Weltheimia


Veltheimia is an exotic flowering bulbous plant from South Africa, belonging to the Liliaceae family and attracting the attention of gardeners and florists for its unique bright appearance and high decorativeness. The culture that came to our region from the hot climate has adapted to the new living conditions and feels great on the garden plot and as an indoor flower. In warmer regions, the southern beauty can hibernate in the open field, but she will need a reliable shelter. In cold areas with severe frosts and long winters, Weltheimia can only be seen indoors. A place for growing African culture can be a winter garden or balcony, a greenhouse or a terrace, a windowsill or a loggia. In any place, she will not leave anyone indifferent and will attract attention with her southern charm.

Individual features of weltheimia are wide bright green lanceolate leaves (about 30 centimeters long), collected in a rosette and resembling dandelion leaves, tall powerful peduncles with a smooth surface, bizarre inflorescences in the form of a brush or spikelet of a large number of tubular flowers of pink, white, purple, dirty yellow, reddish and lilac shades and fruit-boxes. The root system consists of large bulbs (more than 7 centimeters in diameter), the surface of which is covered with pink scales. The average height of a perennial is 40-50 centimeters.

Weltheimia care at home

Location and lighting

When choosing a place, it must be borne in mind that the bulbous perennial Veltheimia does not tolerate cold drafts and reacts negatively to them. Unpretentiousness to the level of humidity and pollution allows you to grow Veltheimia even in the kitchen.

Both outdoors and indoors, the southern Weltheimia plant needs bright sunlight. With a lack of light, the flower loses its decorative effect. A sufficient amount of light and heat can be received by the weltheimia on the windowsills on the south or east side of the dwelling, as well as on glazed loggias, terraces and balconies.

Landing Weltheimia

The special flower Veltheimia is not planted like most plants in spring, it is recommended to plant it in late summer or at the very beginning of autumn.

The volume of the flower pot depends on the size of the bulb. Its diameter should be 2 times larger than the diameter of the planting material.

It is recommended to plant the bulb in the ground so that its upper part is flush with the soil surface in the pot.

Temperature

For the full development and growth of weltheimia, a stable temperature is required - from 10 to 20 degrees Celsius. When the temperature drops below 10 degrees, the flower will react negatively, since it is not very hardy and unstable to cold. Interestingly, the flowering period of Weltheimia can only begin in cool conditions at a temperature of 14-15 degrees.

Watering

Bulbous crops and weltheimia, among them, have a negative attitude towards water spraying, but irrigation should be carried out regularly in moderate amounts. After the appearance of peduncles, the frequency of watering and the volume of irrigation water must be increased, since the plant is actively preparing for flowering. After its end, when the leaves begin to turn yellow, watering can be stopped completely until next September.

Air humidity

The humidity level is not very important for a indoor flower, so it can be grown in any room.

The soil

The optimal soil composition for growing Weltheimia is a mixture of leafy soil, turf and coarse river sand. All components must be taken in equal quantities. The plant thrives on fertile soils with a high content of compost, but does not like mineral supplements.

Top dressing and fertilizers

Complex feeding of Weltheimia is required only during the period of active growth, especially when peduncles appear. It is recommended to use liquid fertilizers.

The "bracts" species can be grown in a pot in the garden in the summer, so watering and feeding does not stop. Watering is moderate, fertilizers are applied every 2 weeks.

Transfer

Every 2-3 years, the flower needs to be transplanted into a larger pot and a new substrate. After transplanting, a third of the bulb should remain above the surface of the substrate.

Reproduction of weltheimia

The easiest and most common way to propagate Weltheimia is to use daughter bulbs. After separation, each copy is planted in an individual flower container.

Types of weltheimia

In its genus, the exotic plant Veltgeimia has 6 species, but the most popular because of its unpretentiousness in growing and care, as well as because of its high decorativeness are Veltheimia "Cape" and "Bracts".

Bracts Weltheimia

It differs from other species by very wavy leaf plates reaching a length of 30 centimeters and unusual peduncles with a spotted surface. The flowering period begins in the last winter weeks. On the peduncles, numerous flowers of a pinkish-green hue appear, collected in inflorescences with a diameter of 10 centimeters. On one peduncle, up to 60 small flowers gradually bloom, which delight with their beauty for one month or even more.

Cape Weltheimia

The plant has its own characteristics. It has very wide (10-12 centimeters) leaves, resembling the shape of a cap due to the blunt top and several longitudinal folds on the surface. There is an unusual spotting at the base of the light green leaf blades. The inflorescence in the form of a brush consists of drooping light red and yellow-green flowers. The average height is about 50 centimeters.

Weltheimia is considered one of the most unusual and attractive potted plants to bloom in the winter. Depending on the climate, the flower can be kept in a garden or flower garden, in an office or on a terrace, on a windowsill or in a winter garden, on a veranda or on a balcony.


The value of FEEDING PLANTS in the Great Soviet Encyclopedia, TSB

plants, fertilization under the agricultural. crops during their growing season is an agrotechnical method aimed at improving plant nutrition and increasing their yields. When root feeding, fertilizers are applied to the soil, and nutrients are absorbed by the roots when foliar is applied - the plants are sprayed with fertilizer solutions, and the nutrients penetrate into them through the leaves and stems. Etc. was first used by the German scientist P. Wagner at the end of the 19th century. In Russia, the first experiments with surface application of fertilizers (nitrate) for oat seedlings were carried out at the Derebchinsky experimental field (Ukraine) at the end of the 19th century. Despite the positive results (an increase in yield up to 6 centners per hectare), the method was not widely used. In the USSR, fertilizing with mineral and organic fertilizers began to be used on large areas since 1935.

The following methods of fertilization are widespread: dry fertilizers are scattered (without embedding) with fertilizer seeders, spreaders or from an airplane (top dressing of winter crops, rice, etc.); sometimes dry fertilizers are manually scattered and sealed with harrows, cultivators, and other tools. plant feeders, as well as together with water when irrigating with sprinklers and irrigation machines. P.'s efficiency. depends on the properties of fertilizers, their solubility in water and the degree of movement in the soil and on the weather. For feeding, mainly water-soluble fats are used: nitrogen - ammonium nitrate and urea, an aqueous solution of ammonia, sodium nitrate (for feeding sugar beets), all potash fertilizers from phosphorus fertilizers - superphosphate. Local fertilizers (ash, slurry, bird droppings, well-rotted manure) and micronutrient fertilizers are used.

Early spring (on frozen soil) feeding of winter crops is of great importance. After spring revitalization, before heading, they consume the greatest amount of nutrients, which are usually insufficient in the soil during this period (fertilizers applied before sowing are absorbed by the soil, washed out by precipitation, consumed by plants and microorganisms), and the nitrification process is still suppressed by low temperature and high humidity. The greatest increase in yield is observed when a complete fertilizer containing N, P2O5 and K2O is added to the top dressing. In areas of sufficient moisture, it is advisable to apply nitrogen fertilizers in 2 terms - in early spring and before the plants enter the tube. The average dose of fertilizers for fertilizing winter crops is about 60 kg / ha NPK, the average yield increase is 3-5 centners per hectare. From row crops, cotton, sugar beets, rice, and others are fed during irrigation. they are used annually on an area of ​​about 40 million hectares. Abroad, this technique is widespread in France, Italy and other European countries, in the USA and Canada.

Weltheimia

• bulbous plants common in South Africa
• in room culture 2 species

Genus Weltheimia, or Weltheimia (Veltheimia) family Hyacinth (Hyacinthaceae) includes only 2 plant species endemic to South Africa and Namibia.

The genus is named after August Ferdinand von Weltheim (1741–1801), the German patron saint of botany.

Weltheimia bracts (Veltheimia bracteata) - grows in forests and coastal shrubs in the east of the Cape Province of South Africa. It is called Forest lily, Forest sand lily.

It is a bulbous plant with a short dormant period during the dry summer season. In areas where precipitation falls throughout the year, it behaves like an evergreen, retaining leaves. The bulb is round, white or slightly greenish, covered with dry last year's scales. The leaves form a rosette about 25 cm high and 35 cm wide, beautiful, glossy, green, fleshy, broadly lanceolate, grooved along the midrib, up to 30-45 cm long and 8 cm wide, often with wavy edges. The flowers are collected in simple brushes of 30-40 at the top of the peduncle up to 60 cm high. The color of the flowers can be pale pink, dark pink, orange-pink, sometimes greenish-yellow. In the buds, the flowers are held vertically, and when opened, they hang down. The tips of the flowers are sometimes green or with green spots. The inflorescence lasts about a month. Fruits are large membranous swollen capsules with black pear-shaped seeds, about 6 mm long.

It has varieties and varieties, the most famous of them are -

  • Lemon Flame - with greenish-lemon flowers.
  • Lemon Blush - The flowers are lemon yellow at the base, pink at the ends.

Cape Weltheimia (Veltheimia capensis) - grows in the more arid northwestern, western, southwestern and southern parts of South Africa and in southwestern Namibia. Known as the Sand Lily.

Deciduous species 25-45 cm high. Bulb up to 7 cm in diameter, ovoid or spherical, fleshy with a protruding bottom, from which perennial fleshy roots come. The top of the bulb is often bare, and the entire bulb is covered with creamy white scales, sometimes with light brown stripes. Leaves up to 30 cm long, 10-12 cm wide, narrow-, wide- or obverse-lanceolate, have different colors, widths and lengths. They are located in the form of raised, curved, spreading or falling rosettes, grayish-green or bluish-gray, slightly or strongly grooved, wavy to varying degrees or curved along the edge. The peduncle is hard, with purple or maroon spots, protrudes from the center of the rosette and is covered with a grayish powdery coating. It bears a dense cone-shaped raceme of narrow, uniformly pink, pink-speckled or less often light yellow tubular flowers, sometimes with cream tips. Each flower is located at the end of a short pedicel and has a lanceolate bracts and one or more narrower bracts. The fruit is a large, papery, hexagonal capsule consisting of 3 compartments (locules) with 3 protruding wings. Each compartment contains 1 or 2 seeds. When ripe, the capsule opens at the tip. The seeds are hard, pear-shaped, dull black, with a highly wrinkled shell, at the end with a narrow structure known as stropiola.


Weltheimia


Weltheimia (Veltheimia). Family: Liliaceae - Liliaceae, native to South Africa.
Weltheimia is a beautiful flowering and decorative leafy plant found in the eastern Cape region of South Africa. Bulbous, well adapted to indoor conditions. Of the six species of this genus, the most common: green-flowered Weltheimia-V. viridifolia, c. Cape - Veltheimia capensis, V. bracteata. The plant blooms in winter and early spring. In Europe, this plant became known as the "winter torch".
A pink racemose inflorescence, perched on a peduncle up to 50 cm in length, appears in winter and spring. Unfortunately, the flowering plant must be kept in a cool place with temperatures no higher than 10 degrees. It was most popular in the 20th years of the twentieth century. Unfortunately, it is now almost forgotten.

V. Cape - V. capensis DC.
Bulbous perennial plant. Bulb, half submerged in soil, pear-shaped or oval, up to 7 cm in diameter. Its outer scales are scarious, light brown or lilac. Leaves are light green, often spotted at the base, up to 30 cm long., 10-12 cm wide., Oval-lanceolate, wavy along the edge, with several longitudinal folds, obtuse at the top or drawn into a small cap. The flowers are drooping, collected in a racemose inflorescence on a leafless peduncle up to 50 cm high. Pedicels in the lower part with reddish-brown spots. The perianth is narrowly bell-shaped, almost cylindrical, up to 4 cm long. Its base is light red, the upper part is yellow-green. Homeland - South Africa. Grows on sandy hills, sea coasts, in shady places. In culture from the middle of the 18th century.

Location
kept in cool (+ 12C), well-lit rooms. Reacts negatively to drafts.

Lighting
Bright light

Watering
regular from spring to summer, strictly limited during the dormant period. After flowering, watering is reduced, after the leaves die off, watering is stopped until growth begins

Air humidity
Moderate

Care
a flowering plant should be in a cool place with a temperature not higher than + 10C + 12C degrees, under other conditions it is more difficult to achieve its flowering. Only when new leaves are forming, the temperature can be up to + 20C. Perhaps that is why the weltheimia are not very popular. After flowering, the plant remains green until early summer, when a dormant period begins. In summer, plant pots are placed in a darker place and rarely watered until they completely shed their leaves. At the end of September, the leaves begin to grow again. At this time, the bulbs need to be transplanted into fresh soil. The initial temperature for better bulb growth is + 20C, watering so that the earth is slightly damp. As soon as new leaves appear, more watering and fertilization is required. The plant is rearranged in a cool room, in October - November a peduncle bud appears. Blooms from December-January to March-April. Top dressing: with the beginning of foliage formation and before it dries up, once every 4 weeks with a semi-concentrated flower fertilizer (with no nitrogen).

Reproduction
baby onions in late summer or early autumn (September is optimal), which are separated during transplanting and planted in several pieces in low, wide pots, without burying them in the ground. Less commonly, seeds, which are tied with artificial pollination of flowers. A plant grown from seeds blooms for the 3-4th year.

Transfer
every two years, in September. When transplanting, the roots are carefully examined, removing all dried and rotten ones, and the bulb is planted so that it rises by one third above the surface of the earth. The pots had to be large, since the plant has large foliage. The soil mixture is made up of turf, leafy soil and sand.

Possible difficulties
the plant is susceptible to fungal diseases and mold.


Green-flowered Veltheimia (Veltheimia)

Liliaceae family.
Blossoming in December and March.

Bulbous plant, giving a rosette of beautiful light green elongated, wavy at the edges, soft to the touch leaves up to 50 cm long. On tall leafless peduncles (up to 40-50 cm), racemose inflorescences (sultan) with tubular salmon-pink flowers (at the base, greenish petals) rise.

An original plant that requires moderate lighting, air temperature in winter in the range of 18-22 ° C, not very abundant watering during the growth and flowering period. After flowering, the plants are placed in bright, well-ventilated rooms, but not in direct sunlight.

Veltheimium bulbs require a dormant period from April to August, during which they shed their leaves. The bulbs are stored in the same container in a dry state (no watering).
Watering is resumed after transplanting in late August - early September, when the plant shows signs of awakening growth.

The soil mixture for transplantation is prepared from sod (three parts), greenhouse and deciduous lands (two parts each) with an admixture of sand and a small amount of bone meal. The bulbs are planted flush with the soil surface in a pot. It should be transplanted every two years.

Propagated by separating baby bulbs during transplantation. The separated plants are planted in low small pots or in bowls - several in each.
