Allamanda is one of those spectacular indoor plants that attracts flower growers with the versatility of forms and the riot of colors of beautiful large flowers. An exotic flower will make any interior unique and inimitable, although it is a rather rare guest in ordinary apartments. Of course, there are many difficulties in caring for such an exotic, but a beautifully flowering allamanda will become a real pride of its owner and will certainly arouse admiration among guests.
It is interesting! Such an unusual name for flowering plants was given in honor of the outstanding Swiss botanist, professor at the oldest university in the Netherlands in Leiden – Frederick-Louis Allamanda. In the people, the flower is often called the “golden mouthpiece.”
Allamanda is a genus of 15 species from the Kutrovye family. These are evergreens – shrubs and vines. The birthplace of exotic guests is South America, in particular the tropical rainforests of Brazil.
Allamanda laxative won the greatest popularity among Russian flower growers. This is a shrub that reaches a height of 2 m, or a vine that can grow 5 m in length. Elastic stems are light gray in color, and leaf blades are arranged oppositely or in whorls of 3-6 pieces. Dark green outwardly smooth leaves 6-16 cm long and 2-6 cm wide have an oblong shape with a wedge-shaped base and narrowed towards the top. The lower surface of the leaf blade is slightly lighter than the outer surface and may be slightly pubescent.
Large tubular-funnel-shaped bright yellow flowers up to 10 cm in diameter are folded into apical corymbose inflorescences. Each flower consists of a 5-tiled calyx and a corolla of 5 rounded petals connected downwards and having a limb, therefore, outwardly resembles a bell familiar to everyone. The fruit is a 3-cm box, which opens with 2 flaps.
Advice! In summer, with warm nights (above 15 ° C), plants can be kept on a balcony, an open terrace or outdoors.
Allamanda laxative in floriculture is represented by several decorative forms that differ in the size and color of the flowers.
Basically, they are all fast growing.
- Large-flowered – an evergreen shrub from 40 to 2.5 m high with thin stems, lacental leaves and large yellow gramophone flowers.
- Schotta is a vine with wide lanceolate leaves and yellow flowers that have a darker throat color and characteristic brown stripes on the petals.
- Henderson – differs in large flowers of an orange-yellow hue with lighter spots on the petals.
- Purple – unlike the yellow allamanda, the bush has red flowers.
- Violet is a shrub with long ellipsoid-shaped leaves and chic lilac flowers.
- Oleandroleaf is a low shrub with drooping stems, pointed elongated leaves and relatively small pale yellow flowers.
In addition to varieties with simple flowers, the terry allamanda looks very chic, which has a large number of golden yellow petals in each flower.
Important! All parts of the plant secrete milk – latex, which can cause irritation, so it is better to wear protective gloves when in contact with allamanda. Plants also contain a laxative substance.
Features of care
First of all, a set of measures for the care of the allamanda should be aimed at providing conditions that are as close as possible to the natural habitat.
The plant needs:
- a container with a good drainage layer;
- sufficient nutritious substrate;
- a lot of light and heat;
- abundant watering and high humidity;
- top dressing;
- shaping cut.
It should be borne in mind that, based on the dimensions, allamanda requires space, as it can grow both in height and in width. Although breeders are also working on dwarf varieties that do not exceed 50 cm in height.
In addition, in winter, the plant needs a dormant period, so from October watering is reduced by 2 times, top dressing is not applied.
Light-loving allamanda should be kept in a well-lit place. The minimum time to receive direct sunlight is 4 hours daily. But direct exposure to scorching rays should be avoided, as the plant will get burned. When the duration of daylight hours begins to shorten, the flower needs to be illuminated with artificial light lamps, and preferably special fitolamps.
A heat-loving plant, in principle, tolerates room temperatures well, the main thing is that the mark does not fall below 13 °C. Average temperature ranges: in summer – 20-25°, but not higher than 27°, in winter – 13-15°. Flowers should be protected from drafts.
Watering and humidity
Allamanda, like all inhabitants of the tropics, is very fond of humidity. Watering is plentiful, especially in the hot summer period and moderate in winter, only after the upper earthen layer dries out. Always make sure the topsoil is not damp before watering. The flower responds well to spraying with soft and warm water, but drops should not accumulate on the buds.
Particular attention is paid to humidity in winter. If the air is very dry (below 50%), then you can use trays with wet pebbles, household humidifiers, or a decorative indoor fountain.
Use fertilizers for ornamental flowering plants with trace elements and infused organic fertilizers. Top dressings begin to be applied from early spring 1 time in 14 days, alternating mineral and organic matter.
In November or already at the end of winter, cardinal forming pruning can be carried out, removing 1/3 or even 1/2 of the length of the stems above the leaf internodes. Dwarf forms are usually pruned moderately. Regulatory pruning is periodically carried out, removing old, damaged and heavily thickening branches. To give a beautiful decorative shape throughout the year, it is recommended to pinch the tops of young shoots.
Allamanda is usually transplanted in the spring. Young plants – 1 time in 1-2 years, with the age of 1 time in 3-5 years. The soil must be sufficiently fertile, moisture and breathable.
Ideal substrate for:
- sod land – 1 hour;
- leaf ground – 2 hours;
- humus – 1 hour;
- peat – 2 hours;
- sand – 0.5 h.
The older the plant becomes, the denser the soil is selected. Good drainage plays an important role.
Exotic plants can be propagated by seed and vegetative methods.
After flowering, a few flattened seeds with fleshy contents ripen in the fruit-box. They are harvested and sown in a light, fertile and well-moistened substrate, covered with glass or polyethylene and kept at 25°C. Mini-greenhouses ventilate daily and monitor soil moisture. Seedlings should sprout in 3-6 weeks. Young plants retain maternal qualities.
The easiest way is propagation by cuttings. To do this, in early spring, last year’s apical semi-lignified cuttings are taken about 10 cm in length. They are rooted in sand or in a moist light substrate with the addition of sphagnum. For better rooting, you can treat the lower part of the cutting with a rooting biostimulator and make a mini-greenhouse by covering it with a glass jar. The cuttings are kept in warm conditions of 22-25 ° C and watered periodically.
Possible Growing Difficulties
Allamanda must be provided with support in the form of a lattice. The lashes bend well and you can create an interesting decorative composition from them.
If the plant develops poorly, the color of the leaf blades fades, and flowering is poor, then the reason for this may be a lack of light and a lack of nutrients. If the flowers are kept in too cold conditions or constantly exposed to drafts, then the leaves begin to turn brown and curl. The reason for the weak formation of buds may be too thickened crown.
Of the pests, flowers can be attacked by aphids or mealybugs. In this case, it is better to treat the plant with insecticidal preparations. Of the fungal diseases, root rot is the most common, which occurs when waterlogged and is treated with fungicides.
Although growing and caring for an exotic beauty at home is very problematic, if you make some effort and try, then allamanda will definitely reward you with a chic appearance and wonderful flowering.
