. This is a perennial unpretentious plant of the Lamiaceae family. The height of coleus reaches 35-70 cm. The genus includes about 150 species of annual and perennial herbaceous tropical plants. The most common is Coleus Blume, which is native to the island of Java. There are about 200 hundred hybrids and varieties of this plant, the leaves of which are colored very differently. It is believed that Coleus Verschaffelta has the largest and most colorful leaves. Smallest sizes has dwarf coleus.

The name of the genus Lamiaceae is derived from the Greek. the word koleos means “case”, since the stamen filaments of plants of this group grow together into a tube, covering the base of the pistil.

The painted leaves of coleus with jagged edges resemble those of croton, a more exotic and expensive plant. Due to this similarity and relative cheapness in the UK, coleus is called "the poor man's croton." In Russia, coleus received a different name - "nettle". since its leaves are somewhat reminiscent of nettle leaves.

Coleus is usually grown as annual plant. Its leaves do not lose their decorative quality throughout the year. To enhance bushiness, it is recommended to pinch the apical shoots of coleus.

TO temperature Coleus is not very demanding. In summer it can be within 16-25º C. Make sure that in winter the temperature does not fall below 12º C.

Lighting should be bright, since coleus is a light-loving plant. A simple rule applies here: The less pure green color its leaves have, the more light the plant needs for normal development! But at the same time, coleus needs shading from the bright midday sun. In summer, a pot with a plant can be placed on a balcony or open veranda.

Watering Coleus should be regular. In summer it is abundant, and in winter it is moderate. For watering, use soft water at room temperature.

Air humidity- high. Coleus leaves must be regularly sprayed with settled soft water at room temperature; spray more often in summer, and sometimes in winter.

The soil For coleus, slightly acidic or neutral is suitable. Take a mixture of turf and deciduous soil, humus, sand and peat in a ratio of 4:4:2:1:1.

Feeding produced in spring-summer period during intensive growth, once a week with mineral or organic fertilizers.

Transplanted overgrown plants every 2-3 years. If coleus are grown as annuals, they do not need to be replanted.

Reproduces Coleus by seeds or rooting cuttings. Seeds are sown in April - May, 5-7 pieces in holes located at a distance of 3-5 cm from each other and sprinkled with a thin layer of sand. Stem cuttings They take root easily in wet sand, and they sprout roots just as easily in water.

Bloom coleus is modest and not its most striking feature. Flowering begins late spring or in summer. The flowers are small with a bluish tint, collected in a spike-shaped inflorescence. Usually the flowers are removed; this procedure makes the plant more luxuriant.
