Iberis, or Iberian (Iberis), is an annual or perennial garden flower belonging to the genus of herbaceous plants from the Cabbage family. Domestic florists this plant grown in open ground is also known under such names as pepperbox, variegated petal and stennik.
The flowering of ornamental grasses or shrubs is represented by umbrella-shaped racemose inflorescences. Decorative garden flowers are represented by several types and varieties, the cultivation of which does not cause difficulties.
Evergreen (I.sempervirens) is a perennial semi-shrub plant with a height of the aerial part of 30-40 cm and an oblong, whole-edge, glossy, dark green foliage. Umbrella inflorescences, up to 50 mm in diameter, are white in color. The most popular varieties include Miniature Flock, Findall, Snowflake and "Dana".
Umbrella (I.umbellata) is a flowering annual with an aerial part height of not more than 30 cm. It is characterized by bare, well-branched shoots and early flowering of dense umbrella inflorescences. The most popular were hyacinth-flowering varieties of the type "Gems" and "Express", and Blackberry Meringues, Fairy Mixed, Pomegranate Ice and Red Nash.
Gorky (I.amara) is an annual plant with a height of the aerial part of not more than 30 cm. It is molded by the presence of branched and well-pubescent stems growing from the root neck. The foliage is back-lanceolate, with serrated edges, of the next arrangement. White flowers with a lilac hue, collected in racemose inflorescences. The most popular varieties in home gardening "Tom Thumb", "Hyacintenblutig Riesen" and "Weiss Riesen."
Rocky (I.saxatilis) in vivo grows in rocky areas in southern Europe from the Iberian Peninsula to the Black Sea coast. This evergreen highly decorative shrub has an aerial part with a height of not more than 10-15 cm and forms a characteristic thick rounded curtain.
Crimean (I.simplex) is a small perennial flowering herbaceous plant with an aerial part no more than 5-10 cm high and pubescent grayish-green foliage. The flowers at the bud stage are purple but in dissolution they acquire a characteristic snow-white color.
Gibraltar (I.gibraltarica) hails from southern Spain and Morocco. Gibraltar is characterized as a highly decorative semi-evergreen species, forming a huge number of small pinkish flowers. The height of the aerial part does not exceed a quarter meter with a diameter of 40 cm. The most popular varieties are Gibraltar Canditaft and "Chameleon".
Planting seeds is a great way to get a perennial shrub plant or herbaceous ornamental annual. Experienced flower growers recommend sowing seeds directly into open flower beds around mid-April. The standard embedment depth of the seed can vary between 7-10 cm.
Too deep sowing causes difficulties in the emergence of seedlings and a decrease in germination. Under favorable soil and climatic conditions, the first shoots appear after about seven days. Also sowing in the winter gives a very good result.. In this case, active flowering is observed in May or the first decade of June.
Seedling is a little less common way of growing decorative culture. This method is not very popular, which is caused by the fragility of the root system. Seedlings are very difficult to tolerate the transplanting process, they are often sick or inhibited in growth and development, therefore it is recommended to plant the seeds immediately in peat pots.
The plant needs regular care, including the proper organization of irrigation activities and compliance with the feeding regimen. It is also necessary to systematically remove all weeds, shovel loosely and periodically carry out inspections in order to timely detect damage by diseases or pests.
Perennial or annual grows beautifully and blooms profusely when planted in areas well-lit by sunlight, but the sunliness of this ornamental plant is quite relative. Iberis can easily tolerate some shading., therefore, with this culture you can make rockeries and alpine slides not in the sunniest places.
For full growth and development, as well as long-term flowering, the areas represented by loams are best suited, but the lighter and looser the soil, the more convenient it will be to care for the crop. Too dense or excessively dry soils should not be allowed for cultivation.
Sowing seeds in individual seedling pots or specially prepared boxes is necessary from March to the last decade of April. For growing seedlings, you can use any soil mixture for decorative flowering plants. Seeds should not be deeply buried. The temperature regime before germination should be approximately 18-22aboutC. After the emergence of mass shoots and the formation of several real leaves on them, it is necessary to thin out the seedlings. Seedling material transfers the dive procedure quite heavily.
On open-air flower beds, seedlings should be replanted around mid-May, providing, if necessary, a frame-film shelter. The standard distance between the planted seedlings should be at least 15-20 cm. Sowing seeds directly in open ground can be performed starting in mid-April, or traditional winter winter sowing can be carried out.
Irrigation measures are necessary for the plant exclusively in a very hot and arid period. The soil during irrigation should be soaked with water to the maximum depth, avoiding stagnation of moisture near the root system of plants. Too rare watering does not adversely affect the decorative annual or perennial culture.
The amount and composition of top dressing may vary depending on the type and quality of soil in the area. On too depleted soils or soils with insufficient nutritional indicators, standard complex fertilizers are applied only a couple of times a year. It can be used in spring and summer with nitrophosic top dressing. The introduction of organic matter by adding or mulching the soil around the plants with compost gives a very good result.
Equally important is an event such as cropping. This procedure allows you to get the most plentiful and long flowering. All flowering shoots should be regularly removed. The main pruning is carried out immediately after flowering. During this period, the aerial part of the perennial should be shortened by about a third.
After flowering, annual varieties must be completely removed together with the root system from the soil. Perennial partially cropped. Seeds gather after complete withering of inflorescences. Fruits should be cut as much as possible and laid out in a warm room, where the ripening process is carried out.
Seed boxes need to be carefully turned over regularly, which will ensure uniform drying. Well-dried Iberis seed material should be stored neatly packed in paper or cloth bags in a dry and relatively cool room. This method allows you to keep germination at a high level.
Iberis belong to the category of rather frost-resistant ornamental garden plants, but are able to freeze out in snowless and harsh winters. Among other things, perennials react very poorly to sudden temperature changes and the change of severe frost with a thaw. To provide a beautiful flowering garden culture with a comfortable winter, it is necessary even in the middle lane of our country to use shelter from the last decade of autumn. Good protection from frost can be fallen foliage, spruce spruce branches or ordinary dry brushwood with small layers of straw and hay.
It should be noted that umbellate and bitter species belong to the category of grassy annuals, and shrub perennials are represented by hybrid, evergreen, Crimean and rocky species.
The botanical and species features of Iberis allow amateur gardeners to use this decorative popular culture when designing alpine slides, as well as on rocky paths. Among other things, some varieties are just perfect for container growing. In this case, gazebos and terraces can be decorated with hanging flowerpots with Iberis.
It is undesirable to combine decorative culture with groundcover perennials. Very beautiful and original floral arrangements can be obtained when combined with phlox, tulips and muscars, as well as with the addition of different bells, yarrow and bluehead.
Domestic amateur gardeners have long and with great success used both annual and perennial Iberis in the design of personal gardens. This unpretentious and very resistant to adverse weather conditions decorative plant easily propagates even by self-sowing and does not cause any problems for gardeners.
