For lovers of climbing plants, hoya can take its rightful place in the home flower collection. Three groups of hoya are suitable for home cultivation: ampelous, curly (liana), and shrubby. These groups, in turn, include various varieties. As an indoor culture, hoya is most often bred - a vine or "wax ivy". This is an unpretentious and beautifully blooming flower.
Hoya is an evergreen tropical vine of the Kutrovy family (dicotyledonous flowering plants). The natural habitat is Indochina, the Malay archipelago, the western coast of Australia, as well as the islands of Polynesia. Hoya grows mainly in woodlands, using tree trunks for support. In height, it can reach up to 10 m. Young shoots of a dark purple color are initially bare, but as leaves appear on them, they gradually turn green. Aerial roots are formed on them, which are then lignified. The leaves are oval - pointed in shape, shiny, depending on the type, fleshy or thin. Flowers, consisting of five fused at the base of the petals in the form of wax stars, are collected in umbrella inflorescences.
The pedicel is up to 5 cm long. The diameter of odorous flowers is usually 1–2 cm. But, for example, in the “Imperial Hoya” flowers reach 8 cm.
The location for the hoya is better to choose bright and preferably on an ongoing basis. Because the blooming hoya does not like a change of place. The best option would be the western and eastern windows. On the north side of the house, light will not be enough for flowering and you will have to do some backlighting.
And on the south side it is too hot and will need to be shaded. The pot is small or plastic or ceramic, even if it’s tight. A capacity of 15-22 cm in diameter is sufficient for an adult plant. In ordinary soil, flowering of hoya may not occur, therefore, special soil is needed. You can use a substrate for orchids or make a mixture yourself from the following components:
- Soil for succulents;
- Tree bark or coconut chips;
- Ground moss sphagnum;
It should be remembered that with the growth of the plant, the larger the pot, the larger the components of the soil. The temperature for active growth is + 22- + 25 degrees. In winter, + 16- +18 is allowed. Watering in spring and summer is plentiful, as the soil dries. Abundant spraying on hot days is also welcome. It is optimal to use rainwater, but well-maintained and suitable. In winter, spraying is excluded, and watering depends on the room temperature. The colder the less watering.
Hoya can be propagated by seeds, layering and cuttings. Cuttings are considered the most successful way. Suitable for this time is autumn and spring. The shank must have at least two leaves and two buds. The shoot is put into the water, where it must give root. Top dressing should be carried out only in the spring and summer months with complex mineral fertilizers for flowering plants or for orchids. An adult hoya transplant is recommended every two to three years, and a young plant every spring. The pot at each transplant is selected 2 cm more.
With proper and very simple care, an exotic hoya will delight with spectacular and long flowering.
