family Begoniaceae.Rod begonia.
There are about 1,000 species of begonias various forms - shrubs, climbs shrubs, herbaceous plants with erect, climb or hang-downing shoots.The flowers of different sizes, many species can be considered in the first place Dekorativnolistvennye.
natural climatic conditions: the tropics and subtropics.
dekorativnotsvetuschie most common types:
Begonia * Hybrid hang-downing.Tuberous herbaceous plant with long drooping shoots.The leaves can be hairy and naked, light and dark green.Flowers large, double, of various colors (white, yellow, red, etc.).
Begonia borgtsevikolistnaya ♦ Large herb (up to 60 cm) with creeping stems, large palmate-dissected leaves (which allows us to consider it as Dekorativnolistvennye species), reaching a length of 50 cm Leaf Color decorative:. Green with olive or brownishshade and silver stripes along the veins.The flowers are collected in a loose brush on a long (60 cm) peduncle, small, whitish-pink.

Sorts "Altrinhem Pink" - flowers are bright pink, small, numerous, collected in the brush but 3-5 pieces, an increase of about 25 cm;"Rosa media" - pink flowers, small, often single, an increase of about 12 cm;"Rosa Erfordi" - flowers carmine-pink;"Foyerkugel" - leaves and flowers of red, various shades;"Shgarme" - carmine flowers or karmishyu red, green leaves.
Begonia slim ♦ Low-growing, herbaceous forms.The leaves are larger than the previous species (up to 8 cm).The flowers are small.
Varieties: "Weisse Perle" - white flowers, green leaves;"Carmen Nana" - flowers pink-red, reddish or bronze leaves with a red tint;"Nidrige Indianerin" - flowers densely lososinovye, red-bronze leaves.
Race Elatior Rieger includes krupnotsvegkovye varieties known from the beginning of the XX century Elatior groups, which differ as increased resistance to fungal diseases.They are characterized by very severe short-day (9 hours of daylight to the development of axillary buds).Race Gloire de Lauren includes compact low-growing plants with small leaves and flowers of different colors, bloom very profusely.The most famous varieties of "Carolina" - flowers are dark pink, "Competitor" - flowers are dark-pink color;"Marina", "Egers Favorite" - flowers are dark pink;"Rosemary" - flowers pink.Begonia tuber ♦ Poligibridny view.Stem juicy, translucent, thick underground tubers.The leaves are heart-shaped, somewhat asymmetrical, the next may have a different pattern.Flowers are diverse: can be simple, semi-double and double, a variety of colors, size divided into huge (approximately 20 cm in diameter) krupiotsvetko-tions (with a diameter of 8 to 10 cm) and multiflorate (many flowers, with a diameter of3 to 5 cm each).Sometimes there is a group in the form of flowers: rozovidnye, nartsissovidnye, Peony- and other varieties (most known): "Dark Red" - semi-spreading, bright green leaves, macranthon, double flowers, dark red;."Dark Scarlet" - compact, dark-green leaves, polyanthous, double flowers up to 4 cm in diameter, dark red;"Yellow" - semi-spreading, light green leaves, macranthon, flowers, simple, yellow;"Orange" - semi-spreading, macranthon, doubled flowers, orange;"Rose" - semi-spreading, bright green leaves, macranthon, doubled flowers, pink;"Scarlet" - spreading, macranthon, double flowers, pink and red;"Salmon Rose" - sprawling, bright green leaves, macranthon, double flowers, pink.The requirement to moisture: water-loving plant, but from an excess of water can be lost.In no case do not use spray irrigation and cold water.In the period of rest (winter) watering begonias should be only after the complete drying of the surface of the earth coma.It is important to maintain a stable humidity (without sudden changes).
Temperature: feels good in the range from 13 to 22 ° C, but it does not like rapid and frequent changes in temperature (can dump the leaves).He prefers the stability or gradual change.Tubers were stored at a temperature of about 10 ° C.For the period of budding desirable temperature just above sredneoptimalnoy (20 °), after flowering it is possible to reduce up to 15 ° C.The seeds germinated at a temperature of about 25 ° C.
Light mode: prefers partial shade.Direct rays reduce the decorative.Many clearly defined photoperiodism (short-day).It is possible, growing begonias in long-day conditions, in compliance with the requirements for temperature and correct lighting to achieve flowering in the winter months.To do this, you need to provide 14 hours of light per day in September and October (ie for two or two and a half months before flowering).For artificial illumination lamp enough for 60 watts.Tuberous begonia, unlike other species, can be grown on the southern windows.
requirement to the ground: all begonias suitable mixture of leafy, sod and humus land with peat and sand in the ratio 3:0,25:0,5:1,5:1, but some species are even more favorable deviate from itoptions: for large bushy plant, it is desirable to increase the proportion of humus;for young plants begonia blossom forever and slender peat is not included, whereas for tuberous begonias he needs to maintain the desired acidity (pH 6 - 6.5).Feeding - moderate and only during the active growing season, but in the case of an adequate supply of dry fertilizer application in the spring is not required.Tuberous begonias feed required.
Reproduction: 1. stem and leaf cuttings (You can also use part of the sheet, but in this case it is necessary to handle them very carefully, as they are prone to rot).On petioles desirable to make cuts in places of branching veins.Rooting leafy cuttings in sand or moss and sand mixture (1: 4), pressing them to the substrate stones (pebbles).The substrate must be sterile.2. By dividing rhizomes.3. Seed (they are very small), are sown without termination.Shoots emerge in a month or two, they must dive at least twice.Features: for most contraindicated turning to light.The premises where the begonias grow, it is desirable to ventilate.The rest period is well defined.In tuberous species in the rest period withering shoots are cut off.For most types of obligatory nipping.
