The genus Hoya, belonging to the Lastovnev family, owes its name to the English gardener Thomas Hoy, who served as the main gardener at the Duke of Northumberland in the castle of Sion House.
For the first time, plants of this genus were described in 1810 by the researcher and natural scientist Edmond Val, who gave the genus a sonorous name - Sperlingia. But the circumstances were such that the first manuscript was published by Robert Brown, who also described plants of this genus and named the genus in honor of his friend Thomas Hoya.
Hoya is a lignified liana with long shoots and fleshy dark green leaves. More than two hundred species of these plants grow in India, South China, the Pacific Islands and Australia. The flowers of the plant are waxy, star-shaped. A quick look at them, it seems that they are made of plastic. Umbrella inflorescences usually consist of twelve to fifteen white, with a pink crown, flowers. In hot weather, sweet nectar drops appear on them. The flowers have a very pleasant, incomparable aroma. Depending on the conditions, the flower can "live" for several weeks. During flowering, pots with plants should not be rearranged to a new place - the flowers are quite fragile and can fall.
In culture, meaty hoya or “wax ivy” has become most widespread. This is a fairly large climbing plant, which with its shoots can braid vertical supports or plants growing nearby. In height, it can reach one hundred and twenty centimeters. Flowering continues from May to September. Depending on the variety, the leaves may have a creamy white rim or a yellowish stripe in the middle.
Other types of hoya also deserve attention: lace, beautiful and multi-flowered.
The lace hoya is somewhat similar to the meaty hoya, but smaller in size (up to 90 centimeters) and has more delicate leaves.
Beautiful Hoyu is best grown in a hanging pot or flowerpot so that the shoots hang down. The flowers of this plant are white with a purple-red edging, waxy, collected in large inflorescences. And most importantly - very fragrant.

The hoya has multi-flowered flowers of a delicate yellowish-green color and practically does not smell.
Hoya is kept in a bright and warm place. The soil should always be slightly moist, and the leaves should be often sprayed. From October to February, watering must be reduced, the temperature in the room to maintain about eighteen degrees Celsius. If the winter is too warm, the plant may lose some of its leaves.

Hoya is propagated by apical or stem cuttings. The peculiarity of plant propagation is that even in a special container with heated soil, cuttings root for a long time - from six to eight weeks.
It is better not to transplant adult plants without the need, and if it is nevertheless required, then the pots should be selected a little more than the old ones and always with good drainage.
