This amazing plant does not need flowers at all, because nature has painted its velvety-sticky leaves so brightly and variedly that you can organize a very beautiful flower bed from some Coleus of different varieties. That is what many gardeners do today. And people involved in landscaping city streets, alleys, parks and gardens are very actively using the plant to make cities look smart and cheerful. The plant is unpretentious, willingly helps any novice grower to achieve good results
Variegated sticky leaves
The genus Coleus or Nettle has more than 150 species of perennial plants with decorative leaves, which are grown outdoors as annuals in areas with cold winters. The plant is called "nettle" for the similarity of its leaves to the leaves of our home-grown nettle.
Plant species
•
Coleus Bluma (Coleus blumei) is the most common plant species with many garden forms. Its large, broadly oval leaves are arranged oppositely on tetrahedral erect stems. The surface of the leaves is velvety and bright. All the colors and shades of the heavenly rainbow were adopted in the coloring of the leaves. Here there are white, and yellow, and orange, and green, and red, and brown colors. Sometimes the surface is replete with several shades, drawing patterns on the leaves, or the leaf has a green or golden-yellow border around the edge. But the flowering is inferior in its beauty to the leaves, representing a racemose inconspicuous inflorescence of small, white or blue, two-lipped flowers.
•
Coleus Frederica (Coleus frederici) - this species stands out from the general row of Coleus, because it is famous not for leaves, but for purple-blue flowers, collected in small brushes. The leaves are colored dark green and have a crenate edge (with rounded, relatively wide teeth).
•
Coleus pyramidal-paniculate (Coleus thyrsoideus) - This species also attracts more flowers than leaves. Its leaves are heart-shaped with a jagged edge of the familiar green color. Apical long inflorescences, collected from tubular blue flowers, bloom in winter. That is, this species is not for areas with frost, perhaps only as a houseplant.
•
Coleus Vershaffelt (Coleus verschaffeltii) - has velvety purple-red large leaves with a green border.
•
Coleus "Underwater" (Coleus "Under the Sea") - a new series, developed by Canadian students, amazes with fantastic shapes and colors, unpretentiousness to living conditions, resistance to air temperatures. They can grow in sun and shade. But I don’t know if we sell such seeds. But, looking back at the experience of students, each florist can start breeding himself and bring out a new, unusual and beautiful variety.
Growing
Indoor coleuses love lit places. And in the open field it is better to plant them in partial shade so that the brightness of their colorful leaves does not fade.
The soils are preferably fertile, light, well-drained.
Plants are hygrophilous and require frequent and abundant watering in summer. The water should not be cold.
To obtain a plant with thicker foliage, the tops of the shoots are usually pinched. Flower buds in species with multi-colored leaves are removed, since they do not add decorativeness to the plant, and they take away the strength of the plant.
Propagated by seeds, sowing in January-February. Less commonly propagated by cuttings, which can be done throughout the summer. Particularly valuable species are usually cut in March-April.
Usage
Thanks to its colorful, elegant leaves, Coleus is considered one of the attractive plants for our homes. He brings joy and the triumph of the colors of life into the house. By choosing different varieties, you can harmoniously complement the interior of the room in the desired color scheme.
As an unpretentious annual, it is in demand in summer cottages as a border for flower beds, flower beds and garden paths. It may well become an independent decoration of a green lawn. Beautiful flower beds, made up of different varieties of plants, differing in color of the leaves.
Diseases and pests
They are attacked by spider mites, thrips and voracious aphids. Conventional pest control.
