Coleria

The Gesnerian family. Homeland - tropical regions of America. About 50 species are widespread in nature.

These are herbaceous plants with straight and lodging stems with age. They have a scaly underground rhizome, thick, elongated, light brown. The leaves are large, opposite, ovoid-oblong in shape. The color of the leaves in different species can be dark green with reddish pubescence along the edge of the leaf, like in the Coleria hairy Kohleria hirsuta; light green, like Kohleria digitaliflora foxglove; silvery green with purple stripes along the veins, like the Coleria of the pleasant Kohleria amabilis.

Flowers are either single, or collected in 2-3 on the axillary peduncle. Corolla bell-shaped with a tube up to 5 cm long and five wide petals. The color of the flowers is from pale pink, bright orange to purple-brown. Usually the color of flowers is variegated, interspersed with a different color.

Coleria - care and cultivation

Caring for Corelia during the growth period is no different from growing Saintpaulias, the same soil and top dressing, watering frequency and illumination. But unlike the uzambar violet, koleria has a pronounced dormant period. It requires cold maintenance, otherwise, during the winter, the plants grow, stretch out strongly, wither, the rhizomes lose their vitality.

Temperature

Like all Gesneriaceae, during the growing season, which lasts from late February to November, Coleria prefers moderate temperatures around 20-25 ° C, does not like dryness and heat above + 28 ° C.

Coleria has a dormant period, during which it is not necessary to cut off the aerial part of the plant. You can simply move the pots to a very cool place. The optimum temperature during rest is about + 12-15 ° C, at least 10 ° C. But you can also dig up the roots of the Corellia and put them in an airtight bag in sawdust or coconut substrate, which is slightly damp but not soggy. Place the bag in a dark place at 8-10 ° C and store without watering until the end of winter.

Lighting

Coleria is photophilous. She needs bright light, shaded from direct sunlight only during the hottest hours of spring and summer. It grows well on light, not hot windows, or under shading from a mosquito net or tulle. It takes about 12 hours of good bright light for good growth and flowering, morning sun or after 5 pm - very beneficial for the formation of a dense bush.

Watering and humidity

In the summer, koleria is watered quite abundantly, but by the next watering, at least half the height of the pot, the earth must have time to dry out - remember that the root of the root is a water-storing organ, with excess moisture it decays. In the fall with a cold snap, watering is reduced, the soil is well dried. In winter, with a cool content, they are watered occasionally, preventing only the complete drying out of the earthen coma. If the plant continues to be kept in a warm room during the winter, it must be watered.

Coleria loves high humidity, but does not tolerate the ingress of water on the leaves. Therefore, the air is humidified in other ways: by turning on a humidifier, placing pots on pallets with wet pebbles or sphagnum moss. But usually this need arises only on very hot days in summer, when the air humidity is below 40%.

Top dressing

From April to August, koleriya should be fed with fertilizers for Saintpaulias in full dosage or fertilizer for flowering indoor plants, in a dose half the recommended one. Top dressing is carried out every two weeks. They do not feed in autumn and winter.

Transfer

For the cultivation of koleria, rather wide pots, low height, hanging baskets are used. It is imperative to make large holes at the bottom of the pot and pour drainage, about 1.5 cm high. Plants are transplanted annually in spring, you can start in February. Soil mixture: 2 parts of leafy soil, 1 part of coniferous, 1 part of baking powder (coarse river sand or vermiculite). Shop soil for Saintpaulias or Terra Vita universal will do.

Reproduction of coleria

The color is propagated by apical cuttings, seeds and rhizomes. It is better to root the apical cuttings no earlier than March. Cut off the tops of the shoots, about 7-10 cm long, tear off the two lower leaves and put them on rooting in water or in the ground.

Rooting in the ground as follows: sterilize the prepared soil (as described above) (required!) And cool. Pour over the drainage into a pot. Make a depression with a pencil and insert the ends of the cuttings there. It is advisable to plant at least 3-5 cuttings in one pot, so the bush will be lush. Then lightly compact the soil around the stems and moisten. No need to water abundantly - the soil should be slightly damp - sprinkle with a spray from a spray bottle under each cutting. Place the pot in a clear bag. Inflate, tie. Air for about 20-30 minutes twice a day. It usually takes 4 to 6 weeks to root.

Coleria is propagated by rhizomes during transplantation. You need to cut off a piece of rhizome with a growth bud. Coleria rhizomes look like thick hairy worms, if they are dormant (no shoots and leaves), cut off about 10 cm of rhizomes. If there are already shoots, cut off a smaller piece with a twig. The soil for planting must be sterilized. Bury the rhizomes in the soil no more than 3 cm, place them horizontally. Water very carefully until young leaves appear. You do not need to cover the pot with planted rhizomes.

Coleria from seeds

  • Coleria seeds are sown at the end of January or February, scattered over the surface of the earth (leafy soil in half with coarse sand, or universal peat soil for seedlings, also in half with sand).
  • The seeds are not sprinkled with earth on top, but are sprayed and covered with glass or film and aired 2-3 times daily until shoots appear.
  • Seeds germinate at a temperature of 22-24 ° C. After the appearance of two pairs of leaves, the seedlings dive, planting one copy in small pots. It is better to take pots about 8-10 cm in diameter, not high.
